Yes of course, I just think it's unhealthy to focus on selling a company early, when the ideal result would be to be a grow to a point where you have a choice of selling or expanding. I'm sure in your case this wouldn't apply, but focus on an exit at all costs can distort perspectives and encourages companies like color which spend a lot of money without bothering to produce anything people want.

In practice, either can work. We consciously built Viaweb to sell.

Could you describe in detail some of the "We can do either X or Y, but because we are building this to sell, we will do Y" situations, for specific values of X and Y?

The first that comes to mind is raising a series A. You should not do that if you want to sell early.
