I was one of those accepted then rejected. Beforehand they announced that everyone had now been accepted, they offered to provide feedback to the rejected applicants which I received. The reasons my application was rejected was I was a single cofounder and was not working on my startup full time - yet. I can’t afford to do so as I look after my family here and overseas. So this vetting process although understandable does not always necessarily mean people who were rejected had shit ideas or that yours was more superior. This is a startup school. The point is to guide even so called startups who “don’t have their shit together” to a place where they do. As a single founder, I appreciate being part of a community that will give me ideas, feedback and guidance so I’m obviously happy about YCs decision
Best wishes
