Real Time Math

Real Time Math is a payment processing product. RTMath offers .NET and Java libraries for numerical calculations and financial modeling, including live data visualization tools. Put simply, it is about accepting cards, bank transfers and wallets online or in person.

Who is it for? Mostly any business that takes money. They also list FinTech and Real Time, so expect those to show up in the feature set. They are a very small team, 1 to 10 people, which usually shapes who they work with. Small vendors mean quick answers and real influence on the roadmap, but check who covers support when someone is out.

Real Time Math is based in Boston, Massachusetts. Their site is rtmath.net.
