As someone who unsuccessfully applied for YC W21, and who also launched a product on Kickstarter in the last month, I'm going between "kind of funny" and "I'm so confused".
We didn't make it into YC, though I did get the "you were in the top 10%, please consider reapplying" email. I thought I had some idea of why we didn't make it, and what I'd change if and when we were to reapply. Hell, given that our business has grown a ton, I figured we'd have a strong application.
But seeing this makes me think that I might have some really fundamental misunderstanding of the application process.
