Mercury is a financial technology platform that provides banking services for startups, founded in 2017 by Immad Akhund, Max Tagher, and Jason Zhang. It's the default business banking choice for YC-era US tech startups, offering checking and savings accounts, free domestic wires, virtual cards, multi-user access with permissions, an API for banking automation, and FDIC insurance up to $5M through a partner-bank sweep network. Mercury is not itself a bank — funds are held at partner banks (Choice Financial, Column, Patriot Bank). The base account is free with no minimums; Mercury Plus is $35/month, Pro is $350/month for higher-touch businesses. Best for US-based startups and indie SaaS founders (founders from 100+ countries can open accounts if they have a US business entity). Direct competitors: Brex (corporate cards + cash management, more enterprise-focused), Ramp (spend management + cards), Relay (similar indie-friendly banking), traditional banks like Chase / SVB / First Republic. Mercury wins on UX and ease of signup; Brex/Ramp win on corporate-card features.
⏱ 30-second verdict
- Free checking with no fees, no minimums, instant signup
- Multi-user access with real permissions, no shared logins

The Treasury product safely yields 4-5% on idle cash without you doing anything. Free money for a startup.
Key Features
Integrations
✓ Best for
Early-stage startups and small business founders who need a modern, no-fee bank account with integrated treasury and spend management. Particularly valuable for teams raising capital and needing FDIC protection with higher insurance limits.
✗ Not ideal for
Established businesses requiring specialized lending products or those needing in-person banking support. Not ideal if you need a physical bank branch or prefer traditional banking relationships.
How indie founders use Mercury
Startup checking account
Open a US business account in 10 minutes. Free wires, no minimums, FDIC up to $5M. The default banking choice for YC-era startups.
Vendor virtual cards
Create a unique virtual card for each SaaS subscription. Pause or close any card without affecting others. Sane subscription management.
Banking automation
Use the Mercury API to programmatically check balances, move money between accounts, or trigger bill payments. Treat your bank like infrastructure.
Multi-founder access
Each cofounder gets their own login with permissions. Finally retire the shared 'finance@' email and password situation.
If you have a US business entity and you haven't moved your banking to Mercury, do it this weekend. I'm serious. The difference between Mercury and a regular bank (Chase, BofA, whatever) is so embarrassingly large that you'll wonder how you ever banked anywhere else. Mercury is the bank account designed for startups. Open an account in 10 minutes online. No branch visits. Free checking and savings, no minimums, no monthly fees. Free domestic wires sent same-day. Multi-user access where each cofounder has their own login with proper permissions (no shared 'finance@' password situation). Virtual debit cards for every SaaS vendor so you can pause cards without affecting others. FDIC insurance up to $5M via partner-bank sweep network. An actual API if you want to programmatically check balances or move money. QuickBooks and Xero integrations that actually work. For anyone reading the news about Synapse: Mercury moved away from Synapse before the collapse and now uses direct partner-bank relationships (Choice Financial, Column, Patriot Bank). Customer deposits were never at risk. The transparency since then has actually been excellent. The upgrade path makes sense too. The free Mercury tier covers most early-stage startups. Mercury Plus at $35/month adds bill pay, custom invoicing, and approval workflows once you have a finance person. Pro at $350/month is for more mature businesses that want a dedicated relationship manager. You don't need to upgrade until you genuinely outgrow free. Where Mercury isn't the answer: you can't deposit cash (rare for indie founders but worth knowing). International wires work but Wise is cheaper if you're sending a lot of them. Lending is limited; for real working capital you're still going to Brex or a real bank. And you need a US business entity to open an account, which means non-US founders need to incorporate in the US first. For most modern startups, Mercury for the bank account plus Ramp or Brex for corporate cards is the standard stack. It's the standard for a reason. Recommended without reservation.

Frequently asked questions
Is Mercury a real bank?
Mercury is a financial technology company, not a bank itself. Your deposits are held at partner banks (Choice Financial, Column, Patriot) that are FDIC-insured. Funds are FDIC-insured up to $5M via Mercury's sweep network.
Is Mercury free?
The base Mercury checking and savings account is free with no minimums or monthly fees. Mercury Plus at $35/mo adds bill pay and invoicing; Pro at $350/mo adds a dedicated relationship manager. Most early-stage startups stay on the free plan.
Mercury vs Brex vs Ramp, which should I pick?
Mercury for the bank account itself (checking, savings, wires, accounts). Brex for a startup-friendly corporate card with rewards. Ramp for spend management and reimbursements. Many startups use Mercury for banking plus Ramp or Brex for cards. They complement rather than compete directly.
Can I open a Mercury account from outside the US?
You can open Mercury if you have a US business entity (LLC or C-Corp), even if you're a non-US founder personally. Mercury supports founders from 100+ countries, but the business itself must be US-registered.
Is my money safe at Mercury after the Synapse collapse?
Mercury moved away from Synapse before its collapse and now uses direct partner-bank relationships. Deposits sit at FDIC-insured banks and are insured up to $5M via the sweep program. The Synapse situation didn't impact Mercury customer deposits.
