How Do Tech Start Ups Typically Process Payouts?

Hi All - First post here. I've built a Start Up that I'm attempting to take live on the App Store. It's similar to Uber where I connect two users. One user will pay the other and I take a service fee for the connection. My question is, how do Start Ups typically pay the second person? Is this done via wire transfer? Are there other ways to go about this? The initial user pays by credit card, but then what? This is a hurdle that I'm having trouble finding the answer to. Any advice is sincerely welcome. Edit: For context, I use Stripe for credit payments.
