Mercury — best for tech startups that need API integrations, virtual cards and a high-yield treasury account for automation and investor workflows; note Mercury operates via fintech bank partners rather than as a traditional bank.

Bluevine — best when your priority is earning interest: high-yield checking/savings and built-in invoicing on qualifying balances; strong for yield-conscious startups but less focused on advanced card/API tooling.

To help narrow down the best choice, tell me:
If you want **online-only business banking specifically built around startups**, I’d compare these three: Service | Particularly useful for | Notable features --- | --- | ---
If you want online-only business banking specifically built around startups, I’d compare these three:
| Service | Particularly useful for | Notable features |
|---|---|---|
| Mercury | Early-stage and VC-backed startups | Free checking/savings, virtual & physical cards, multiple accounts, free ACH/domestic & USD international wires, accounting integrations, API/CLI access, and venture debt. Mercury Mercury Support |
| Brex | Funded startups with substantial spending | Banking + treasury + corporate cards + bill pay + reimbursements, automated expense controls, global payments, and up to $6M FDIC coverage through its program banks. Brex Brex |
| Relay | Bootstrapped/small startups wanting detailed cash organization | Up to 20 checking accounts, savings, role-based access, QuickBooks/Xero integration, bill pay, and separate accounts for taxes, payroll, expenses, etc. Relay Relay |
One important distinction: these are fintech platforms rather than traditional brick-and-mortar banks. For example, Mercury says its banking services are provided by partner banks, while Relay's banking services are provided by Thread Bank.
If you tell me whether your startup is bootstrapped or VC-funded, approximate monthly spend, and whether you'll have employees, I can compare the relevant options on fees, FDIC coverage, cards, international payments, accounting integrations, and cash yield.
If you want **online-only business banking with startup-friendly features**, I’d put **Mercury** at the top of the list. ### Best options - **Mercury — Best overall for startups**
If you want online-only business banking with startup-friendly features, I’d put Mercury at the top of the list.
Mercury — Best overall for startups
$0/month for core business checking and savings
No minimum balance
Free ACH and domestic USD wires
Virtual/physical cards, expense controls, reimbursements and approval workflows
Invoicing, bill pay and accounting integrations
Particularly strong for startups with employees, vendors, investors, or international payments.
Relay — Best for cash-flow organization
Free Starter plan
Up to 20 checking accounts, which is excellent for separating taxes, payroll, operating expenses, profit, etc.
Strong bill-pay, expense-management and accounting features
Paid tiers add approval workflows, automation and higher limits.
Novo — Best for a simple small business
$0 monthly fee and no minimum balance
Free standard ACH
40+ integrations including Stripe, Shopify, QuickBooks, Square and Xero
Especially attractive if you're a solo founder or service business rather than a venture-backed startup.
For a typical startup: Mercury. It has the strongest combination of banking, cards, expense management, payments, invoicing, accounting and potential access to startup financing—all without requiring a monthly fee for the core account.
One caveat: these are fintech platforms rather than traditional branch banks. For example, Mercury says its banking services are provided through partner banks, while Relay likewise identifies itself as a financial technology company.
If you tell me whether you're a solo founder, LLC, or C-corp, roughly how much you'll keep in the account, and whether you'll have employees/investors, I can narrow this down to the best 1–2 choices for your situation.

For online-only business banking tailored to startups, a few standout financial technology platforms operate in partnership with insured chartered partner banks. The "best" choice really depends on whether your startup is venture-backed or bootstrapped.
The top recommendations specifically built for startup needs include:
Mercury is widely considered the default banking choice for tech and VC-backed startups.
Relay (partnered with Thread Bank) is heavily praised for cash-flow management and clean separation of operating expenses.
Brex combines a high-limit corporate card system with an embedded business cash account and bill pay. (Note: Brex operates under Capital One's ownership umbrella following its acquisition).
If your startup is sitting on cash reserves that you want to keep liquid while earning interest, Bluevine is a strong contender.

If you mean **U.S.-based online-only business banking**, I’d put these three at the top of the list: - **[mercury.com](https://mercury.com/?utm_source=chatgpt.com) — Best overall for startups.** Free checking/savings, virtual and physical cards, free USD wires, bill pay, invoicing, accounting integrations, treasury,…
If you mean U.S.-based online-only business banking, I’d put these three at the top of the list:
Mercury would be my default choice for a typical tech startup. It combines banking, cards, payments, invoicing, accounting automation, treasury, and startup perks in one platform without a monthly account fee.
If your startup is already spending heavily and you care most about corporate cards + expense controls, I'd lean Brex. If you're bootstrapped and want separate accounts for taxes/profit/payroll, I'd lean Relay.
One important caveat: these are fintech platforms rather than traditional banks; the actual banking services and FDIC insurance are provided through partner institutions, so I'd check the current eligibility and insurance structure before depositing substantial funds.
If you tell me (1) your country, (2) whether you're bootstrapped or VC-funded, and (3) roughly how much you'll keep in the account, I can narrow this to the best 1–2 options.
