About Mercury

Mercury is the go-to business bank for startups, offering a modern banking experience designed for tech companies and their workflows. Unlike traditional banks, Mercury has no monthly fees, no minimum balances, and a beautiful interface that doesn't feel like banking software from 2005. Key features: free checking accounts, Mercury Treasury (savings with 4%+ APY through partner banks), virtual and physical debit cards, wire transfers, and international payments. The API is excellent—automate payments, pull transaction data, and build custom financial workflows. Mercury Vault provides FDIC insurance up to $5M through sweep networks. The platform integrates with QuickBooks, Xero, and tools startups actually use. Note: Mercury is not a bank itself; banking services are provided through Choice Financial Group and other partner banks. Limitations: US-only (though international founders can apply), no physical branches, and sometimes slower approval process. Best for US startups wanting modern banking without legacy bank friction, especially seed to Series B companies.
