Brex

Brex is a spend management platform for businesses, combining corporate cards with expense management, bill payments, travel booking and business accounts. It is built to help finance teams control company spending in real time rather than reconcile it after the fact. Its origin story shaped its reputation. Brex launched with a corporate card for startups that did not require a personal guarantee from founders and based limits on the company's cash and funding rather than founders' credit scores, which made it a fixture among venture-backed startups. It has since focused on startups and larger enterprises, building a full finance platform rather than just a card. The platform's value is in controls and automation. Companies set spending policies and budgets by team, project or employee; cards can be issued instantly, both virtual and physical, with limits and merchant restrictions; receipts are captured and matched automatically; and AI features review expenses against policy and handle routine approvals. Bill pay and reimbursements run through the same system, and integrations with accounting software keep the books in sync. Global companies can issue cards and pay in many countries and currencies. Business accounts let companies hold operating cash and earn yield, positioning Brex as a primary financial platform rather than a peripheral tool. Revenue comes largely from card interchange plus software subscriptions for advanced features. The trade-offs are eligibility and fit. Brex's underwriting and product focus suit venture-backed startups and established mid-to-large companies; very small traditional businesses may not qualify or may find simpler tools adequate. Alternatives include Ramp, its closest competitor with a strong emphasis on savings and automation; Mercury for startup banking with cards; Navan for travel and expense; Airwallex for global accounts and spend; Expensify for expense reporting; and American Express corporate cards. Choose Brex when you want corporate cards and spend controls built for a growing, funded company, especially one operating internationally.
