> Pumping money into worthless products with no return

This part shows your fundamental misunderstanding of what startups are all about.

9 failures for 1 success is expected. That means 9 worthless products, for 1 hit. But you don't know they're worthless until they've developed enough to be tested by the market. And that sometimes takes money. And that is what YC is about.

The truth is you're applying to YC just to be in YC, part of the club. You need to have a great idea and show you can execute and make a return for investors who believed in you and took your bet. Do that and the door is wide open, just like it has been the last 8 times you applied.

There is no shame in getting up and trying again, so good luck to you in the next round.
