Onboarding some services is surprisingly easy. Like MattJ mentioned there is now prosody's mod_invites. For phone-based users, quicksy.im is doing a very good onboarding job. It's a fork of conversations (by the same maintainers) with phone-number based contact discovery like Signal and others do. Also worth mentioning, when you have privacy in mind, Jabber/XMPP is very easy to join as most operators don't have any problem with Tor users, and Tor support (also other proxies) is well supported in most clients.
