The first pure-play online bank, Security First Network Bank (SFNB), launched in 1995, just a year after Amazon.com. But unlike ecommerce, digital-only banking was slow to catch on. The legacy banks (Wells Fargo, Bank of America, et al) maintained market share by providing digital services deemed “good enough” to retain customers loath to switch banks.
But that began changing in the mid-2010s, first in the UK, then elsewhere as well-financed digital players started making inroads with consumers. There was Monzo, Revolut, Starling, Nubank, Chime, just to name a few. But we still haven’t seen a breakout small business bank, partly because of the love/hate relationship business owners have with big banks.
In the adjacent SMB lending space (see our Top 30 Digital Lenders list), top brands such as Kabbage (now American Express), Square, Paypal, Amazon, Brex, and others have grabbed significant share. But there is not yet a place where small businesses flock to get deposit, payment, and financing needs met in a single interface. Brex was probably the closest, but it recently abandoned the SMB market to focus on larger enterprises.
So who are the best digital challenger business banks? Let’s start with our definition.
- Centered around deposit and debit/charge card services (eliminates Kabbage and most SMB lenders)
- Predominantly focused on small-business financial services (eliminates Paypal, Amazon, Block
- Primarily digitally delivered (rules out Wells Fargo, BofA, and the majority of traditional banks*)
- Founded since 1999

*Our business model depends on revenue from referrals and sponsors. When you see a referral link in the URL, we may earn a fee for new accounts (thanks!). This can improve visibility on our website, but does not impact the company’s FAB score.
** The FAB score, Fintech Attention Barometer, is a proxy for the overall size of a private company since they typically do not release traditional metrics (# customers, deposits, AUM, etc). The score is based on VC funding, website traffic, mobile downloads, and the number of employees. It’s a work in progress, so expect changes in the formula.
***Funding is the amount invested into the company as either equity or debt.
****Provide SMB checking accounts, but is not its core business.
