Slack is a very good tool for internal communications. You need to configure it right and impose discipline. We share on Slack anything that is technical and about the product.
CEO - Jack Media
I use Slack to communicate with our blogger. I do not need to go very deep into its functionalities at this point.
Founder - Nicely Noted
Francesco (one of our team-mates) is a great supporter of Slack and he’s right. Slack is very flexible and helps us keep track of a lot of threads at the same time.
Co-founder & CEO - Ludwig
Our teams like Slack. It has some good integrations. I cannot keep up with it as I get 2000 messages a day and cannot possibly check them all, but it is good team communication.
Founder & CEO - Embroker
We also use Slack--we like that it integrates very well with many other services (JIRA, BitBucket, etc.)
Gian Luca Petrelli
Founder & Executive Chairman - BeMyEye
I really love Slack because you can connect everything to it; we even connected our own database to get notified when people sign up.
Co-founder & CEO - Recruitee
We’re a Slack shop for sure. Early on, it was really great for reducing our email and time in Gmail. It keeps the noise down. You have to have good time management with Slack or else it becomes a distraction. I’m a big fan of Slack because it takes away from email. Email is harder to organize as opposed to just storing and having messages in a Slack conversation. In Slack, people have to be more succinct in their messages. Emails can get lost as people plan out their messages.
Co-founder & CEO - Roadmunk
We connect JIRA through Slack as a channel and it lets me get visibility for everything that’s happening from an engineering standpoint. Slack is amazing! It’s amazing because it’s not like Skype, and it’s not like Gchat. It’s very light and we use it for everything. Even dumping notes from our meetings. If I’m having a call with someone, I would put all those notes in Slack to check on them later, while continuing our discussion. It’s really great. Their mobile and desktop apps are amazing. I do a lot of BD work so for conferences now, when I’m on floors I’ll have Slack open and have a channel just for that event. I’ll have BD support on the same channel and take notes on the people I’ve spoken with. Slack creates one place for everything.
Co-founder & CEO - UCIC
We wrote our own bot that opens our doors for us. We hooked up Raspberry Pi and connected it to our bot so it will buzz our doors open.
Founder & CEO - Sproutling
We love Slack. The one time it went down, everyone was paralyzed. It has become absolutely essential to us. Only complaint is that there is no video chat feature yet – when / if such a feature were released, we could centralize all our internal communication onto the platform.
Co-founder & CEO - Qwilr
We use Slack for two purposes. On one side, we use it to manage email traffic as an email replacement. On the other side, we use it as a knowledge base. A lot of useful information, articles, and data are shared across the team with Slack.
Founder & CEO - Qardio
We are using Slack, and we have JIRA, Trello, Jenkins, and GitHub feeding notifications into it. It’s useful for team communication, but we’re not making heavy usage of it.
Co-founder & CTO - Valify
Slack is like cocaine--it is so addictive. Every communication ends up getting into Slack even if it does not belong. I end up using emails for more technical conversation, and to maintain a thread.
Co-founder & CEO - TravelPerk
We have a bot that gives us notifications for new customers. We’re pretty typical and post GIFs, talk about political issues and stuff. We post feedback on Slack that we get in different forms--and that all goes into a “feedback” channel that we have. It’s a good way for us to sort through and see who says what about our product and keep in mind what we’re trying to do.
Co-founder - Tend
We pipe-in new user sign-ups into one of our Slack channels. We have Mention hooked up and see when competitor mentions come in, alongside our own mentions. It gives us a close eye on the media lens.
Co-founder & CEO - Student Loan Hero
We chose Slack more for internal preference than actual product capability. It was the preferred tool of our engineer team. We evaluated other tools and we found out that most of them bring an equal amount of value, even though the features are slightly different.
CEO - TaskEasy
Slack is a good tool. As long as people within the company make good use of it, it is worth keeping. It is very easy to use; unfortunately it is not searchable, and has no threading.
Marketing Director - FreshGrade
I like Slack. Slack is great.
Co-founder - Outbound
Slack is a very good tool. It has cut down on internal emails. It’s just cleaner. We used to have another chat tool, but we would also send internal emails. It was difficult managing two communication tools. We’ve made the push for everyone to communicate using Slack’s channels and direct messaging. It’s been better than what we were doing before.
Marketing Manager - StreamLink
We’ve built a bunch of different automations into Slack. Whether it’s managing factors, client onboarding, or internal to-do lists, we manage a lot of it through Slack. It’s pivotal to our work flow.
CEO - ReviewTrackers
Slack is great. It handles all of our internal communication needs.
Founder - Magical Butter
Slack works pretty well.
Co-founder & CEO - getPartnered
We use a lot of bots and integrations with Slack. We use a ton of webhooks for getting notified of when bookings are completed, when payments are processed, etc. We use Slack for every single alert.
Co-founder - Beau
Slack is awesome! From the cutting down email standpoint, between Asana and Slack, we don’t send emails internally as a team anymore. That way it doesn’t load our customer facing communication channel. Slack with zaps is great for registration and things like that because it creates momentum without needing to tell the team. It gets everyone on the same page.
Founder & Managing Director - StartupRunner
Along with stupid, fun bots, we have an end-of-day integration that tells about the performance for the day. It gives us notifications if there is anything outstanding. Most of the company is moving to Slack, but Skype is still useful for video calls.
Co-founder - ShipBob
Slack helps us communicate and stay connected internally. We use it daily on our phones and laptops. It has many useful integrations, including Bitbucket, UserVoice and JIRA.
Co-founder & COO - Loopio
We’ve used other chat tools, but our customers and partners all use Slack and we can communicate with them on those channels. You have to learn how to use it: you have to be very diligent in setting the notifications so that it doesn’t get too distracting, and you have to agree with your team on the way to communicate through it. In terms of feature requests, I think threading messages is the main missing thing.
Founder - Waffle
For internal file sharing, we primarily use Slack.
Managing Director - Evoluted
Before we used Slack we used Skype, but there was a big lack of visibility of what was being said. Slack really changed how we communicate as a company. It has led to everyone sharing a lot more information within the company.
Managing Director - Evoluted
We did a whole scale move from our inboxes to Slack. All of our conversations happen on Slack now and the speed of communication has increased dramatically. We have our own document internally that describes how to use Slack and best practices.
Co-founder & VP Data - Zendrive
We don’t really use email. It’s just Slack. Our most used bot is one we built to order lunch. We use OrderAhead for team lunches. People used to forget to order (the deadline is 5PM the day before) so our "lunchbot" nags you to order lunch starting at 4PM. It uses Twilio and other APIs to bother people to order lunch. It has a 100% success rate. We’ve tried other helper bots but they weren’t that useful. One had been integrated with ChartMogul, but it was easier to log into ChartMogul directly.
Co-founder & CEO - Webflow
We started using Asana by default. It’s used by our non-technical team, which is quite small. I’m neutral on it. We aren’t thrilled or disappointed by it. A lot of things in Asana are long term, tracking projects. Everything on short timescales happens on Slack.
Co-founder & CEO - Webflow
We have a project management channel in Slack which shows all JIRA issues and updates. The releases we do with GitHub go into a releases channel, and then we have various private channels set up for talking to partners, customers, and contractors.
Co-founder & CEO - ContainerShip
We integrate Slack with everything and get notifications for when people sign up for our product, when people send support tickets, where they are in our funnel, and all of that goes into Slack. We use separate channels to respond to people. I wish they would move to threaded conversations, but I know their philosophy on that (if they have a philosophy on that).
Founder & CEO - Allay
We have a link on Preview for where people can ask for something or apply feedback. It’s good for posting. We get a Slack notification for any feedback.
Augustin de Préville
Founder & CEO - Preview App
I hate Slack, but my team loves it. I think it is a distracting resource. It makes too much noise and people aren’t really working because they spend more time on Slack.
Augustin de Préville
Founder & CEO - Preview App
We don’t use Slack too much… I used Slack two and a half years ago and it was so buggy, I found it hard to go back to it.
Founder & CEO - Pixc
We’ve had some great fun on Slack, and love experimenting with it to keep in touch. We’re actually going against their trend right now a little and tapering off a bit. Sometimes with the way we work, it doesn’t make sense to be sitting on Slack all day waiting, and it’s actually more convenient to send an email and then respond at your own pace. Sometimes when we’re emailing back and forth for a while, we’ll realize we need to talk faster, and head on to Slack or schedule a Slack meeting in the future.
Founder - Bamboo Supply
We were on Slack, but we abandoned it because it was distracting and just another tool to have open at all times.
Co-founder & CTO - MineWhat
Slack is great; the only problem is that it can be disruptive. It is nice to have things organized in a dashboard format.
Co-founder - Trove
We love Slack. Gchat is OK, but Slack is a much more robust tool and we have it integrated with our system.
VP Marketing - Moogsoft
We have Slack integrated with our project management tools to see different pushes. We have all our Twitter mentions, backlinks, Stripe integrations, support tickets, Trello, all integrated with Slack.
Co-founder & CEO - Process Street
We use the following Slack Bots/integrations: Coinflip, Bitbucket, Giphy
Co-founder & CEO - Limelight Health
We are using Slack, but honestly it’s a distraction. The bot is pretty interesting, but as a chat, it just gets noisy.
Co-founder & CEO - BottlesTonight
Slack is the main tool we use. It’s awesome. People are criticizing it because they say that it can be distracting, but we love it. It allows us to quickly exchange info with people that are remote.
Co-founder & COO - Fizz
We use Slack for some of our project management tasks.
Co-founder & COO - Fizz
We run a lot of things through Slack. It’s our interface for non-developers. There’s a lot of back-end stuff--log messages, signups, bills paid, etc. that when we want to surface, can get moved to Slack. New accounts have a notification and show up in a Slack channel. We don't have a data dashboard, we have a bot that posts all that stuff daily. When a user takes a major action (like disabling their account or adding a new one), it helps us keep track of those important users. Slack is great for internal communication, because now when I open my email, I know it’s from someone external to the company.
Co-founder & CTO - Beyond Pricing
It's fun, it works, and GIPHY is great. We’ve connected a lot of integrations and our own web hooks. We can search customers via Slack, etc. We use Slack religiously, and we’re big fans. We have a Twitter integration set up, so when someone communicates with our company Twitter account, we can get notified in Slack.
Co-founder & CEO - Lob
Fun, quick and easy to use!
Co-founder & CEO - Payable
It’s our internal group communication hub--we live, breathe and communicate on Slack. We also have an external channel on Slack where we host conversations for design thinkers and technologists.
President - MU/DAI
We went through everything - tried everything - and, for us, project management is Basecamp, with a healthy dose of custom tools and Slack. We tried Asana, but its complexity versus the simplicity of Basecamp was more of a barrier than an invitation. Teaching our team to understand how Asana is most exploitable was less valuable than just using Basecamp and filling in the blanks with Slack. This was the path of least resistance, since we figured out Basecamp + Slack = Happy Productive People.
President - MU/DAI
We have a geographically diverse team and over the summer, we are adding interns. It's a consistent way to communicate far better than other tools. Slack has been a good hub for our remote team.
Co-founder & CEO - Smync
Slack reduced a lot of the emailing back and forth. If there is an important notification to send out (like if the database failed), we can reach the entire team in real-time.
COO - Higher Ed Growth
Slack is life-changing. It empowers us to operate as a remote team very effectively. It replaces a lot of internal emails.
Founder & CEO - CloudPeeps
We use Slack for all of our communication. We are pretty active on it. It is great for sharing files. If you paste a Dropbox link, the receiver can check it on the spot. It is great for people that are travelling or working remotely. It is a lot easier than copying and pasting a link in an email.
Founder & CEO - Do
We use Slack internally. It manages the group dynamic very well. It takes care of all the groups that we have for each product. I really love Slack. It’s incredible that it started as a side project and now it’s a multi-million dollar business.
Founder - Andy OS
Slack works great to manage team operations.
Founder - Andy OS
We have a cool integration where you can get a notification in Slack for whenever anyone is looking at a document you send out.
Co-founder & CEO - DocSend
I think Slack has to figure out how to monetize. Slack is super easy. They cap you at 5 or 6 integrations. Every tool that we use is integrated into Slack. HubSpot, Stripe, and Chargebee reports, daily metrics and upward/downward trends get posted through Slack. We developed two internal bots that we named Jennifer and Jessica and they give us a report of the last 24 hours performance in the company and then break them down by country.
Co-founder & CEO - Occasion
Who doesn’t have Slack? We have our platform integrated into Slack. We get notifications through Slack when someone fills out a form or completes a survey on our website.
Founder & Chief Software Architect - PeopleVine
We use Slack as our internal communication tool. We use it also lightly as a project management tool, as we link to Asana with it. It doesn’t do scheduling but works for the instantaneous communication. Slack is working pretty well and they are constantly improving it. The search tool could be more clear.
Founder & CEO - Instapage
Intercom collects our feedback, then we use Slack to drive awareness of it and distribute it internally. We use Trello to categorize the feedback as bugs, modifications or enhancements. I wish Slack had a two-way integration. There’s really only a one-way integration for these tools. I want to integrate Slack into Trello instead of the other way around.
Founder & CEO - Kahoots App
We have separate plugins like TwitterBots.
Founder & CEO - Kahoots App
We have a lot of integrations off Slack to keep track of how people use our service. We can monitor the communication between our stylists and our clients in real time and observe if there are any issues that require a human touch to resolve.
Co-founder & CEO - Stylisted
We use Slack for both internal and external communication. We have a community of people that we built through Slack. Slack is very easy to use - setup is really fast and you can add groups quickly. The only negative aspect is that at the moment it does not have threading, so it does not let you track your discussions very easily. The message that you were interested in can get buried in other messages very quickly. I believe that they are working on implementing this feature.
Co-founder & CMO - Terminus
Slack is a great tool. It is great for internal communication; I wish it was better for external communication.
Founder - Engine
Slack has its own purpose; it is a very simple one line communication tool. I like the real time notification feature.
Co-founder & CEO - Tenantify
Flowdock was one of the first communication tools to come about. It was created a couple of years before Slack. Slack is very similar to it in many ways, and has some really appealing features but what is blocking us from using Slack is that there is no way to thread conversations. This feature is very important to us. Flowdock does it so well that we have not been using any email for internal communication - and it has drastically reduced the number of meetings that we need to have. Everything is very searchable in Flowdock. As we have people on different part of the planet, it is very good to be able to see all the correspondence in one place. We have also been using it to record some activities such as meetings and important events that happened in the company. This said, if Slack finally decides to implement that feature, we will probably switch.
Founder & CEO - AppGyver
Slack never crashes, it is easy to use, and we can create customizable private channels for each department. Our company lives on Slack.
Co-founder & CEO - Opternative
We have Slack integrated with our Asana. We also have our Stripe integrated with Slack to show immediate payment notifications.
Co-founder - Flarian
It’s very easy to keep things organized in channels with Slack.
Co-founder & CEO - AMPY
Some of our developers use Slack.
Co-founder & COO - TradingView
I really like Slack. The pricing is good. Sometimes it’s a challenge to keep up; you have to split your attention between so many communication tools. We have a dedicated channel for product feedback, and it works really well. I see how Slack can sometimes be distracting for your employees, but it is not our case. The only thing that I do not like is that it is not really easy to switch to a different team.
Founder - HandUp
Slack is the most common communication platform we use, and is essential for keeping our distributed office connected.
Senior Scientist - Applied Brain Research
We use Slack; I love it. You can organize everything in channels.
Co-founder - LivePoll
My team uses Slack--I personally find it confusing.
Founder & CEO - VIVE
We love Slack’s ability to integrate with Stripe, events, etc.
Founder - PeachDish
We have two Slack teams. Our employees are on the paid Standard version so that we have access to a searchable archive and unlimited integrations. We also have one for the community of coaches. This second one is free. It is amazing that with over 5000 coaches, we can communicate for free.
Founder & CEO - Coach.me
We use Slack because it is easy to use. It also has adjustable pricing; if someone on my team leaves, Slack takes care of automatically adjusting the price for it. Also, it separates the channels vs the chat rooms, which is a very convenient feature.
Founder - ZipBooks
We use a mix of Slack, Hangouts and Gmail for internal communication. We do all of our meetings in Google Hangouts. Other than that, we communicate in Slack.
Co-founder & CMO - DownToJam
When Slack got big, we jumped on the bandwagon. We were using Campfire, but Slack was better in every way.
Technical Founder - Campayn
Slack is good and it plugs into other tools. It’s good to upload documents to share and review.
Co-founder & CEO - WhereFor
Both these tools are good; they keep the tickets and they are not expensive.
Co-founder & Chief Product Architect - Koding
We use Slack heavily. Almost everything is done in Slack. We have bots integrated into it that help us do different things with it.
Co-founder & CEO - Impact Health
I feel a little lame saying we use Slack because everyone uses it. I like Slack; it’s a very fun application and it’s pretty simple. The flexibility to create channels is great too.
Co-founder & Head of Engineering - Flow Kana
We started a few years ago with Campfire, and then we moved to HipChat, which we had to pay for. But we liked HipChat so we were fine paying. Then Slack came out in 2014. It was free so we tried it out. We were early adopters of Slack, but we were planning on sticking with HipChat. But then it was like HipChat got scared of Slack, and then moved to being free. After HipChat went free--the service quality plummeted. It was slow, messages and connections would drop constantly. Over two weeks we lost all confidence in HipChat. So we moved to Slack, and it worked--which is probably the most important feature for a team communication tool.
Co-founder & CEO - Nitrous
We use Slack on a much smaller scale. It’s mainly used by our developers, or when we need special channels.
Co-founder & CEO - Venngage
We are collaborating with the Slack team to improve the functionality of Slack, but at this point for communication Slack is still not nearly as good as Skype.
Co-founder & CEO - Qordoba
We send most of our files to each other through drag and drop in Slack.
Co-founder & CEO - Doughbies
We love Slack, it’s awesome! It’s a lot of real-time chatting when everyone’s on it. It’s super robust now too. We use Slack as a channel for our brand, product design, everything.
Co-founder & CEO - Doughbies
Slack is very popular with the team.
Founder & CEO - Shortcut Labs
Slack is the main backbone of internal communication, and about 90% of group communication takes place on Slack. Most people are pretty happy with it. Some people building integrations with Slack have had some issues with the API, especially for deep integrations. But this is usually a function of heavy use, so doesn’t apply to everyone. Overall, we’re all pretty happy with it as a product.
CTO - Expa
The engineering team uses Slack.
Co-founder - Rocksbox
Slack is amazing, and they are customers of Concord so we like them a lot! It’s integrated with our own software, JIRA, and Intercom.
Co-founder & CEO - Concord
You need to set up the right notifications settings so it's not distracting, but after that, Slack is a fine communication tool.
Co-founder & CEO - Gorgias
We use Slack for group chat rooms.
Co-founder & CEO - PowerToFly
We’re really happy with Slack. We have it integrated with Stripe and PayPal, so as charges come in, they show up in Slack. We also have various Zapier zaps set up, so notifications from the website (e.g. leads and other activities) also show up in Slack.
Founder & CEO - Gigwell
We used to use HipChat, but we switched to Slack, and have never looked back!
Co-founder & COO - Branch Metrics
Slack is helpful because we have a GitHub API built in that keeps our engineering team updated on different push and pull requests. It’s usually helpful, but some team members have also found it distracting. It can pull them away from tasks they’re working on because so many notifications pop up. We’ve had to set up some timing rules so that people can sign out of Slack and focus exclusively on their tasks. It adds value and cleans up our inboxes, but there’s more room for improvement.
Co-founder & CEO - LeafLink
Slack is great for less salient, less critical issues, like water cooler banter, sharing links, interesting articles, and general observations.
Co-founder & CEO - Inkshares
We exclusively communicate through Slack. We used to have Slack integrated with Asana, but it wasn’t too useful. Every time someone would post a project, edit or add a comment in Asana, it would show up in Slack. Too much clutter showed up; it got too noisy. Slack has also been very good for our customer support since we’ve integrated it with Help Scout.
Co-founder - Bauxy
We used to use Slack, and we were actually beta users a few years ago. But we moved away from it because it created too much noise. We just want to get things shipped and done, and it’s important for us to not add extra noise to everything. We use Google Hangouts now. We’re already using Google Apps, and Hangouts is good for what we need.
Co-founder & CEO - DOZ
In general, the team likes Slack. But as a founder and executive, I feel that there’s not enough face-to-face collaboration when everyone relies on Slack. People feel like they’re already interacting in Slack, but I feel like people are really missing out on bigger brainstorming ideas when they’re only typing in Slack, especially since there’s only so much you can type! It’s always a 1:1 conversation in Slack, even if there are a number of people in the same channel; the most you can do is type 1:1 to each other, rather than have free-flowing brainstorming sessions with many people.
Founder & CEO - Wizeline
We love Slack! The whole company runs on it. I use and appreciate Slack. I think it's a great tool, and we’re always finding new and different ways to use it.
VP Marketing - Extole
Slack has been working out great. We use it differently than most companies because we use it more to stay on top of our technical structure (e.g. technical issue and bug tracking, FSH requests to deploy code) than for group chats. We’re still at the stage where email and text messaging work well for internal communication. I would recommend them because I don’t think anyone else lets you do what they allow your team to do.
Co-founder - Bubble
Slack’s good; I like it. Bugsnag and GitHub are integrated into Slack. Trello is integrated as well, so as tickets are updated or moved around, all of those notifications go into Slack.
Co-founder - BuildZoom
It feels like most everybody uses Slack. We have pretty good buy-in from the team, and Slack is something we rely on heavily at this point. We don’t have a ton of integrations, but we do have system reporting integrated with Slack. So when we’re doing a build, or when a build completes, we see a notification in Slack. And when we see a high rate of errors, we all see that reported in Slack.
Co-founder - FullContact
Slack has been great. It was the easiest to set up, especially in terms of company adoption and people being excited about using it.
Co-founder & COO - Club W
We offer private Slack channels for some of our enterprise clients.
Co-founder & CEO - Bold
We primarily use Slack. We have a bunch of integrations set up between Slack and other tools we use, like Pingdom and Intercom. One interesting use case we have is for our B2B clients that want it: we will set up a Slack channel just for them, which connects them directly to their Bold success team. This allows them to pop into Slack and reach us whenever they need.
Co-founder & CEO - Bold
We switched to Slack from HipChat about 9 months ago. It’s a fun tool, and really easy to use. More than anything, it seems that it’s trendy to be on Slack, and not necessarily because it’s better than something else. HipChat was fine, but part of the appeal of Slack was that it was the new thing. But more than that, it was appealing because we could try the free version. We were always paying for HipChat, so having access to Slack’s free version was what tipped the scales in its favor. We utilize free plans as much as possible for all of these tools.
COO - Chat Sports
We’re very active on Slack, and we love it. The only downside is that we have too many channels, so it can get a bit overwhelming at times.
Marketing Manager - Shippo
We tried Glip and HipChat, and while they were both great ideas in theory, in practice, neither one worked well. We’re on Slack now, but honestly, I don’t see the fuss about Slack. It’s not that user-friendly, and there’s usually too much going on in Slack. If I just want to ask someone a question, it makes it so complicated. Our team is ambivalent about it at this point. But there is a lot of active development on it, which is really good.
Founder & CEO - Good&Co
We love Slack! We just use it for group chat at this point. We hear stories of people using it in crazy ways, but we’re not at that point yet.
Co-founder & CEO - Neurotrack
We used to use email, but then we moved to Slack. We considered using HipChat, but we started using Slack, and one of our engineers really pushed for it, and it has worked out well. It’s a great product.
Co-founder & CEO - Townsquared
Earlier, when we were smaller, we were using WhatsApp to communicate with each other. But now we have more employees, and creating different WhatsApp groups for each team (Ops, Sales, Tech, etc.) was getting too messy. So we’ve since moved to Slack, and it’s going well.
Founder - JustDoc
For one-time use files, we share in Slack.
Co-founder & CEO - SpeakUp
Slack has replaced email and facilitated efficient, asynchronous communication for our team.
Co-founder & CEO - SpeakUp
We tried a few different tools, but Slack ended up being our favorite. We have different channels set up for different teams, and different GitHub repositories linked to Slack. For example, when there’s activity in GitHub, that Slack channel gets a notification. And we have Slack integrated with Sentry, so if our server is throwing an error, we’ll see a notification in Slack, and go to take a closer look. Datadog tracks performance metrics, so if the API is taking time to respond, we’ll get a notification in Slack.
Co-founder & CTO - URX
There are really only 2 or 3 tools that the entire company uses every day, and Slack would be the big one. Slack has created a cool paradigm shift on instant messaging, and it’s interesting the way they’ve put it together, and integrated with other applications. The way that the channels can be easily created, dismantled, or archived, allows for a really flexible workflow.
CEO - OnSIP
I’m a total Slack junkie! I’ve tried to push all internal communications to Slack. I continually keep reminding my team to not email me, and stop direct messaging me, so everything is kept in the correct channel. I love Slack, but their search feature is awful. And their native application for Mac has a weird user experience format. Menus are stacked on top of menus, and creating groups is terrible. And when and how you can use them is not clear. The groups will work in some places, and not others. The web app is much better than the Mac version, but if I didn’t use the desktop app, my Slack tab would be buried under the 200 other tabs I have open.
Founder - VentureOut
I love Slack! The only problem I have with Slack is that conversations get lost in translation. We have real conversations in Slack, but they’re mixed with the random conversations that occur concurrently, and people are constantly coming in and out of the channels. We’ve found that for some people, especially upper management, Slack can get too chatty to hold people accountable. Our solution to making sure people are not missing important conversations is to say that anything that is urgent or high priority must be emailed. And general chatting stays in Slack.
Founder & CEO - FORTE
We use the pro version of Slack. The free version is good, but it doesn’t store messages. We have different channels set up for all of our different teams, like marketing, engineering, etc. It’s a big resource for us, and eliminates the need for tons of emails on a daily basis.
Co-founder & CEO - Blue Bite
We’re continuing to change how we use Slack, and we’re constantly adding more notifier Slackbots, so everyone can get notifications when someone mentions them, etc. But while we’re constantly adding to it, we are being mindful of keeping it as simple as possible at the same time. Our 2 main integrations with Slack are Giphy and Google Docs.
Founder & CEO - Insurify
WE LOVE SLACK! We’re pretty much just using it for internal communications, but do quite a bit of project management through it.
Founder & CEO - Arment Dietrich
We’re pretty much just using Slack for internal communications, but do quite a bit of project management through it. I have a channel called “Docs for Gini to Review” and everything goes in there so it’s easy for me to track.
Founder & CEO - Arment Dietrich
Slack is great.
Founder & CEO - Skout Deals
One of coolest uses of Slack we’ve discovered is for tweeting and retweeting for social media exposure. Anything shared on Twitter by our alumni is posted in a Slack channel. So when someone tweets something relevant, and they want us to retweet it, they just put it in that Slack channel and everyone that sees it will retweet it.
Co-founder & Co-director - Boomtown Accelerator
We use Slack for internal communication. We have a lot of tools integrated with Slack, like GitHub.
Founder & CEO - Roomi
We use Slack, and we love it. We have it integrated with our application tracking system. We have rounds and rounds of deadlines for our fellowship program, and we can see everything updated in real-time, like the number of applications submitted, all in Slack. We have so many Fellows we keep track of, and everything is integrated with Salesforce, which is also integrated with Slack. So if a Fellow’s contact information or job changes, that Slack channel sends us a notification. This is all really important information for us to have when we go out and speak to people; knowing where people are moving, in which city they’re in currently, etc. is critical. We try to keep everyone up to date as possible, and Slack has helped immensely with this.
COO - Venture for America
We’re big fans of Slack! We’ve connected various tools to it, and have channels for everything from Trello to GitHub to our internal KPIs. And of course, we’re big fans of the GIPHY integration!
Head of Marketing - Pipedrive
Slack has helped cut down on the clutter in our inboxes. And our “Random” channel has been good for cutting down on random chatter that was crowding our Slack conversations. I would highly recommend having a “Random” channel if you’re using Slack.
Founder & CEO - Museum Hack
It’s hard to get everyone on the same tool, especially when not everyone is a full-time employee, so we use whatever our employees want to use. We use Slack at our WeWork co-working space. When we have an event, we’ll put a notice out to everyone in Slack.
Co-founder - Monarq
We use Slack religiously, and we’re obsessed.
Founder & CEO - VProud
We enjoy using Slack for interoffice communications. It’s not necessarily like a dashboard, but any major events are reported into a Slack channel. For example, when a user signs up, we see that in a channel, or when there is a FullStory recording, we see that in a channel. Support tickets go into the Intercom channel, and GitHub reports trigger notifications as well. Slack is a very convenient way to stay informed, and I really like their desktop notifications.
Co-founder & CEO - Rollout.io
We tried both Slack and Glip, but neither one caught on with the team. I hear people singing odes to how wonderful Slack is, but I didn’t really see it adding a huge amount of value over and above Google. I’m definitely open to being proved wrong though...
Co-founder & CEO - Priori Legal
We’re very active on Slack, especially because we don’t have an office. Having lots of different channels has been a good way to organize everything.
Co-founder - Croissant
We mainly use Slack and Google Hangouts for video chat. Slack has great integrations. We have it integrated with GitHub. Integration with GitHub is simple and it tells you which project, what type of alerts, and if somebody is pushing anything. We have a commit log within Slack, so even when we do remote work, we just push notifications in Slack. The main downside is that we have other organization groups and I would like if there was one single login instead of separate ones for each group. It’s annoying to login every time for the different groups.
Co-founder & CTO - Tutorlist
We used to use HipChat, but switched to Slack. Slack’s been very good. We haven’t hit our limit yet, and we’re hoping to maintain our <10,000 messages/month usage numbers, so we can stay on the free plan! We have quite a few webhooks and integrations setup with Slack, with our testing software, Trello, JIRA, social media, etc. Anything we need to pay attention to, we’ve integrated with Slack so we can see notifications all in one place.
Founder & CEO - Brick & Portal
We do a little bit of file sharing on Slack.
I’m on a podcast, and my co-hosts and I use Slack to collaborate, research, and plan our shows. We’ll pin things, share links, and have discussions about upcoming shows. It’s really great. I also like Slack because we all have so many platforms, and we’re connected to so many people, Slack’s closer to being an all-in-one communications app than any other. 15 years ago, we relied on phones and emails, but now you can find, and connect with, people a million different ways. I would still love an all-in-one app, which used to be email, but Slack is the closest thing now.
I sometimes use Slack for project management. It’s not really a project management tool, but I find you can organize projects by channel. For simple projects, Slack has a lot of great features.
We use both Slack and Skype a lot. For group chats, we use Slack.
Founder & CEO - Social Data Collective
We were using Slack, and had high hopes that it would help us with project management. It seems fantastic, but we couldn’t get buy-in from the team. I really wish Slack had better training tools, since that would definitely help with team buy-in. Taking a webinar is not the same as getting a live training. Implementing it and getting everyone to jump in is hard.
Founder & CEO - Creative Business Inc.
The biggest pain point we have as a company is that we have a distributed team spread out across the country. We use Slack to help ease this pain point. We used HipChat for a long time and then switched over to Slack last year. We use it like everyone else uses it; as a constant background stream of communication. One of the things about Slack that is a blessing and curse is that it makes communication so easy. This can be a curse because it makes it hard to focus, with so much going on, and notifications going off all the time. One of the things we learned with RescueTime data is that communication eats up a large amount of people’s time. Slack is touted as a way to stop using email, but our data shows that people are often spending just as much time, if not more, in Slack! We have tools in RescueTime to help people focus, and if you have it linked to your Slack account, it will mute notifications, mark you as away, etc. Everything gets pushed off to the background for a little bit. When I first turned it on, it was a novelty, but now I rely on it to help me focus. It allows me to have easy access to communication when I want it, but when I don’t, it all goes away.
VP of Product Development - RescueTime
We use Slack for free, and use it for basic chat only. We’re not doing anything crazy in it at this point.
Founder & CEO - Reactful
Slack’s been great. It has definitely helped us cut down on emails, and most of our internal communications occur via Slack now. While we love Slack, it does get noisy at times. We’re currently working on an integration between our product and Slack, and working with Slack has been great.
Founder & CEO - Knowtify
We like using Slack. We have group chats and different channels set up by subject. We also have integrations set up with customer support ticketing, dev ops, etc. We have alerts set up in Slack, so if something happens, the alerts show up in Slack, and are pushed to the appropriate team members’ cell phones as well.
Founder & CEO - Shoppimon
We like Skype more than Slack because to enable calls in Slack, you have to integrate it with something else, whereas that’s already embedded in Skype. We’ve tried using Slack 3 times, and it’s always so confusing to know the difference between groups and channels. It got frustrating never knowing where things would appear.
Co-founder & CEO - Comeet
We started out using HipChat initially, and then we switched to Slack. Slack’s a wonderful tool, but their search function is absolutely horrible! The search criteria is bad, even the location of the search box is bad. We love the tool, and we’re paying for it; it’s a nifty communication tool overall. But beware that anything that happened more than a week ago is totally lost! You can’t search for anything in Slack. We’ve been trained on Google for so long, our expectations for search are so high, and Slack does not even come close to meeting our expectations.
CEO & Founder - x.ai
We are keeping Slack simple for now and only using it for group chats.
Co-founder - BuzzStream
For collaboration, we use Slack. Overall, we’re happy with Slack, and it has a better UI and is more fun to use than HipChat, which we used in the past. For us, there isn’t a huge difference between HipChat and Slack, but there is a major feature missing in Slack. In HipChat, you can paste a JIRA issue in, and HipChat will show you the full issue. No one has to leave HipChat to go see the full issue. We miss that capability, and it may be the reason we move back to HipChat, if we do decide to switch back. But for right now, people are enjoying using Slack more than HipChat, so that’s outweighing missing the JIRA feature.
Co-founder - BuzzStream
Slack is great. We basically don’t email each other anymore, and just message each other on Slack. Hopefully, it will stay organized, even 3-4 years from now, and not turn into a big mess like email is now. We have Slack integrated with a few services like Trello, Mention, Intercom, Google Docs, and some server events, which is extremely helpful.
Co-founder & CEO - Veed.Me
Everyone loves Slack, and we haven’t experienced any big downsides with using them. When the sales team makes a sale, a notification pops up in that Slack channel. We also have Slack integrated with Airbrake, so errors show up in Slack, and when we commit code on GitHub, those show up in Slack as well.
Founder & CEO - Justworks
Slack is our main internal communication tool, but we use a number of other tools as well. Different people and teams use each tool differently, but for the most part, we use Slack for more client-specific chats with the team and for brainstorming.
Co-founder & CEO - Sociality Squared
We used to use HipChat, and we switched to Slack for no other reason than because everyone was talking about it, so we wanted to try it. We didn’t immediately see how it was much better than HipChat, but it works nicely, and it does look better than HipChat. The emoji reactions is a brilliant little feature, and on the Mac client, there are subtle things that set it apart, like being able to switch between teams easily. Slack also gives you the ability to have single-channel guests, which is nice. We created a channel for a design project and invited one of our angel investors to the channel to get advice on design, and we were able to add him to the channel without having to add him as a user on our account. In the beginning, we didn’t feel like we needed lots of channels, so we just used the #general and #random channels that they start you off with. But I spoke with a friend who works at Slack and he said they use product-specific channels. We realized that channels can be lightweight and short-lived. When we just had one #general channel, it was really hard to have multiple conversations at once, since there are no threaded conversations. But we learned that if you open a separate channel for a project or feature, you can post the spec in there, discuss it, and any questions can go in that specific channel. This has helped us keeps things organized, and once we started doing that, it helped our communications.
Co-founder & CEO - Fieldbook
We’re heavy Slack users, and big on building our own apps on top of Slack. We’re getting into machine to human messaging on Slack, which is very exciting. The biggest downside of using Slack is that the freemium package allows us to only search a limited amount of messages. You really begin to feel the heat of this after you pass 1000 messages, and then when you try to search for a message, it feels like everything is lost. At this point, we make sure to keep important messages in email so we don’t lose them in Slack.
Co-founder & CTO - Spree
We use Slack because it’s free, and everybody uses it. For the best collaboration, I truly believe that you have to be using what everyone is using, which at this point, is Slack. In the early days, when Slack was just emerging, I discovered (like many a tech CEO) that many on my team were using it without my knowledge. So, I just went with the flow and standardized on it. Since then, we’ve gone all-in with it. We’ve written our own internal applications to integrate with it. We’ve already integrated our GitHub deployment and pull requests, track our Twitter mentions, daily standups, and some customer alerting, all in Slack. We’re also currently on the verge of releasing a product, and one of the innovations of this product is that our cloud provisioner can be accessed with a Slack command line interface.
Founder - Qbox
Slack has replaced Asana for us, and we use Slack for every project. For example, if we’re redesigning our home page, everyone working on that project is in that project’s Slack channel while working on it. All mockups, comments and thoughts about that project all go into Slack. It’s much more efficient than having six meetings a week about a project. With Slack, we just have one meeting, and then discuss the rest on Slack. Slack also has a basic file management system, which we use as well.
CEO - Zumper
Slack is great, and we really love it. We’ve only recently started using Slack, but we have ambitions to use it for more than just group chats, such as for customer service, and maybe even expanding it beyond just our team to allow members to chat with us as well.
Managing Director - Impact Hub NYC
We’re mainly using Slack for group chats and collaborating on projects. And Calamari is integrated with Slack, so that’s a huge plus.
Co-founder - Chrobrus
We are Slack addicts, like everyone else. All of our teams use it, and we use it mostly for sending giphys.
Co-founder - TheSquareFoot
We use Slack mainly for group chats, as well as sending and sharing links. It’s great for making sure people who aren’t in the office are still a part of all of our conversations. We like it so far, and it’s the only tool that I’m married to at this point.
Founder & CEO - Dibs
We switched to Slack from HipChat because everyone was hyping it up like crazy. When we told people we were using HipChat, people said, “You have to use Slack. It’s amazing.” From what they described, I didn’t understand what made it so amazing, since it sounded exactly like HipChat! But everyone at our company pushed aggressively for us to switch, and I wasn’t going to fight it if they really wanted to. And the migration from HipChat to Slack has been really easy. We just exported messages from HipChat to Slack. Integrations are a bit smoother with Slack, and the integrations with GitHub and Asana are really cool. Someone can create a task in Asana and we can set it up to message all of us automatically in Slack. And when the developers make commits in GitHub, it shows up in Slack. We don’t have to log into 20 different platforms, which is helpful. Slack is good, but in the end, it really feels like just the same thing as HipChat! The benefits from Slack and HipChat have been huge for us so far. As your team grows, these systems allow you to easily organize and provide a much quicker turnaround than email. And you can leave your team for meetings and come back and read all of the conversations that happened while you were out. They provide you with a transcript of everything that is happening in your company, so you don’t miss out on anything. And from a managerial perspective, it’s super awesome to have a system like Slack or HipChat. Having systems like this surprisingly lead to team communications being much more friendly, with things like emojis, personal avatars, and encouraging image-sharing, etc. You wouldn’t think it’s a big deal, but adding friendliness to daily communications is huge.
Co-founder - Kinnek
I love Slack. The most important integration we have is a food truck park next to our office; Slack pulls in the list of trucks are going to be there each day, so we know exactly what our lunch options will be. We also integrate Slack with GitHub and Help Scout: Whenever we get a new Help Scout customer service request, it shows up automatically in Slack.
Founder & CEO - CoinTent
Slack is the best. We create channels for every client we have. So if we need a quick response, we try to not clog each other’s email inboxes. We have it integrated with Google Drive, too.
Co-founder & CEO - Truman James
In Slack, we create channels for each customer.
Co-founder & CEO - Truman James
We have a team of 20 spread across the country, so Slack is very useful. We were using Google Hangouts and Skype for a while, but Slack has taken over all of that, like it seems it has has for everyone. It’s just a better messaging system-it’s well-built and simple. We tried to schedule meetings through Slack, but we’re a bunch of salespeople and it didn’t work for us. I’ve heard that it works really well for engineers and development teams, and integrates nicely with programs like Trello, etc., but we haven’t done that or needed it.
Founder & CEO - Venwise
We love Slack. We have it hooked up to Stripe, so whenever a payment comes in, we can all see it. And anytime a candidate or startup applies, we get a notification in a Slack channel. The candidate channel is really noisy (it’s too much for some people), but I really like it. We also built our own Trello integration, which is great for project management purposes. We’re currently considering using Slack to interact with our customers. This would enable us to chat with our customers at any given time, but we haven’t done it yet.
Co-founder - Underdog.io
Slack is consistently a great app, especially for a company with teams across geographies. It’s been a real life-saver for us. We integrate a lot of tools into it (Salesforce, Twitter, social feed, proprietary backend systems), and it’s our first stop for all internal information. I’d say it has significantly reduced the amount of emailing we do internally.
Co-founder & CEO - PivotDesk
Slack has been good. It’s a good intermediary communication system if you don’t want to get up and walk over to talk to somebody. Our entire team is in the same office, so we don’t have a huge need for an internal communication system, nor do we have to worry about coordinating with people in different time zones. We have some integrations with Slack, like Giphy, but nothing too serious. They’re all for fun stuff inside the chat rooms.
Head of Finance - Dots
We have people in Philadelphia, New York and San Francisco, so we can keep in touch easily because of Slack and Dasher. Slack is for company conversations. What’s great is that Dash also integrates with Slack. When someone on our team asks for approval for funds, it’ll ring on all of our phones via text, email and Slack. There is no way to miss the alerts to approve funds. We’re definitely liking it. We’re still trying to figure out the best video conferencing platform, but Slack helps us stay in touch.
Senior VP Communications & Marketing - Karmic Labs
We’ve been using Slack for the last 6-8 months. Before that, we used Google Chat, since we’re on Google email already. But Slack has been great because it allows us to have different channels set up for different conversations, depending on which product is being discussed. It’s very easy to keep all of our channels separate and organized. And it’s very easy to add files into what we’re talking about. We have a developer in Taiwan, some of our team is in New York and some are in California, so it’s really helpful to have Slack available on all of our phones and computers.
Founder & CEO - Blinkbuggy
We use Slack almost as much as Google Drive to share files with each other.
As the nontechnical co-founder, it’s nice to watch, and helpful to see, everything in Slack. It was especially helpful before we got our own office. Slack is good because you can integrate it with a ton of programs. For example, my calendar appointments pop up in Slack, so everyone knows what I’m doing during the day. They’re really trying to make it a very powerful tool.
This is an interesting category for us. We’re basically a bunch of hackers, so we all manage ourselves. We use GitHub, Trello and Slack all together. We use Slack for communicating with each other, and we have GitHub integrated with Slack, so we can all see who is working on what, and all commits to the code base show up in Slack.
We have JIRA and Intercom integrated into Slack. We get Intercom notifications in Slack, and are able to respond quickly. Everyone sees when a customer starts up a chat, and we can all see who responds first, and see who has already responded. We used to use Telegram, and they were great, but they do not have as many features as Slack.
Co-founder - Simple Texting
Our whole office is on Slack. Most of the team loves it, but it can be a challenge for the people who live all day on their email: the marketing and business development folks. Our tech and product teams--who love it for all of its bot and service integrations, and who do "ChatOps," which is deploying code and managing infrastructure through a chat room--would love to see it embraced more by the marketing/biz dev teams, but for those teams, Slack is just another platform for them to monitor because they’re getting so many emails from clients. Even for non-tech folks, though, Slack is great because it gives them a better understanding of what’s going on on the tech side, where they would otherwise have little insight. We also appreciate that Slack adds new integrations all the time based on customer feedback.
CEO - DoSomething
We used to use Slack, but we’ve since stopped. All of our internal communications are done via Gmail now. I hated Slack. It got really confusing, and when you went to reference something, like documents sent over Slack, it was a total pain. In Gmail, if I send something to someone, when I need to reference it, I just type a keyword into the search box and it pops up. When we tried to do that with Slack, it didn’t work. It was not user-friendly, and there were so many channels and categories, it got very overwhelming, and people would mix up conversations, etc. We also just walk over to one another and talk to each other if we need to communicate!
Chief Operations Officer - CTRL Collective
Our team is remote, so Slack is where we spend all of our time. We have all of our development tools integrated into Slack channels. In Slack, we basically have a firehose of all notifications for everything for development, including exceptions and commits. We also use it to keep track of all social chatter. So if anyone mentions us or uses our hashtags, it all goes into a channel. We also have Slack integrated with Intercom for customer support tracking, so when a customer emails support or signs up, we automatically have a notification in Slack. It gets noisy and busy, but it gives us good visibility into what’s happening with our company. The daily email digests show us great stats like how many people signed up yesterday. We also have single private channel support where we provide 1:1 support to customers from Slack. We currently have Slack integrated with Google Hangouts, Intercom and Zapier.
Founder & Head of Operations - Wheelhouse
Everyone on our team uses Slack. Between that and Google Docs, everything is in there.
Co-founder & CIO - Enplug
We make heavy use of integrations with Slack. We have an activity channel that shows a live stream of Zendesk customer issues and GitHub commits. It gives us a place to go for a quick glance to see trends. We can also see any Tweets that mention us. We also have a cancellations channel to track churn. If someone pauses or cancels with us, that information goes to this channel, along with why they’re pausing or canceling, and any feedback from them. We have a competitor info channel, which shows articles or PR about the industry. And we have a customer feedback channel. We have channels for every department. There haven’t been any cons so far; it’s really excellent. We were on the free tier, and upgraded to the paid version to get access to the search feature. It’s been totally worth it.
Co-founder & CIO - Enplug
We love Slack--we think it’s awesome. It has definitely made things easier for our team, especially since we’re in two different locations. We have a couple of automated functions set up in Slack. We have a channel to see all payments and orders coming in. Our operations processes also trigger Slack notifications at integral points. For instance, when an order is placed, an invoice is paid or a proof is approved, an automated message is triggered to the correct channel in Slack. It’s a nice way keep the flow of orders going, and see how well you’re doing during the day. We also have certain commands set up in Slack that report out daily revenue, for example. It’s a fun way to track, and the Giphy integration is hilarious! Overall, Slack makes communication more streamlined and more enjoyable.
CEO & Co-founder - Plum Print
We use Slack to work on projects. It’s a great way for our team to communicate, especially since we don’t all live in the same place. We use it mainly for chats, but we do use it for file sharing, in tandem with Google Docs. We have about 15 different channels in there, including an Intercom integration. And our tech team has Sentry, our bug reporter, in there.
Co-founder & COO - RealLife Global
We have Slack pulling in a number of RSS feeds from the website. Every time a new person registers, that information is pulled into our Slack channel for new clients, with all of their information populated automatically into Slack. We don’t have anything too crazy set up in Slack; mainly RSS feeds and Twitter getting pulled into it.
CMO & EVP of Sales - ExecRank
We use Slack, but we’ve really fallen off with using it. It’s really hard to transition away from email to Slack. You have to commit as a company to the notion that this is how you’re communicating now. We have different channels set up like a business development channel that shows, “This person had a meeting with this person,”and others can respond and comment, which is nice. But so much of our communication is with external people that aren’t on Slack, so it’s hard. If I get an email from someone outside of our company, I have to forward it to Slack, then we can comment on it in Slack. It adds extra steps. When we’re in a different stage, and we’re bigger and more established, I can see using Slack more than email, since email will be quite unwieldy. And sometimes I do want to switch to something else since Gmail’s threaded emails make email less appealing.
Co-founder - GoKid
Slack has been able to replace a lot of email. Email is such a full channel, and usually full of garbage. We have a central Slack channel that we all use to to talk to each other. We’re really happy with it and, so far, no cons. We have no other tools integrated with Slack. We’re all about integrations, but people are moving more and more toward limiting themselves to as few tools as possible. So we’d rather have Slack do more, than have more software integrated with Slack.
CEO & Founder - DK New Media
Our engineers drove the adoption of Slack early on, and we've fully embraced it. Custom emojis are used heavily at Zola – we have one for Jake Gyllenhaal sightings at La Colombe and sweetgreen icons for lunch requests. We also love the integrations into Zendesk, New Relic, Dropbox, etc.
Chief Design Officer & Co-founder - Zola
We use Slack, not Skype anymore, for video.
Founder & CEO - Codementor
We use Slack mainly for team chats, with different channels like general, code check-ins and private messaging between team members. We like it. We switched off of an open source product, and we’re happy. We share documents in Slack occasionally, but it’s really for chats. We have Beanstalk and Pingdom integrations with Slack, and I’m testing a hook-up to Zapier, but haven’t used it much yet.
Founder & CMO - Cloze
We’re big fans of Slack. Before Slack, we used Skype, Google Hangouts, text and email. Slack has been a much better system for internal communication between our different groups that doesn’t burden our inboxes. The only con we’ve experienced is integration issues with Google Hangouts.
Founder & CEO - Nomad Financial
I absolutely despise Slack. It’s the worst thing ever. Just send me an email! Slack should not be used for the entire team; it should just be used as a development tool. I know the developers love it because they hate email, and I totally understand that. But everyone else should not be using it; there’s no reason we should be discussing and negotiating contract terms in a chat room.
CFO - Makeable
There are four of us in NYC and the rest are remote, and Slack works really well for us. We integrate it with Trello, and when we do team exercises, we use Slack in conjunction with the call. I feel like if Slack had video on its free version, or if Skype had a better chat function, they could just knock each other out.
Co-founder & CEO - BarterSugar
We use Slack for dealing with customer issues directly.
Slack is my favorite tool in the entire world. It’s also a really good project management tool--we integrate it with Trello now, and will be integrating it with Salesforce once we have that system set up. We have hundreds of channels set up now. Every play we do has its own channel. What’s really great about Slack is that, not only is it easy to use, intuitive, great for sharing, etc, but it essentially journals the history of decisions you’ve made and things that transacted. It’s easy to export that info into your company playbook, which is really what growing companies need. Slack helps you keep track of what works and doesn’t work. Slack is also obviously really good at chat, and we’re big on communication. Having a good company means you can communicate fluidly with your customers so that you can fix what needs to be fixed and build things that they want. And it gives users real-time information on how to innovate and build your business. Slack is one of the most important tools that we use as an organization.
We tried to use Slack, but I got the feeling that they didn’t care if I was using their app or not. They basically just said, “Hey, here’s this cool thing. Read all the cool things people are saying about us. If you’re cool, use us, if not, buzz off."
Founder & CEO - Halo Life Science
Slack is our go-to communication tool. We use it for everything from company teams to customer service to Mention-wide chat and more.
Head of Growth Marketing (former) - Mention
Slack integrates well with other tools, and its interface is better and smoother than HipChat. The neat thing about Slack is that, whenever my developer pushes something out to the code repository, or when one of our publishers pushes a blog post, we get alerts on Slack. The integrations are really useful. Slack is great when you want to interrupt someone, but when you get interrupted, it’s annoying. You have to keep it open all day, so I normally switch it off when I’m trying to focus. If I’m doing something casual and can be interrupted, I turn it back on. I don’t agree with people who say Slack can replace email. I like email because I can check it on my own time, and the conversation is neat and all in one place. Slack makes this information a mess, even if you use the separate channels. It’s good if you need something urgent, but if it’s something that can wait, I use email because i don’t want to interrupt them.
Founder - Brightpod
We love Slack. It’s extremely robust, and we have no complaints. It’s great for real-time and asynchronous conversations. It’s been a nice way to stay connected, even for a fully remote company. We set it up from the beginning to allow us all to be remote.
Co-founder - Quill
We use Slack. All internal communications--from what we all want for lunch to bug fixes--live in Slack. What’s funny is that it’s not an original idea, as programs like IRC have been around for a long time, but Slack puts it all into a great-looking package that is also fun and enjoyable to use.
Co-founder - Aviary
We don’t actually do much with social media. We have a channel in Slack that pulls Twitter mentions with our names and our company name in one place. And then we’ll log directly into Twitter to respond.
Founder & COO - Book In A Box
99% of our internal communications happen on Slack. There’s just nothing else that compares to it. I have used other team chat software before, and I hated all of them. There’s something about Slack that makes you want to use it. It makes it feel like we all work in one office together, and like we all know each other well. It seems they’ve tapped into some way of psychologically making us want to use it. We have Slack broken down into different channels, made up of different groups of people that need to be communicating with each other. We also have a channel for daily intentions and check-ins.
Founder & COO - Book In A Box
We like the general vibe of Slack. Prior to Slack, we had people texting, emailing, talking to each other in a whole bunch of different ways, so consolidating all communication under Slack was great. My favorite part about Slack is all of its integrations.
Founder - SenseHealth
We love Slack’s integrations with third parties, such as Heroku, GitHub, Wercker and others that allow us to know the status of a project.
COO, Developer - Lightmatter
The development team uses Slack because they are the only team spread out across different cities. The user support team works together in person, so they do not need an internal communication tool at this point. Right now, the only overlap is that the head of user support has been invited to Slack to see bug tracking and bug fixing information, just so he has a heads up about what’s being identified, and he can tell users when certain bugs will be fixed. My partner, the CTO, actually complains a lot about Slack because it doesn’t render code properly.
Co-founder - Claim It!
Most of the tools we have are plugged into Slack. For instance, whenever there's a ticket that lands in HelpScout, it's sent to that dedicated Slack channel. The surveys we send out through Typeform or ClickInsightsIO all land in a Slack channel. So it really works as a hub for all the notifications from the other tools we use.
Co-founder - Cloudo
At this point, duh.
CEO - Katch
Our company would not exist without Slack.
Co-founder & COO - Casper
We use Slack for daily and weekly reporting. Every morning, everyone says what they are working on, and every night, everybody reports back what they’ve done. All of us work from home, so it’s like a virtual standup meeting.
Founder & CEO - UnifiedVU
This has become the go-to communication tool that our teams use.
Co-founder & COO - Betterment
Slack is God. It’s just really good. The features like emoji reactions make it fun, and make it feel different than email. As an editor, it’s nice to be able to put a checkmark icon on the conversation. And you can view conversations as a thread or a stream, and I like that. If you have a file, and you start comments on the file, what Slack does is it puts those comments in the stream, but they’re also attached as a thread attached to the file. If people are chatting in streams, you can follow the unified stream, or follow the thread. Slack has done a really great job figuring out the nuances of conversation.
Editorial Director & Editor-in-Chief - ReadWrite
Slack is incredible. It has helped us significantly cut the number of internal emails, speed up communication and make critical information more manageable.
Co-founder & CEO - sli.do
We use Slack when trying to get quick feedback on documents ready to ship. Again, being able to “favorite” them is awesome. Slack keeps file favorites separate from message favorites, which makes it easy to find what you’re looking for.
We love Slack!
In Slack, you can “star” messages, which makes them super-easy to refer back to. Sometimes someone will propose a plan for the next month as a simple Slack message, and if everyone’s on board, that Slack chat is the record of the decision.
Slack offers a superior method of communication.
Partner - DXagency
Slack is great. It has helped reduce some of our overhead emails, and it makes it easy to have internal discussions and share knowledge. This is especially helpful since we have offices and partners all over the world, and many remote employees.
Managing Director of VPaaS, Ecosystem and Community - Kaltura
We love Slack. The only thing I don’t love is that, until you pay, they cap your archive-accessible messages at 10,000 messages, which is really inconsistent with the values of our eco-system. They're literally holding your data hostage. There are lots of other well-established freemium models out there that they could be using. Slack is the darling of the tech world at the moment, and I think that’s really whitewashed what is fundamentally a dark conversion tactic.
CEO - Fluent City
Slack allows you to set up separate channels as necessary for your teams, so you can have rooms devoted to various departments, projects, etc. It's both a desktop and mobile app. The chat function is good, and it’s great for messaging my team one-liners and asking quick questions about various products. But it's most helpful in serving as a newsfeed between your different systems (Trello, GitHub, Twitter--they integrate with every major service a startup would need). It's also great for file sharing and searching, and I've seen some larger teams use it, too. I can't fathom not using Slack and going back to email.
Co-founder - Point
We love Slack--there's no one our team who doesn't. It's just fantastic. We actually don't pay for it yet because we still fit into their free plan. We don't concern ourselves with their data.
Co-founder & President - ALICE
I really like Slack, and their customer service is great. Prior to Slack we used Google Chat and regular chat services.
CTO, COO - Parrable
Slack is pretty good. We still wind up using Google Hangouts a bit, and we have designers talking on appear.in. Slack is keeping track of everything, which is great, but if the job that it's supposed to be doing is keeping everything in one place, it doesn't. We just started paying for it, and I'm not sure I'm getting full value from it yet.

Slack is amazing! It saves from having to send internal email. We love the immediacy of it.
Founder & CEO - Kontor
I (also) use Slack to communicate with other ed-tech companies and founders. When we grow, we'll probably switch to Slack.
CEO - DeansList
We've been happy with Slack. I like the basic simplicity of the integration with all of our other tools, which makes it much more malleable in terms of opening it up and logging in every day-- everything is in one spot. The log-in process is a bit annoying, but that's my only complaint.
Founder & CEO - NextGenVest
Slack has been wonderful. We were a really early user of Slack, and once we distributed our workforce across multiple time zones, it became really integral. It’s super lightweight, but allows us all to get out of email and stay in touch. It gives people the ambient noise and pulse of the company without actually having to be there.
CEO & Co-founder - Movable Ink
I'm not entirely sure because I don't use it that much personally ... but in my mind it just adds to the chaos, rather than detracting from it.
Founder & CEO - Founder Shield
Without question, Slack is the right choice for internal communication. The dedicated desktop and mobile apps are top-notch, and the features are robust. To top it all off, Slack has an incredible slew of integrations available: GitHub, Trello, MailChimp, Groove and many more.
Co-founder & COO - Castle
Together, Google Drive and Slack create a powerful solution that’s easy to use and seamlessly integrates with Gmail.

Slack is just a really good, solid product.
Co-founder & CEO - Zapier
I really like Slack. We used HipChat earlier on, but had some friends who showed me Slack instead. It's so much sleeker and easier to navigate. It hardly cost us anything to make the change, so we switched over, and we've been very happy with it.
Co-founder - BananaDesk
We're all pretty remote at this point, so Slack is the only real way to collaborate. We use Instabug and JIRA for development, and we keep a tech-ops channel in Slack that we talk through. Slack’s integrations are really great. For instance, I'll get Slack updates from JIRA, and vice versa. It's nice because it also has a lot of PowerPoint-type presentation functions, so we make a lot of our important decisions in Slack.
CEO - Truffle
I love everything about Slack. They work great and have great price points.
CEO - Splash
It's good. I personally don't use it as much as our engineers. They love it and have stopped using Google Chat entirely.
CEO - Canopy Apps
We love Slack, and we were one of their earliest adopters. We use Slack channels for our different product teams and for customer issues.
Founder & CEO - Layer
Obviously I’m a fan. But as somebody who’s pretty obsessed with my own and my team’s productivity, I’m pretty frustrated by it. I think it solves a lot of big problems (like getting people out of unnecessary email threads) in a beautiful, easy-to-use, intuitive way--that part’s great. But at the same time, it becomes a constant interruption with no real way to hit pause and come back to it when needed. There are a lot of simple improvements that would allow people to control it more, like being able to go idle, adding filtering capabilities, or implementing smarter notifications, etc. You can’t even mark a message “unread” on your desktop. With email, you can make it serve you instead of you serving it, but Slack is missing those user controls—instead, it’s a nonstop feed that you feel like you have to constantly watch and respond to immediately. I expect they’ll implement these features over time, but I’d rather they get here sooner than later!
CEO & Founder - Greatist
We have Slack, but most of us still use email, as it’s hard to switch away from that.
Founder & CEO - Zeel
Slack is a neat communication tool that allows the entire organization to collaborate without a Skype username. It offers the best way to globally and quickly communicate. We’re currently using the free version but are in the process of evaluating upgrade options.
Founder & CEO - Kargo
We use Slack for group messaging, and we communicate through it on a day-to-day basis. We have channels for each group and office, and you can use direct messaging in there, too. We really like it because you can search through all past history, and there’s a lot of integration that's really helpful. Any time we get a sale, it shows up automatically in a Slack chatroom.
Co-founder & CEO - One Month
Even though we have a small team, we use Slack for our app beta testers. We recently moved to the paid plan. But their free plan was still awesome. You can upload custom emojis which is probably my favorite feature. Slack is surprisingly entertaining, even though it's really functional. It adds whimsy to daily work.
Founder & President - Lionheart Software
We've implemented Slack, but it's not really the right fit for our employees right now. Most of our employees are out on the street or at work sites all day, and Slack's chat application seems to work best when people are at their desks all day. We just don't have that type of company right now. As we build more of a product/engineer culture, which we will as we grow, Slack will be more useful. But for now, we mostly just text back and forth.
Founder & CEO - Common Living Inc.
... Slack is so good at understanding when to change push notifications from the desktop to the phone. Somehow, it knows when you've left your computer, which is huge for me.
Co-founder and CEO - Fantasmo Studios
We started using Slack in the Spring, and it has quickly become our internal communication tool of choice, replacing email. We use it for both direct communications and group communications around particular game projects.
CEO - TreSensa
Slack’s functionality is not very different than some of the other communication tools, but they've definitely spent a lot of time pulling it together and making sure the integrations go really well with Google, Trello or whatever else you use. Everything just flows together with one click, so it becomes a really smooth interface to use for everything you have to do--attachments, sharing files, screens, videos, etc. There's a reason they're growing so fast.
Founder & CEO - Tinkergarten
Slack is great, and we’re still on the free account. We have six external contractors and a couple more partners who work with us. The rooms are great--it's easy to give everyone an account and they can get caught up.
Founding Partner, Chief Product Officer - Reboot
I love it, especially the iPhone and Android integration. When someone is working over the weekend and they have a tech question, it's so easy to check back, and when you're really "out of the office," you can turn the notification off. Slack as a service is pretty basic. It's just a text and chat room. We only use a few channels. We can see changes across our entire source code from different ventures and different projects. It just keeps you in the know.
