We received our second rejection for an interview yesterday, but luckily for us YC was just a nice to have and not end all.
As I read through the comments, I believe many businesses forget the fact that business is ran by the numbers. Yes, can YC help you get attractive numbers for investors, but you can do the exact same thing on your own if you build something people need (love). I find it hard to believe that any investor that YC can introduce you to will turn down your meeting if you have built a business that has attractive numbers. That's what they look for anyway...YC funded or not.
For those that got an interview, congrats. For those that didn't, keep going and be great in what you are doing.
