These founders haphazardly threw a new paid feature into their app just to try to impress the YC team? They should have taken the time to do market research and do it right rather than risk alienating their user base. I wonder if getting rejected was a big enough blow to their ego that they couldn’t see clearly, just like college applicants will go to top ranked colleges with no concern for the price or the risk/reward profile of that decision, but instead so that they can brag about being the best. YC is “the best”, but that doesn’t make it right for every startup.
