Just a gut feeling. There's no real cost to applying, so why <i>wouldn't</i> a single founder apply?<p>Given the number of people that post about looking for a cofounder here, I'm just guessing that a lot of people don't have one, but feel that they've got a good enough idea to make a business. Some of them really will have what it takes; but I'm sure the proportion of single founders that apply is quite different that the proportion of single founders that are accepted.
