Brex

Brex began as the corporate card startups could actually get — underwritten on cash in the bank instead of a founder's personal credit — and has since expanded into a full financial stack: business accounts, expense management, bill pay, travel, and an AI layer that does the receipt-and-memo drudgery automatically.

What we like

The consolidation story is genuinely strong. Cash sits in Brex business accounts earning treasury yield, cards draw against it with policy enforced at swipe time, and the AI assistant chases receipts, drafts memos, and codes transactions so reps barely think about expenses. Global support is a real differentiator: local-currency cards, international entities, and reimbursements in dozens of countries make Brex viable for companies whose operations outgrew US-only rivals. Underwriting remains founder-friendly — no personal guarantee — and limits scale with your balance.

Where it falls short

The best of Brex sits behind Premium at around $12 per user per month; the free Essentials tier is capable but visibly nudges you upward. The 2022 decision to drop tens of thousands of small-business customers on short notice still colors perceptions — Brex wants venture-scale customers, and bootstrapped SMBs should read that signal. Rewards are structured to reward going all-in on Brex, which is less attractive if you want to keep a traditional banking relationship.

Verdict

For venture-backed and global startups, Brex is one of the two obvious choices for the financial stack, and the banking-plus-cards integration is its edge. Run the comparison against Ramp — Ramp usually wins on free-tier spend management, Brex on banking and international reach — and pick the one matching your shape. Bootstrapped small businesses should look at Ramp or their bank first.
