At YC, we were challenged to do things that don't scale – to start with the perfect experience for one person, then work backwards and scale it to 100 people who love us. This was the best piece of advice we've ever received.

I doubt that Stripe would have worked without YC. It's that simple. Acquiring early customers, figuring out who to hire, closing deals with banks, raising money – YC's partners were closely involved and crucially helpful.
