YC had every reason not to invest in us - we weren't technical, we already had angel money which complicated issuing new shares and we were based in the UK. they still funded us.
YC funding is less about worrying about all the reasons you won't get funded and concentrate on making as many reasons why they will fund you.
Nonetheless, I'm happy to hear that you were able to find good cofounders!
This was replicated in at least one other yc startup I know.
