If you paraphrase most arguments here, we would end up with a conclusion that a YC-startup is no different from a random startup. There is huge struggle getting product/market fit, things are constantly in motion, rejection by VC's etc. Somehow that doesn't seem right. I'm sure the YC founders would negotiate pretty good terms for themselves (compared to a random startup) just because they are a YC startup. For people who feel the OP is naive etc., what exactly should he have expected (net delta) because it is a YC startup?
