Hey Sam,
I'm working on this idea on my free time but for now it's in an early stage. We believe strongly in it but we don't have yet a ready prototype which means we don't have any structure, users, revenue, etc..
I'm wondering if YCombinator's goal is to encourage people from initial concept or help existent startups to grow and go further ? Knowing our story, do you honestly think we have a chance at this time to be selected by YCombinator ?
Thanks.
