Similar story. Multiple failed YC interviews. I did raise significant angel money from outside of SV but I still failed with that company.
Firms like YC are designed with the nearly singular goal of attracting the next Google. The primary criteria for investment is essentially "how much like [Larry Page|Bill Gates|Mark Zuckerberg] are these founders?"
Unless you're a [Stanford|MIT|Harvard] Ph.D. student you're already off to a really bad start. If you didn't grow up in an upper middle class household you're probably going to stick out in various ways you're unaware of. http://www.ycombinator.com/partners/
Airbnb is the biggest YC success. They don't fit the mold and were one rather mundane story away from being rejected.
So ignore investors. Build a great product that users want and make it grow rapidly. Then you can pick and choose which money manager you want to accept financing from.
What I've done is scaled back my living expenses and built up enough revenue that I'm ramen profitable. It sure would have been easier if someone wrote me a check but at least now I'm completely unstoppable. It took me 1.5 years of solid effort to get into this position after my previous failure which I spent 2 years on. I'm about to release the first version of the best thing I've ever done.
If you're like me all you care about is writing code and creating great things anyway. Investors can often get in the way of that. The very best products all came out of genuine interest.
Let users alone be your judge.
