There are a lot of chat apps, I can't think of many with successful business models attached. Things like Skype and Hangouts are huge, userbase-wise, but dubiously valuable to the companies which bankroll them with profits elsewhere. I guess Skype has banner ads? I can't imagine Discord makes money yet, their subscription plan doesn't seem like a good value, I don't know why anyone would pay it.
There are too many chat apps already, also. Most of us want less chat apps to talk to all our friends, not more.
