There might not be space left? I know of a few companies that have already been admitted, and they're filling slots fast.

I don't know how much they budget for overflow.

Don't let me discourage you. I'm just following my own suspicions. My company is at a $2M run rate and I'm thinking I shouldn't bother applying since I missed the window.

(Dang, care to comment?)

I still want OP to make the best of their time in YC and their runway. There are plenty of other great ideas out there rather than being a freight train hop-on.
