Double

Double is a web app that provides optimised donation checkout tools and fundraising widgets for nonprofits. The job it does: accepting cards, bank transfers and wallets online or in person.

It makes the most sense for any business that takes money. They also list FinTech, so expect those to show up in the feature set. As a very small product team themselves (1 to 10 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.

Double is based in New York, New York. More on double.giving.
