The two most interesting companies in crypto for me right now are KeyBase, and Wire.
I kind of wish there was some way for them to interact with each other, because it feels like they each have a piece of some bigger puzzle.

Although I agree Wire looks like a much more (visually) polished chat service, it seems like they (Wire) collect more data than is necessary.

So you can run your own copy of it, and be in complete control of any information it collects.
