We got a pre-interview where one of the YC partners asked some questions about the business model, so we were optimistic, but got a rejection letter today. For those of you who got an interview, congratulations! Good luck with your interview, but just in case it doesn't work out, check out this group which is thinking about setting up a Demo Day after the YC demo day for those who didn't make it: https://news.ycombinator.com/item?id=14144922
