Steve Blank's biggest failure as a startup CEO was at Rocket Science Games. The team lost $35 million because the business model and the founding team didn't match. When he looked around at the executive staff, there wasn’t a single founder who was a gamer. Worse, there wasn’t a single person who had come from a game company. Nor was there anyone with this experience on the board. In the end, it made beautiful looking products that weren’t much fun to play.
