Unfortunately, I think that some companies are in it for the funding as opposed to the experience itself. The real value of YC has little to do with any checks you get, but the knowledge you earn. I would take a YC spot over a $5 million VC check in an instant. $5 million buys a lot of Heroku dynos, but the YC-knowledge/experience is something that can make you potentially 50x anything you could get without YC.
