As a startup founder, I wish every startup can be part of YC. But at the same time, I hope YC does not end up investing ALL promising startups (which become big later) -- because if that is the case, it will be a disaster for any other startups that fail to get in YC, the unfundable signal is way too strong to investors.
In that sense, I appreciate companies like Buffer, Uber/Lyft etc.
Even if YC could get to a point where they fund all-and-only the successful startups, if you're not funded in one batch it doesn't mean that you can't learn, fix your issues, and get funded (and thus successful) later on.
In that sense, I appreciate companies like Buffer, Uber/Lyft etc.
