SampleExchange

SampleExchange is a software venture that aids the development of urgently needed novel vaccines. The job it does: accepting cards, bank transfers and wallets online or in person.

Who is it for? Mostly any business that takes money. Alongside the main category they mention Blockchain. As a small product team themselves (11 to 50 people), they tend to serve customers of a similar scale best. Small vendors mean quick answers and real influence on the roadmap, but check who covers support when someone is out.

SampleExchange is based in Menlo Park, California. Their site is sample.exchange.

Our checklist for this category: rates, payout timing, chargeback handling, and developer tools. Ask for a trial on your own data, not a canned demo.
