Slack started off as a messenger in 2013 with 16K active users in 2014. According to Business of Apps, by 2021, Slack has $902 million in revenue, $292 million in profit, and 12+ million users. Today, Slack is more than just a messenger. It is actively used by more than 750K organizations to do business, due to its convenience. For example, the slackbot feature handles routine tasks, and workspaces allow gathering teams to discuss work-related topics. Channels organize your conversations, it can be public to everyone in the company or invite-only (private). Meanwhile, the greatest Slack feature is the ability to build communities.

Unfortunately, although people who eagerly use Slack for team communication have a vague idea about Slack communities and which of them they should engage with. In this article, we’ll try to demonstrate that Slack communities are your go-to place to find clients, partners, advice, and help in your B2B business.

Slack communities. Benefits and limitations

The killer feature of Slack communities is that they are created by professionals and for professionals. In most cases, you need to get an invitation to join, so there are much fewer odd people there. It’s a tool to unite people around the world who share their knowledge and experience to help each other in professional and personal growth.

There are thousands of communities in total and the number keeps growing. The key reason for such popularity is convenience. Slack communities help companies bridge the gap between internal and external communications.

Initially, Slack was designed and used as a team messenger. Team members got used to Slack as an intra-team communication platform and, naturally, found it super convenient to create communities with fellow professionals outside their teams. The only thing they have to do is to switch workspaces on your Slack board.


  • Priceless source of information. Slack communities are different from other communities, groups, and forums in their business orientation. Here, professionals discuss their needs and pains. Often, the needs of professionals equal business needs. That’s why Slack communities are a great source of information about your market and the place to fish for leads in B2B.
  • Communication with users instantly. The instant chat feature promotes the free flow of thoughts and bouncing ideas between people, so you’re sure to get a response within a few minutes. If you want to grab the attention of every member of the channel, use the “@channel” command. This will send an alert to everyone.
  • Getting inside industry knowledge. Many Slack communities hold sessions where experts volunteer some of their time to answer any questions the channel members have. It’s a great chance to get an up-close and personal look into the lives of industry experts. You don’t even have to actively participate to learn something new. If you don’t have any specific questions, just load up the channel at the specified time to read experts’ answers.


  • With a free plan, you have access to 10,000 of the most recent messages in the community. It’s a drawback as the discussions that take place in a community are the most valuable assets. Every message that is unsearchable results in diminished value.
  • It’s a challenge to find an open community. Most of them are available when you receive an invite. On the one hand, it means there are no odd people in this community, on the other hand, you waste time waiting for a week or more to get your request reviewed. Fortunately, there are ways to find open communities, as well. In our article, we’ve given you the places to search for open communities and offered the lists in which Slack communities have been gathered based on different interests, locations, and topics.

How to use Slack communities to grow your business

In this section, we’ll give you examples of how a number of Slack communities can cover a number of needs of one business.

The golden rule in using Slack communities: If you want to cover a number of needs of your business, participate in different communities. What does it mean?

  • If you want to boost your skills or find a partner, go to a community dedicated to your line of business.
  • If you want to make a great product or provide a service, go to the community with your target audience. There, you’ll find all about their pains and needs. For example, if you develop a service or a product for marketing, the place to meet your customers and get insights is marketing communities. If your target audience is people in sales — join sales communities. And so on. There’s a community for every business demand.

Examples of how different professionals can benefit from Slack communities
