Online Business Banking For Startups, Small Businesses & Scaling Companies

Mercury is a modern online banking platform built specifically for startups, small businesses, and high-growth companies, replacing traditional commercial banking with a fully digital experience. It offers checking and savings accounts, multi-currency accounts, virtual and physical cards, and API integration. Account opening is entirely online with no minimum deposit, no monthly fees, and no charges for wire or ACH transfers, making it cost-free to start. The platform's key differentiator is its deep integration capability for tech companies. An open API allows custom approval workflows, automatic transaction syncing with accounting software like QuickBooks or Xero, and even code-initiated transfers. A visual dashboard shows real-time cash flow and financial health, while multi-currency accounts in USD, EUR, and GBP support low-cost cross-border payments, saving time and fees. Mercury serves companies at every stage. Early startups use the free account for quick launches, focusing on product development. Growing teams benefit from multi-user permissions, expense approvals, and category tracking. Scaling tech companies leverage API automation for thousands of transactions with minimal manual error. It works well for SaaS startups, e-commerce sellers, and remote teams. Since 2019, Mercury has gained hundreds of thousands of business users and processed billions in transactions, becoming a top bank alternative in Silicon Valley. It partners with Y Combinator and a16z, uses bank-grade encryption and SOC 2 certification, and provides FDIC insurance through partner banks. Developer-friendly documentation and an active community reinforce its appeal to technical founders.
