On the flip side, I've seen founders cling too tightly to control. Sometimes the guy that is really good at getting a version 1 out of the garage is not the same guy that is good at calling the shots once it's a 60 person company. Taking the stance that "I want to retain control," is obstinate and egotistical. The proper stance is, "I want to retain control until someone better comes along." That may be never. But it's the right attitude to have. In the end, it's not about who controls what, it's about who's more likely to make all the time and money that's gone into the company worth more.
