Just don't. I lost a few friendships due to bad blood between us. While we had even previously worked together on the project for years, we hadn't yet incorporated it formally. But once we did, we were already being tested. We had conflicts on most of the big picture issues of the startup, and later on, I found out that he was trying to get me to lose my equity by getting me expelled from the company (we were working in a sensitive space and anything that looked bad meant being disbarred from working in the industry). Forging certain documents, badmouthing and backstabbing me. I could prove some of it to save my skin, but not everything, so he still managed to stay on. In the end, we managed an exit, but we were just lucky now coming to think of it. On the other hand, I started up my current investment firm with a guy I had vibed well with after an interview. He is more than family to me. Granted, there are so many years of maturity between then and now.
