There are exceptions, of course, but most great companies start with a great idea, not a pivot.

I think the most important thing is managing to convince dozens of sweat-shop, conveyor belt startups per year to give you equity for almost nothing, thereby guaranteeing at least some equity will eventually be worth billions merely by chance. Good job, YC.
