Thank you. But I was more interested in YC's perspective. I've done enough research and am confident i can write a good application (I've written business plans and pitch decks and raised money with them too before) However I was curious about why YC selected those single founder startups. Of course the application has to be top quality, but I'm sure there are lots of others whose applications are top quality but still don't make it. Thanks!
