Ramp is the best pick for most US small businesses — a free plan that includes the corporate card and AI agents for approvals, expense coding, and fraud detection, with lower eligibility requirements. Brex is the best pick for funded startups and fast-growing companies that need international use, higher limits, and card, banking, and spend in one platform — and it's now owned by Capital One. Both replace the shoebox of receipts and the end-of-month scramble to code transactions with a card and software that handle it as the spend happens.
The two, in one line each
Ramp is a corporate card and spend platform with a free plan and AI agents for approvals, expense coding, and fraud detection.
Brex is a corporate card, expense, and banking platform for funded startups and larger companies, owned by Capital One since April 2026.
Where each one actually wins
Ramp wins on accessibility and automation. Its Free plan is $0 per user and includes the card; Plus is $15 per user per month on monthly billing (about 20% less annually) plus a platform fee that isn't published. Its AI agents include a Policy Agent that auto-approves low-risk spend and escalates the rest, an Expense Coding Agent and Receipt Collection Agent, an Invoice Processing Agent, a Fraud Detection Agent, and a text-based agent employees can ask about expense policy. Third-party sources report eligibility of about $25,000 in a US business bank account and a US-registered corporation, LLC, or LP, with no personal guarantee.
Brex wins for funded or fast-growing companies with broader needs. Essentials is $0 per user, and Premium is listed at $12 per user per month. Its AI features include Brex Assistant for filling in receipts and categories, AI-powered custom rules, AI compliance audit detection on Premium and above, and automated general-ledger coding; an "agents" product is in early access behind a waitlist. Eligibility is stricter: Brex says it requires a US EIN, US incorporation, and a US address, with venture- or accelerator-funded startups needing a $50,000 minimum cash balance and commercial businesses generally needing over $500,000 in annual revenue.
One thing to know about Brex: Capital One completed its acquisition of Brex on April 7, 2026, valued at $5.15 billion. Brex says it keeps its own identity and platform with its co-founder as CEO, but future pricing and eligibility are worth watching.
If you're a US small business that wants a free card with strong automation, Ramp is the more direct fit. If you're a funded startup or a company with international spend, Brex is built for that.

FAQ
Can sole proprietors or freelancers get either card? Generally no — third-party sources report that both Ramp and Brex exclude sole proprietors, and both are built for incorporated US businesses. For freelancers, a simpler expense tool is usually a better fit.
Did Capital One really buy Brex? Yes — the deal was announced in January 2026 and Capital One completed it on April 7, 2026. Brex says it will keep operating as an independent platform under its own brand.
Is Ramp's free plan really free? The Free plan is $0 per user per month and includes the card and basic features. Plus adds paid features at $15 per user per month plus a platform fee, and Ramp lists a 3% foreign exchange fee per a third-party review.
Do I need a minimum bank balance? Both have eligibility requirements. Third-party sources cite about $25,000 in a US business bank account for Ramp. Brex's own eligibility page cites $50,000 minimum cash for venture- or accelerator-funded startups, with other paths based on revenue.
Can AI approve expenses on its own? Ramp's Policy Agent can auto-approve low-risk spend and escalate the rest, and Brex describes a review agent doing the same in early access. Setting your own policy limits is what keeps that safe.
