* Paddle is off the list because they don't do marketplaces (well they emailed me and said they might but it depends on the revenue split, which is sketchy to me)
* Mollie also has a "contact us" form and is likely a waste of time.
* Stripe Connect seems like the real deal, but if you're in an unsupported developing country like me (ZA) it comes with additional challenges I still haven't figured out i.e. while it's easy to establish a company in a country supported by Stripe, opening up a bank account without a flight to that country for KYC is basically impossible.
* Beware Stripe Atlas as a non-US citizen: owing a US company comes with very complicated legal obligations in all your future banking and tax dealings
Also, it's super annoying how every thread on HN about this has a majority of people who don't understand that marketplace/platform payment solutions are not the same as direct charge solutions.
