List of top B2B fintech firms
- Beyond sexy consumer firms, B2B fintech firms are growing big businesses.
- Tearsheet has compiled a list of the top B2B fintech firms.

B2B fintech companies may not be as sexy as those that touch the end customer, but they play a key role in the future of financial services.
With so many lists on the internet, it may be hard to believe that there isn't a great list that includes the top B2B fintech firms. So, Tearsheet filled the void. We focused primarily on firms that service the U.S. market.
For the sake of this article, we defined 'B2B fintech' along two lines. First, a B2B company sells to other businesses, not consumers. Secondly, B2B fintech firms provide a core part of the technology stack in financial services. So, an online bank that provides business banking is in, while a digital signature company that sells a lot to banks and lenders wouldn't make the cut.
It's a work in progress -- we plan to add more firms to the list.
The list is in no particular order.
