Yes. I had a colleague apply for TechStars and her takeaway from the interview was "he was really focused on where the business was." Doesn't seem in line with what I've heard about YC's primary interest (it's not the business model).

It seems kind of obvious that most successful startups don't succeed via the business model they started with. And that great founders can change business models more easily than great business models can change founders. These things are so obvious that they're cliches, in fact, but that doesn't mean that they're common practice.
