Brex Becomes Fifth Third's Default Card

This partnership turns Brex from a direct sales product into bank distributed infrastructure. Instead of winning one finance team at a time, Brex becomes the built in card and spend stack inside Fifth Third’s commercial bank, which instantly gives it access to $5.6B of annual commercial card volume and a much larger pool of mid market and enterprise customers already buying financial products from a trusted bank.1 2 3 4

• In practice, Fifth Third clients get more than a card. They get Brex software to issue cards, set spend controls, automate expense reports, and make real time payments, which means Fifth Third is outsourcing the application layer while keeping the banking relationship.1 2
• This fits Brex Embedded’s playbook. Brex had already used partners like Navan, Coupa, and Sabre to drop Brex cards directly into travel and procurement workflows, then expand from that narrow use case into broader spend management and bill pay.3 4
• The strategic step up here is distribution. Brex said the Fifth Third deal gives it access to roughly 8% of the U.S. commercial banking sector through one partner, which is the bank channel version of what Navan and Coupa did in software, but with a much larger installed base.2 4

Going forward, more of the category will be won through embedded distribution inside banks, ERPs, travel systems, and procurement tools, not just head to head card sales. That favors players like Brex that own underwriting, risk, and card infrastructure closely enough to let partners offer a modern card product as their default.1 2 3 4
