Good point. What does "proven" mean? Even if you've worked with someone before, and things worked out well, there's no guaranteeing it will be 100% the same the next go around. Miscommunication is probably the biggest problem here. Were both of you expecting to work 80 hours a week on the startup for the next 3 years of your life? Or was one person really thinkg "I'll see how this thing plays out... might have to bail after a few months if it doesn't."
