This is incredible! I am not sure how to read it right, you cay that he gave you company just now, and later you say that ``a year ago when we started, he sold the project to me as "willing to explore opportunities in different fields and would appreciate some help"''.

A business is a lot of fun and potentially big profit, but also a huge responsibility, make sure you do your very best running it. Be aware that not all startups have a huge payoff in the end. The worst of owning businesses is not a quick flameout, but a long and drawn own miserable existence while eking out substandard returns. I am sure that it will not happen on your case!
