Rateseeker

Rateseeker specializes in providing a platform to compare mortgage and savings rates. The job it does: accepting cards, bank transfers and wallets online or in person.

The natural audience is any business that takes money. Alongside the main category they mention FinTech. As a very small product 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.

Rateseeker is based in Chicago, Illinois. Their site is rateseeker.com.

Things worth asking about: rates, payout timing, chargeback handling, and developer tools. Get the renewal terms in writing before the first invoice.

The facts above come from public company records. The score will come from people like you. Used Rateseeker? Rate it.
