Does anyone have advice for people working on challenging tasks (which you couldn't get an MVP done with a $500k seed)?
Specifically: I've used my first company to fund progress on a hard problem. So it's pre launch but significant Dev resources put in, I don't think there's any obvious fundraising path for this situation
YC does fund "hard products". They call it "moonshot projects". They have funded companies that are building supersonic planes to companies building complex biotech products.
