It's worth adding that although the OP's company went through YC S14, the company was shut down in August: <a href="https://medium.com/@tmzier/zen99-is-closing-its-doors-8-25-169830ec7da8" rel="nofollow">https://medium.com/@tmzier/zen99-is-closing-its-doors-8-25-1...</a><p>While that doesn't invalidate the advice, it does give perspective that Y Combinator is not a guaranteed ticket to success. Startups are hard.
I say focus on customers instead of Angel Capital, get market and focus on that money instead of a Capitalist injecting money. It's not sustainable forever unless you make money for real!
