Looking for a fintech mentor to help me build a startup

I'm looking for someone experienced in the fintech industry who can mentor me.

I'm particularly interested in anyone who has worked or works for Visa / Mastercard, Stripe, Adyen, PayPal, Square, FIS, Authorize, Paddle, Plaid, or any relevant company. I'm also looking for someone who has knowledge of how startups can negotiate with banks to get into their networks.

About me: I'm based in the US, studied computer science in university and I'm about to graduate. I am looking for mentorship in order to understand the industry better and what path to take in my career. This past year I've become fixated on the payment processing industry. I read some books on payments processing so I can understand how the system works.

I'm interested in building a technology startup in this space to take on emerging markets.
