What you need to know

  • Slack is working on Microsoft Teams integrations for calling.
  • Slack CEO Stewart Butterfield confirmed the features are in the works in a recent interview.
  • The features could give Slack users a way to access cross-app calling with Teams users.

Slack and Microsoft Teams may be competitors in the work collaboration space, but they could be about to get a lot closer. Slack CEO Stewart Butterfield said that the company is working on integrating Teams calling features in a call with RBC analyst Alex Zukin, CNBC reports.

"We're working on Teams integrations for calling features," Butterfield said. Presumably, the features Butterfield alludes to would allow Slack and Teams users to call one another across apps. It's a sign that, even as the companies compete for the business from companies around the world, Slack is open to facilitating communication regardless of platform.

As more people have begun working from home in recent weeks, Butterfield reported that Slack broke a record this week with 12.5 million concurrent users. Microsoft Teams has also seen a surge to 44 million daily users as more companies accelerate the move to digital communications.

There's no indication of when the integrations might roll out to Slack users.
