Slack’s daily active user (DAU) count has crossed 12 million – short of the 13 million most recently disclosed by its leading rival Microsoft Teams. However, Slack says that numbers don’t tell the full story, and offers figures to suggest that users actually like using its app.
Slack, now valued at about $13 billion on the public market, announced this milestone on Thursday, ahead of its Spec user conference later this month in San Francisco. That 12 million DAU is up 37% from this time last year, Slack says.
Slack says that users spend over nine hours a day connected to the service, and 90 minutes a day actively using the app. It’s Slack’s position that figures like those matter more than any plain user number.
“DAUs (daily active users) get cited a lot, but what, really, is their significance?” Brian Elliott, vice president and general manager of platform at Slack, wrote in a blog post. “In our book, the ‘U’ is what matters: Use! Engagement is what makes Slack work — you can’t transform a workplace if people aren’t actually using the product.”
In addition, Slack reports that every week, there are five billion “actions” on Slack, which accounts for sending messages, uploading files, searching, and other ways users interact with the app.
Office 365 customers are also Slack customers
Of note, much of Microsoft Teams’ growth has been attributed to the fact that it’s included as part of the Office 365 productivity suite for businesses. However, Slack now says that of its top 50 customers, at least 70% of them are Office 365 subscribers — implying that while they may get Teams included in their Office 365 subscription, they’re still willing to shell out extra for Slack.
Slack also said that that large companies like Kaiser Permanente, Vanguard, and TD Ameritrade choose Slack because it supports an unlimited number of users and channels, whereas Microsoft Teams has a limit of 5,000 users and 200 channels per workspace.
“The way we work is fundamentally changing,” Elliott wrote. “It’s becoming faster, more adaptable, and more collaborative. This change is fueled by engagement.”
