Atlassian has called time on its chatops ambitions and dropped its HipChat and Stride chat projects into the lap of Slack.

The Aussie firm will make an “equity investment” in Slack, which will acquire the IP for Stride and Hipchat Cloud, and the Hipchat Server and Hipchat Data Center products, all of which will be discontinued.

Atlassian said it would work with Slack “to provide a migration path for customers of all four products” to Slack’s platform.

For its part, Slack described the equity investment as “small but symbolically important.” It said it would build on support for Atlassian’s Jira, Trello, and Bitbucket, and add new integrations for Confluence and other Atlassian products.

Atlassian bought HipChat way back in 2012, when the proto chat app was just two years old, and Slack wasn’t even a gleam in its creators’ eye. Last year, it decided HipChat wasn’t quite hip enough, and kicked off the Stride project which promised voice and video meetings out of the box. It also included a “focus” mode, with Atlassian at the time describing Slack as a productivity sink.

But it turns out that Atlassian and Slack were great pals all along, with the two finding time to send each cookies and cakes.

Joff Redfern, Atlassian’s vp of product management, said in a blog post accompanying yesterday’s announcement that “Stride was a bold project, and we’re very proud of the product we created and the team that created it.”

But, he continued, “One product has continued to stand out from the others: Slack. While we’ve made great early progress with Stride, we believe the best way forward for our customers and for Atlassian is to enter into a strategic partnership with Slack and no longer offer our own real-time communications products.

He added the first fruits of the promised deeper integration between Slack and Atlassian’s product lineup would be highlighted at its user conference in Barcelona next month.
