Money and cash flow are the lifeblood of a small business. It’s an area often overlooked by traditional online banking services, so numerous specialists have launched during the past decade-plus to better serve SMB needs. Most providers operate on a dual revenue model which includes:
a.) monthly subscription fees to create predictable recurring revenue
b.) transaction fees to cover interchange and other variable processing costs.

We divided the payment providers into four categories:

  1. Charge card and expense management (see list here)
  2. Bill payments and/or invoicing specialists (see below)
  3. Payment processors (see list here)
  4. Subscription management platforms (see list here)

Note: The FAB Score (Fintech Attention Barometer) is a proxy for the size of a private fintech company.

* We have excluded PayPal from this list because they are more of an enterprise solution, and less importantly were founded in 1998, so a little old/established for a “challenger” list.
**As nerds do, we are developing a proprietary score measuring the adoption of digital financial services at private companies that do not release traditional metrics (# customers, deposits, AUM, etc). We call it the FAB score, standing for Fintech Attention Barometer. The score uses money raised, valuation and website traffic as a proxy for company size and velocity of growth. It’s a work in progress, so expect changes down the road.
**Funding is the amount invested into the company as either equity or debt.
