Best Site for Business Banking
Summary
The best business banking site depends on your business stage and what hit by the 2024 Synapse failure means to you. Mercury is the polished startup-focused choice; the Synapse Financial failure in 2024 affected fintech-backed accounts industry-wide and Mercury customers should understand the partner-bank model. Relay Financial is the underrated multi-sub-account winner. Novo targets sole proprietors and small LLCs. Bluevine offers competitive interest rates. Traditional small business banks (Chase, BoA) provide stability with the worst UX. Most listicles default to Mercury without flagging the partner-bank model concerns that the Synapse failure made concrete.

Frequently asked questions
What happened with Synapse in 2024?
Synapse Financial Technologies, a banking-as-a-service infrastructure provider, failed in 2024, affecting fintechs that depended on it. Customers of some fintechs (notably Yotta and Juno) lost access to funds for extended periods. Mercury was not directly affected because it does not use Synapse, but the broader episode made the partner-bank model risk concrete. Always verify your business banking provider's partner bank and FDIC structure.
Is fintech business banking safe?
Generally yes when partner banks are FDIC-insured and the fintech is operationally sound. The Synapse episode demonstrated that even FDIC-insured deposits can be inaccessible during a fintech failure. Diversify across providers if your business operating cash exceeds modest amounts.
Why is Mercury rated above Chase?
UX, fee structure, and ecosystem fit for startups. Chase wins on stability and breadth; Mercury wins on day-to-day usability. Many startups use both — Mercury for daily operations, Chase or similar for borrowing relationships.
Do I need a business bank account?
Legally required if you have an LLC or corporation. Strongly recommended even for sole proprietors to separate business and personal finances for tax clarity. Many of the options above are free for basic use.
What about international business banking?
Wise Business is the strongest fintech option for international transfers and multi-currency holding. See our international bank transfer ranking. Combine Wise with a US-based business account if you do significant international receivables.
