Best Bank Accounts for Startups
Banking built for funded companies: free wires, real yield, and software that scales.
Startup banking is its own category. You need free wires for investor money, FDIC coverage far past $250k for the round you just closed, treasury yield on idle runway, and software your finance hire will not quit over. Several of these accounts exclude sole proprietors entirely, which tells you who they are built for.
#1 · Best overall
Mercury Business Banking
None on checking/savings; Mercury Treasury yields roughly 3.0-3.6% net ($250k minimum)
$0 (banking is free on every tier)
None
The gold standard for startup banking: free ACH, free domestic wires, and free USD international wires on every tier, $5 million in FDIC sweep coverage, and best-in-class product polish with full API access. Mercury Treasury puts idle cash to work at roughly 3.0 to 3.6% net once you cross $250k. The free tier alone outclasses most paid competitors.
#2 · Best for treasury yield
Brex Business Account
Treasury money market yields ~4.01% (up to 4.36% at $20M+); checking and Vault pay nothing
$0 (Essentials)
None (US-incorporated companies with an EIN only)
Brex pays the highest no-minimum yield in the category, with Treasury starting around 4.01% and tiering up to 4.36% at $20 million plus, alongside a Vault that sweeps across roughly 24 banks for up to $6 million of FDIC coverage. The checking-Treasury-Vault structure lets you dial risk against liquidity deliberately. Corporate cards, travel, and expense tooling come free on Essentials.
#3 · Best FDIC-insured yield
Ramp Business Account (Ramp Treasury)
Roughly 2.0-2.5% variable on checking (true FDIC interest); Investment Account yields ~4.38% (money market fund, $5k minimum)
$0 (included with Ramp's free tier)
None for checking; $5,000 minimum for the Investment Account
Ramp's checking pays roughly 2.0 to 2.5% as genuine FDIC-insured bank interest, not money market fund yield, with coverage extended into the millions via IntraFi sweep. Domestic and international wires are free, and the whole thing comes bundled with Ramp's already-free card and spend platform. If you are on Ramp for cards, turning this on is free money.
#4 · Best for finance teams
Rho Business Banking
None on checking; savings yield via insured sweep; Rho Treasury nets 3.19-4.39% ($100k minimum)
$0
None (incorporated US entities only)
Everything is free, including same-day ACH, domestic wires with $2 million daily limits, full AP automation, and expense management that rivals charge per-seat for. The savings sweep insures up to $75 million across program banks, the highest coverage in the category. Built for multi-entity structures and companies where a finance team has replaced the bookkeeper.
#5 · Best chartered bank for startups
Grasshopper Bank Innovator Business Checking
1.35% on $25k-$250k; 1.00% below $25k and above $250k
$0
$100
A directly chartered digital bank, no partner-bank middleware, with a dedicated Accelerator Checking tier for VC-backed startups paying up to 3.00% with unlimited 1% debit cashback and founder office-hours support. ICS sweep extends FDIC coverage to $125 million. The conservative pick for founders who lost sleep during the BaaS meltdowns.
#6 · Best for bootstrapped startups
Bluevine Business Checking
1.5% on balances up to $250,000 (Standard, with activity); up to 3.7% on Premier
$0 (Standard)
None
Before you raise, Bluevine's free Standard tier pays 1.5% on up to $250,000 with an activity hurdle any operating business clears by accident, and FDIC coverage runs to $3 million. Mercury and Brex make you wait for $250k or accept fund yield before idle cash earns; Bluevine pays from dollar one.
Bottom Line
Open Mercury and you will not regret it; the free wires and software quality define the category. Layer Brex Treasury on top once there is real money to manage, or pick Ramp if you want your yield FDIC-insured rather than fund-based. Rho is the graduation account for multi-entity companies, and Grasshopper is the answer when the board asks why your bank is not actually a bank. Bootstrappers should just take Bluevine's 1.5% and keep building.
