Salsa

Salsa offers a payroll infrastructure platform that allows businesses to lauch embedded payroll products quickly and efficiently. The job it does: accepting cards, bank transfers and wallets online or in person.

The natural audience is any business that takes money. Related areas on their profile: Developer APIs, Embedded Software and FinTech. As a small product team themselves (11 to 50 people), they tend to serve customers of a similar scale best. You will probably talk to the people who build it, which is great until you need 24/7 support.

Salsa is based in San Francisco, California. Their site is salsa.dev.

Things worth asking about: rates, payout timing, chargeback handling, and developer tools. A short pilot with your real data tells you more than any demo.
