Mercury Broadens Into Ecommerce SMBs

This mix shift shows Mercury is turning from a startup bank into a broader SMB money movement product. Ecommerce merchants, consultants, and bootstrapped companies use bank accounts differently from VC funded startups. They send more supplier payments, collect customer cash faster, and often care more about cards, FX, and working capital than treasury on idle cash. That gives Mercury more ways to monetize each customer beyond startup deposits alone.1 2 3 4

• Mercury had already started this expansion by 2023, when ecommerce had become its second biggest segment and consultants its third, showing the 2025 customer mix is an acceleration of an existing pattern, not a one time spike.2
• The revenue logic fits the segment mix. Mercury makes money from deposit revenue share, card interchange, international wires and FX, and debt products. Ecommerce customers are especially useful because they move money frequently and are more likely to generate payment and card revenue, not just hold cash balances.2 3
• This also pushes Mercury into a tougher market. Startup banking is now only one lane inside a wider race for SMB finance, where players like Flex and Slash target ecommerce and other cash flow sensitive businesses with cards, payments, and credit built around daily operating needs.1 3 4

The next step is deeper verticalization. As Mercury brings in more non startup customers, growth will come from packaging bank accounts with spend controls, bill pay, FX, and credit in workflows that match how ecommerce and other SMBs actually run day to day. That broadens the market and makes revenue less tied to venture cycles and interest rates.1 3 4
