The startup will always have a place in the ecosystem.
The exec I was talking with said Google Wave had more than 30 people on the team. He had done his own startup and knew the man-month myth. For every person you add to a team, he said, iteration speed goes down. He told me a story of how Larry Ellison actually got efficiencies from teams. If a team wasn’t productive, he’d come every couple of weeks and say “let me help you out.” What did he do? He took away another person until the team started shipping and stopped having unproductive meetings.
