This is a bit of a tangent, but if you don't get in, don't read into it too much. The rejection could be due to many factors. It could very well be that you were rejected by the stage of your company. You may not have built out enough, or haven't had enough validation yet. I know a solo founder who didn't get in, but went on to raise 20m plus for his company (tuition.io). The fact that he was a solo founder and that he was still developing the product could have been the issue of why he was rejected. He went along to create a company that has 50+ employees. This is all to say you really have to develop the idea and see where your traction is to validate your idea. YC is a great organization to have backing you, but it's not always perfect in selecting great companies. Learn from the rejection, and apply those lessons, but commit to building a company.
