On one hand, the general impression you get when preparing for your application (via FAQs, Startup School, YC videos, etc) is very much in line with [1] - YC is looking for _very_ early stage.
But once you go through the actual application you feel focus shift towards [2] - metrics and $. That is to say (with admittedly some not-having-been-selected bias), I feel [2] is a significant factor in deciding on applications. So as I weigh in on whether to apply for the next batch, I'm not sure whether a product I've just finished building makes sense for YC and whether I should gamble on attempt #3.
I think it would help both YC and founders if they take some steps to make this clear(er) for potential applicants.
[1] > In general, there is an evident focus on the very early stage without a product. The main theory and advice are about how to figure out what to do, how to build an MVP, how to launch, how to talk to customers, where to find the first 10 customers, how to raise the first money, and so on. Needless to say, for companies with tens or even hundreds of thousands in revenue it won’t be very valuable.
[2] > [...] present dry facts—how much money customers already paid you, what the size of the market, if you count all the units you can sell, what you have actually built and what is working today. And this will always sound bad for anyone, it just can't sound good in the early days.
