224 Slack communities that will give you superpowers

Who knew there were so many awesome Slack communities to check out? We've found 224 of the best (yes, that's not a mistake). Jump in and start soaking up the Slack goodness!

With over 5 million daily active users, Slack is a powerhouse. With numbers like that, it’s more than likely that if you work in a startup or tech you have the little criss-crossed logo booted up whenever you’re working.

Along with the work-related teams, some of you will have some other relevant communities you’re hooked on. To anyone who is only making an appearance on their work-related chat, do you know what you’re missing?

For those that have multiple teams logged in already, how about some more?

We have put together a mind-boggling list of 224 Slack channels for you to check out. These will cover many of the areas of expertise on your team and a good chunk of the interests people have too.

Dive into the collections below by clicking the links. Once you’re on the collection, follow the prompts to generate the list on your very own Deekit whiteboard and you can click through to any of the sign up pages you like… if any tickle your fancy. 😉

Marketing & Growth – 17 communities

Many of your teams will have some marketers or growth people among them. Maybe you are one of them? Startup teams can often be small and this sometimes means if you’re in a marketing role, you struggle to find others to shoot the sh*t when it comes to marketing (unless you have a marketing aficionado for a CTO like we do!).

To fill any voids, in comes Slack. Some of the marketing-focused communities really are kickass. Full to the brim with useful hints, tips and ‘growth hacks’ as well as a place to forge partnerships.



Startup & Business – 29 communities

Okay, so if the previous two didn’t push your buttons then this selection definitely should. Here we have pulled together 29 of the most cutting-edge startup and business communities on Slack. All have their own unique flavor, but all rock in some way or another.

Looking for some advice on that term sheet? This is your place to ask. Need to find a CRM solution that solves all your problems? Well, someone here will probably know that too!



Hardware & Gadgets – 27 communities

From VR to self-driving cars, there’s a lot happening right now when it comes to hardware and gadgets. This list is for the forward thinkers. The innovators. If you want to stay in the know on the newest technology out there then you should probably add one of these communities to your Slack stack.



Design-focused – 11 communities

You don’t have to be a designer to love these teams. All you have to do is have an appreciation for the creative things in life. When it comes to design there’s nothing better than actually speaking to other creatives and getting inspiration from them. In the world of startups it can be easy to spend all your day with people driven by data. So mix it up, and share some creativity bombs with those who appreciate it.



So there you have it! 224 awesome Slack communities for you to dive head first into. Although we would love for you to spend all day on Slack we know that’s not necessarily good for productivity. But why not let Deekit help?

You can sign up for an account for free or check out one of our plans for a 14 day free trial, no credit card required.

Hi guys,

Though you might be interested in something my team and I just launched. We are building a Non-Profit community for SportsTech in the nordics: Nordic Sports Tech (www.nordicsportstech.com). NST is a community of like-minded innovators, creatives and adventurers based in the Nordic region, brought together by a love for sports and technology. NST focuses on connecting Sports Tech founders, entrepreneurs and organizations in Finland, Iceland, Denmark, Norway and Sweden, and building a bridge across borders. We come together to inspire and help one another, to share ideas and solve problems.

Let me know if this is a good fit for your audience, I’d love to send you more information if needed and if it would be of interest.

There is also the Techqueria Slack group which represents one of the largest communities for Latinx in Tech.

Please add kapitan
