I like these kind of stories. Insight into these situation is inspiring. When I hang up the gloves in my current role I'll probably do something similar.
But, come on ... isn't it just a touch disingenuous to call this a bootstrap situation?
I assume an ex-Google developer jettisoned with a decent safety net. Perhaps I'm wrong. But I have a very different idea of what bootstrapping is.
Anyway, kudos to you ... making your own move is brave and commendable.
