Many users of Slack express curiosity on the topic of its monetization, and the query ‘How Does Slack Make Money’ gets a large number of searches online.

The basics of how Slack makes money are covered in detail below.


Slack Business Model Overview 

Slack’s monetization relies on a “freemium” model, meaning that the software itself is free but that the platform offers access to more advanced features and functionally through subscription plans offered on an annual and monthly basis.

Here is how the article detailed the breakdown:

“Slack posted more than $400 million in revenue last year, up 82 percent from $220.5 million the year before. Only 15 percent of its customers paid for the service. Of those paying customers, 575 clients paid more than $100,000 each for their Slack subscriptions. That means less than 0.1 percent of Slack’s total customer base accounted for 40 percent of the company’s revenue, according to its offering prospectus.”

The company reported a total revenue of $234.5 million in its third fiscal quarter ended October 31, 2020. The Chief Executive Officer and Co-Founder at Slack- Stewart Butterfield- stated the following regarding the positive results:

In the same report, the Chief Financial Officer at Slack- Allen Shim- mentioned that the company “…ended the quarter with 1,080 customers spending more than $100,000 annually, up 32% year-on-year.”
