It looks very similar to Zulip.

Can anybody contrast both ? Zulip would bring the best of slack and p2 right?

We recently adopted Mattermost at Canonical to replace IRC. While it's a great IRC replacement I am very much missing the ability to thread into sub-topics like Zulip. And creating whole new channels is hard for other team members to discover.
