Compare Mercury alternatives for startup business banking, treasury sweeps, cards, and international wires — Brex, Ramp, Rho, and Meow.
Mercury is the default startup checking account for many US venture-backed companies — fast onboarding, treasury sweeps, and API access.
Rho is the most direct alternative — banking, AP, and cards in one platform, with real treasury features.
Brex and Ramp lead on corporate cards, expense management, and bill pay. Both offer banking layers but originated in cards.
