in the business world this simply isn't true. you don't assume that company will succeed because you give them money or mentorship, you assume that primarily good businesses will take money and mentorship and translate those things into growth.

that being said, I'm sure there are outlier scenarios where a company can plausibly say "we signed up for accelerator X and they sent us down the wrong path for x, y, and z reasons. we'd like to do it right this time around." and YC would take that into account.
