I agree. Once you get past the idea phase of an early startup, everyone is essentially a builder. Even salespeople, business developers, and negotiators are contributing towards "building" the company. Once a company moves beyond the startup phase, the role of the founder begins to change -- the founder then needs to find a place in the company or move on to the next challenge.
I have been writing a book based on my own entrepreneurial experience. I am half way done. My last chapter is entitled "The Nail that Keeps the Air from Leaking" and that pretty much describes my own experience as an entrepreneur building a company from scratch.
Once the company is profitable. It is really boring. Then the challenge is to find a way to leave (without others feeling that you have abandoned them). And there are so many ways to do it wrong but the main one is that we tend to overstay our welcome which is human nature, so the founding entrepreneur becomes both a bug and a feature.
