As someone who has joined a couple of accelerators and evaluated a few others, I would say no.

I've had a lot of great mentors who came from the wrong backgrounds and weren't able to advise me on it. Also joined many of these "guaranteed" programs that just didn't fit my approach - some felt too exploitative, some just didn't fit my personality and would make money but at a personal cost.

So just follow your gut.

Also as YC has advised, in the earliest stages, you need to be listening to customers and building what they want. Everything else - marketing, mentors, comes later. Otherwise it'll likely bite you back in the future.
