Traditional small business credit cards size limits around personal credit scores and company profitability. Many venture-backed startups have neither: founders may have thin personal credit files, and the company is often unprofitable by design during its growth phase. Brex is a corporate charge card built to underwrite companies on cash balance and funding history instead.
This review covers how the Brex card is structured, how spend and rewards work in practice, its fee mechanics, its eligibility rules, and its constraints. Brex operates in the United States only.
What the Brex card is structurally
The Brex card is a charge card, not a traditional credit card. The company must pay its balance in full each billing cycle, and there is no revolving balance or interest charge on unpaid amounts. Brex issues the card against a company’s cash balance and spend history rather than a personal guarantee.
Using the card requires an existing Brex banking relationship. Brex is not a chartered bank; deposit and banking services are provided through partner banks, with the card itself issued on the Mastercard network. The card functions as one part of a broader platform that also includes a business deposit account and an expense-management product called Brex Empower.
Card issuance and spend controls run through the Empower dashboard. Finance teams can generate individual virtual cards for specific vendors or projects, set spending limits per employee or department, and view all transactions in one place as they post.
How spend and rewards work in practice
Brex sets a company’s card limit using an underwriting model based on cash balance, funding history, and recent spend, rather than a fixed multiple of revenue or a personal credit check. Limits can change as a company’s cash position or funding status changes.
Card transactions earn multiplier points rather than flat cashback. The highest multipliers apply under “Brex Exclusive” status: 7x points on rideshare, 4x on travel booked through the Brex portal, 3x on restaurants, 2x on recurring software subscriptions, and 1x on all other spend. Brex Exclusive status requires meeting additional funding or revenue criteria set by Brex, separate from base card eligibility.
Points are redeemed for travel bookings, transferred to airline partners, or converted to statement credit. Each redemption path applies its own conversion value, so the return per point depends on how it is redeemed rather than a single fixed rate.
Empower also applies policy rules automatically at the point of purchase. A transaction that exceeds a category limit or is missing a receipt can be flagged for review without waiting for a monthly statement cycle.
Live budgets let a manager see a project’s running spend total as transactions post, rather than reconciling totals after the billing cycle closes. This shifts expense oversight from a monthly review to an ongoing one, though it does not change how or when the card balance is billed.
Fees and pricing mechanics
The Brex card carries no annual card fee. Brex’s core platform, called the Essentials plan, has no monthly subscription cost and includes card issuance and basic expense management.
A paid “Premium” tier adds features such as custom approval workflows and integrations with accounting systems like NetSuite or Sage Intacct, typically billed per user per month. An “Enterprise” tier is priced individually for larger organizations.
Brex funds these services primarily through interchange revenue, the fee merchants pay on each card transaction, rather than through card fees charged to the business.
Limits, eligibility, and availability
Brex is a charge card issued against a company’s cash balance and spend history, and the program is available only within the United States. Access to the card requires an existing Brex banking relationship; the card is not sold as a standalone product.
Eligibility criteria typically require the applicant to be a U.S.-registered business entity and to meet at least one financial threshold, such as a minimum balance in a Brex deposit account or a documented venture capital funding round. Certain established professional service firms, such as law or medical practices, can qualify under separate criteria.
The highest reward multipliers are limited to companies that hold Brex Exclusive status, which requires meeting additional funding or revenue criteria beyond base card eligibility. Companies that do not meet either the base eligibility or Brex Exclusive criteria may be directed toward other card programs or providers.
Tradeoffs, risks, and limitations
Reaching the highest reward multipliers requires routing all corporate card spend through Brex. A company that also uses a secondary card for part of its spend does not lose its base card, but it does not qualify for Brex Exclusive multipliers on that portion of spend or on its account overall, since the status applies at the account level.
Reward value depends on category concentration. A company whose spend falls mostly outside rideshare, travel, restaurants, and recurring software earns primarily at the 1x baseline rate, regardless of Brex Exclusive status.
Credit limits are not fixed. Because they are tied to cash balance and funding history, a decline in a company’s cash position or a change in its funding status can result in Brex lowering the card’s limit.
Brex’s banking services depend on partner banks rather than a Brex-held charter. A disruption at a partner bank, or a change in that partnership, can affect access to linked deposit or credit functions, independent of the underlying FDIC coverage on deposits.
The Brex website publishes current eligibility criteria, reward rates, and fee schedules, which are subject to change.
