What you need to know

  • Slack highlights engagement numbers and weekly actions in recent statements.
  • Slack states that over 5 billion weekly actions occur on the platform.
  • Slack competes with Microsoft Teams that recently hit 20 million daily active users.

Yesterday, Microsoft shared that Microsoft Teams has 20 million daily active users. Now, rival Slack points towards usage rate figures in statements to Thurrott.com.

Slack told Paul Thurrott, "As we've said before, you can't transform a workplace if people aren't actually using your product." They also added that "Slack continues to see unmatched engagement on our platform with 5+ billion weekly actions, including 1+ billion mobile actions. Among our paid customers, users spend more than 9 hours per workday connected to our service, including spending about 90 minutes per workday actively using Slack." Slack's emphasis on weekly actions and usage rate indicate that Slack's focus is people using a service heavily rather than the total number of users.

Thurrot points out that Microsoft Teams had 27 million voice or video meetings in the last month and 220 million open, edit, or download actions on files stored in Microsoft Teams last month. These figures indicate a low engagement rate, including about one monthly voice or video call per daily active user.

It's difficult to measure these services against each other without complete data to compare. At least for now, it seems that each company will focus on areas that show success and growth. The categories that Microsoft and Slack focus on likely won't line up as each company wants to focus on areas that they're leading.

  • Considering Teams is included with O365 and it's now part of new ProPlus installs by default, I'm guessing that's where a significant percentage of the 50%+ growth in less than 6 months MS is touting comes from...
  • It's active users, i.e. users that have logged in to the service. Just having Teams installed does not log you in automatically. You have to run the app and login. Try it, you'll see.
  • you just have to login once. thereafter it runs automatically on pc start. logged in doesn't mean using it
  • And after Teams installs, it prompts you to log in. Or at least it does the next time the user logs in, I forget. The point is it's very easy to log in without knowing what it is. One of my users did it simply b/c he thought it was part of the O365 activation. Funny how sensitive some MS fans get. As a lot of companies do, MS is clearly choosing their words carefully to paint as good a picture as possible. Just like Xbox sales figures. They stopped announcing console sales years ago when it became clear they were never going to get anywhere close to PS4 numbers. Instead, they focus on Xbox Live "engagement".
  • As enterprises migrate off Skype for business they will overwhelmingly choose teams. Sorry Slack
  • As enterprises are migrated off of Skype for Business, replaced by MS with Teams, you mean. There is no option. I won't argue which is better. I have no experience with Slack. If you have O365 Business though, you do, or soon will, have Teams, like it or not.
  • I know only that the free version sucks for slack. Been using it for a project with like 6 people and after one month i had everything archived...that's really bad.
    Trying teams for a few days, it looks ok and i like the integrations till now. Never heard anyone in Romania speaking about it, but...if we don't have problems at work i might suggest it.
  • What happened to Teams for life?
    We migrated from Skype for business to Teams. No complaints for now. It integrated well with Office products, share point and One drive. Slack might be popular among small companies but Teams a better choice for enterprise using O365.
