Mercury

Mercury CEO Immad Akhund said the business-banking fintech has reached $1 billion in annualized revenue, up around 50% year over year, and now serves more than 450,000 customers (Newcomer, Oct 19, 2026). On Oct 20, 2026 Mercury launched Mercury Payroll, which runs W-2 and 1099 payroll, files federal and state payroll taxes in all 50 states and offers health insurance, 401(k) and other benefits from the Mercury account. Payroll is free through end-2026, then $100 per month plus $50 per month for each person paid. It is the first disclosed $1B revenue run-rate for Mercury and adds a recurring payroll and HR line beyond banking.

On Sept 16, 2026, Mercury launched Mercury Books, double-entry accounting software built into its banking product for its 300,000+ customers. It uses AI to categorize and reconcile banking, card, invoicing and bill-pay activity in real time, connects to Stripe, Gusto and PayPal, and works with Mercury's Command AI agent. The product is free through the end of 2026, then $35 per month, which moves Mercury into accounting software against incumbents like QuickBooks and adds subscription revenue on top of banking.
