Mercury Competes With Ramp and Brex

Mercury is moving from being the place startups park cash to being the place finance work happens. Once bill pay, expenses, and invoice workflows live inside the same product as the bank account, Mercury can win more of the daily actions that made Ramp and Brex sticky. That matters because workflow software is used every week, while a bank account is often just checked and trusted to work.

• The product overlap is now concrete. Mercury already sells software for bill pay, expense management, and invoice processing, while Ramp is built around cards, bill pay, accounting automation, procurement, travel, and treasury, and Brex bundles cards, expenses, and business accounts.

• The revenue models are also converging from opposite directions. Mercury still leans on interest sharing from startup deposits, while Ramp and Brex were built primarily on card interchange and then added software. Expanding workflow tools gives Mercury a second way to monetize the same customer beyond deposits.

• Ramp remains the broadest finance automation benchmark. It reached an estimated $1B annualized revenue in August 2025, ahead of Mercury at $650M in September 2025 and Brex at $700M in August 2025, reflecting how powerful multiproduct attach can be once a finance team runs spend, payables, and treasury in one system.

The next step is a fuller back office bundle. Mercury is well positioned to keep adding treasury, procurement, and related finance controls around its core banking base, which would push it closer to Ramp's all in one finance console and make startup banking increasingly a software distribution wedge rather than the end product.
