Prior to, during and after building our first Slack app, Please Share, we’ve been intrigued by the growth trajectory of Slack. We typically save a few numbers here and there for our own internal purposes, but today we thought we’d share some of these stats in a blog for others to consume. So, with no further ado, here are 10 pretty stinkin’ amazing statistics about Slack in 2021.
According to its most recent earnings report, Slack now has 156,000 paying customers – that’s “companies” not individuals who pay for its service. When you take into consideration organizations using both their free and paid options, that number grows to more than 750,000 customers around the world. I mean, wow! Way back in 2017, the company “only” had ~50,000 paying customers.
In late 2019, Slack reported that it had 12M daily active users (DAU). That means of all of the organizations using Slack, 12M people use the service every day. This total is still posted on Slack’s current website, but it’s likely this number has grown significantly in the past 18 months or so.
The Slack app directory includes more than 2,200 apps including our personal favorite, Please Share – but we’re fans of many more too. Apps fall into categories ranging from Productivity to Sales and from Developer Tools to HR & Team Culture. Each app provides a way for a company, team or department to get a little more out of Slack by streamlining workflows and processes.
For its fiscal year ending on January 31, 2021, Slack is expected to report revenue of $902.6M. In 2014, the company’s revenue was $12M – talk about skyrocketing. The company also has 106 customers that each generate more than $1M in revenue and 1,180 customers that generate more than $100K each year in revenue.
Based on a survey that yielded 2,707 responses, Slack concludes that teams that use its platform are 31% more productive. Other benefits noted include: working faster, sending fewer emails and attending fewer meetings. Still, Slack can be overwhelming at times, especially if you’re out for a few days. There are lots of articles on how to best use Slack and be productive. You can read a few here, here and here.
Slack is used by 65% of Fortune 100 companies. According to our rough calculations, that’s 65 big companies, but please correct us if our math isn’t right. The service is also used by businesses, organizations and schools in more than 150 countries.
In the past year, there have only been four disruptions to Slack’s service. Pretty impressive when you consider its global reach, scale and user base. Now watch, there will probably be a major outage tomorrow.
More than 64,000 paying customers use Slack Connect. For those not familiar with Slack Connect, it enables companies to collaborate with one another via Slack through shared channels. For example, a PR firm using Slack can communicate with any of its clients, who are also using Slack. We’ve seen the benefits of this at several of our previous employers.
In December, Salesforce announced its intention to acquire Slack for a whopping $27.7B. The deal is expected to close between May and July 2021 and Slack’s 2,280 employees will become part of the Salesforce empire.
