I apologize, I don't intend for this to sound as rude as its going to or if I'm just out of the loop but...

I don't know who you are or why I should care what you are developing? People have known that messaging has been fucked for a very long time, and many people have tried to make a one size fits all solution for messaging.

What makes you different?

In a related tangent, Messaging is really fucked. Email is thrashed. To the point that it requires consistent effort and continuous maintenance for it to be useful at all.

I love the idea of a unified service. But I don't know why facebook or skype or slack would ever give up a customer to your interface?
