I've been working in a company for two tears, builsing it from ground up as a CTO with a CEO and COO. Two years in, with 60 people on board I was managing a project which was bringing serious profit into the company, and they decided to cut me off. Reason: they don't trust me anymore, real reason: CEO wanted more money for himself and less money control from me and the other guy.

Turned out fine as it made me start my own business.
