We also don't hear much about the people that YC rejects which is, in my humble opinion, equally if not more indicative. Because often times founders during YC's program change their idea (I think Ark.com was an example IIRC). I was rejected by YC in Nov '12 on an idea. I actually applied as a result of the application extension granted due to Hurricane Sandy. A week after applying, I wish I applied with the idea of my current company, MakeSpace.com, which Mark Suster from Upfront Ventures funded less than a week after I received my rejection letter from YC. I wouldn't change anything because I'm very happy where we are today. But there is hope if you get rejected from YC. What other founders (same or different idea) were rejected from YC but went on to start growing startups?
