But generally, he's looking for people who are smart, very determined, and like to make things.
Would PG approve posting a few UNsuccessful applications of different level -- from amusing, to boring, to pretty close? -- guess people like to see those just as much, I sure do, and am not merely joking here.
You basically have to prove that you are a great hacker and have a demo, ready to go.
The things that would come to mind (though mind you, I'm only an applicant at this point as well):
* Stand out * Show you know what you're doing * Focus on what's important * Be confident in your idea and your people
I do know very much that the tone has changed a bit in the interview (or did last time). They will ask a good bit about monetization. So your application will get extra points if you can show very clearly how you eventually plan to turn this into a concrete business.
- You <em>understand</em> what you're building, who needs it and why
- You care about this project (incl. that you have already started working on it)
- You are the kind of team who can pull this off (realistic, committed, hackerish)
That's what YC is looking for; so the application just needs to be representative of that.
