Although that seems a bit reckless: only having 3 months runway; good job executing and sticking to it. I'm impressed you didn't just find another job once you had your injury.

I wanted to also mention, only a fraction (I don't know the exact fraction) of YC teams invited for interviews get funded. I hope you keep your work ethic up, I'm sure regardless of funding you'll be successful, if not this venture then the next.
