Yeah...got our rejection.
Probably the nicest rejection letter I've ever seen, YC is definitely astute at winning hearts and minds.
We are getting involved in another incubator however it would have been great validation to get into YC. The caveat one has to hold onto is that it's your customers and users you have to be validated by, and not YC.
Great process, just building the application helped to develop insights into many of our assumptions, and product market fit. I'd encourage everyone to apply just for that reason.
