We've been using Wire in our company for a few years now, I can't say it's a great UX or bug-free, but it gets the job done and supports most things we want like being available on all platforms, key verification (proper e2ee, not like Keybase that trusts the server on first use), (group) calling and (group) video calling, audited, open source, sending files of course, timed/expiring messages, no need for a phone number upon registering... it's really quite complete if you're willing to put up with it being a sluggish web/electron client. Well, and the network effect: I wish more people were on it so that wouldn't be a barrier, but Keybase had the same issue there so this might be a good place for Keybase users to continue chatting.
