From debit wedge to financial OS
Ex-Chime employee on Chime's multi-product future
The key strategic move was that neobanks inserted themselves at the customer touchpoint while banks and processors stayed in the background. Chime did the expensive work of getting direct deposit, app engagement, and card usage, then shared the merchant fee stream with its sponsor bank, network, and infrastructure partners. That let fintechs look like the bank to the user without owning the full banking stack on day one.

In practice, being higher in the chain meant owning the app, brand, onboarding, and paycheck relationship. The sponsor bank held the license and accounts, Galileo or similar providers ran card plumbing, and Visa or Mastercard moved the transaction. The fintech captured the biggest economic share because it owned distribution.

This worked especially well after the Durbin rules capped debit interchange for banks above $10B in assets. Fintechs partnered with smaller exempt banks, issued debit cards, and split roughly 1% to 1.5% of card spend economics while avoiding the cost and timeline of getting a bank charter themselves.

The limit of that model is that interchange is thin and tied to card swipe volume. That is why Chime and peers moved into lending, subscriptions, and other products. The front end customer relationship was the wedge, but the long term prize was using that relationship to sell higher revenue products than debit alone can support.
Going forward, the winners are the fintechs that turn that front end position into a broader financial operating system. The debit card and direct deposit relationship gets them in the door, but the real value comes from layering on credit, savings, bill pay, investing, and payroll linked products before banks and software platforms capture that same customer entry point.
