If you're interested in famous co-founder issues, I maintain a list here: http://thestartupconference.com/2016/05/13/famous-co-founder-issues http://thestartupconference.com/2016/05/13/famous-co-founder.... Snap, uBeam, Cruise. Let me know if you know of more to add to the list. I could probably write a book about co-founder issues (I gave presentations on that topic in the past, that's something :-). The best co-founder is someone you worked with before. You know them. Starting something with a co-founder you don't know? It goes downhill very fast. There is a very fine balance that is hard to achieve. You want to have complementary skills, but still be on the same page. You need to trust the other co-founder and not micro-manage, and get the same trust in return. If you have no shared history, it's extremely hard.
