In the unlikely event you didn't already know this, YC's investment is not meant to be the only funding a company ever raises. It's just meant to get the company to the point where it can raise more from the next round of investors. Which in the case of a company building the sort of thing you can't launch version 1 of in 3 months usually means building some initial proof of concept.
Very good point, pg. But compared to software startups, hardware is really a field that requires much more inputs than just a concept/idea to initiate in terms of time, money and man power, especially semiconductor chips. I think that's why there has been no such investment in YC for such a short term of 3 months. Am I right?
