C4 Payments

C4 Payments offers financial services solutions, focusing on payment processing and business growth tools. In practice that means building software for you when nothing off the shelf fits.

The natural audience is companies with a specific process to automate. They also list Financial Services and Payments, so expect those to show up in the feature set. As a very small company team themselves (1 to 10 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.

C4 Payments is based in Dallas, Texas. More on c4payments.com.

Things worth asking about: portfolio relevance, who owns the code, and how they handle changes. Get the renewal terms in writing before the first invoice.
