> So I built something people wanted. Consumers wanted it, doctors wanted it, I wanted it. Where did I go wrong?
A lot of people in this thread are talking about the woes of ethical doctoring, the problems of healthcare, and so on. The reality here is that no one wanted it -- at least no one that he was selling to. I can relate. I've been there -- building something for months and then hearing crickets. The Y Combinator motto -- "Make something people want" -- is actually pretty tough to get right. In fact, it's the crux of any viable business. The reason why 9/10 businesses fail is largely in part due to the fact that they aren't making something people want.
Prospective customer interviews suck (especially for technical folks), but they are integral to building a product people want. Doing them before an MVP is crucial.
