You are always replaceable..even if you think you aren't. I know so many founders that gave up majority control and were kicked out of their own company and replaced by a VC-picked person.
A friend of mine hired the guy that ended up booting him out of the company 6 months later. The guy he hired removed all of his powers and then claimed that he couldn't manage the project any longer (after all of his powers were taken away of course).
To get his severance, he had to sign a piece of paper filled with complete lies about his performance.
People in business aren't nice and you need to do everything in your power to protect yourself.
