Pros & Cons

Brex Card

Pros

• No personal guarantee and no advertised personal credit pull; company is the obligor
• $0 card annual fee and unlimited employee/virtual cards on Essentials
• Exclusive category points with no published earn cap; Brex Travel portal at 1¢/pt
• Native expense controls, virtual/vendor cards, and accounting integrations
• Local-currency cards in 50+ countries (plan-dependent); business-bureau reporting without personal-credit reporting (per Brex)

Cons

• Charge card: no revolving APR, no 0% working-capital window; late fee 2.99% or $38 after 30 days past due, plus possible 10% workout fee
• Sole props ineligible; funded startups commonly ~$50k cash; commercial revenue floors are messy
• “No FTF” marketing vs up to 3% FX markup
• Cash redemption 0.6¢/pt; airline transfers 1,500:1,000; Exclusive/contract multipliers are easy to misread
• Dynamic limits can fall with cash; Capital One ownership may change terms

Marriott Bonvoy Business® American Express® Card

Pros

• $125 fee with an automatic annual Free Night (≤35,000 points) that can exceed the fee if redeemed against a high cash rate
• Complimentary Gold Elite + 15 ENCs without 25 paid nights
• 4X on four real small-business categories (worldwide restaurants, U.S. gas, U.S. wireless, U.S. shipping) with no published cap
• Up to 99 employee cards at $0 with limits and alerts; $0 FTF
• Apply-to-decision path that does not hit personal credit unless the Card is accepted

Cons

• $125 fee with no statement-credit offset; 35k Free Night cap plus dynamic pricing and resort fees
• Points are Marriott-locked; airline transfers are 3:1
• Purchase APR 19.49%–28.49% variable and no 0% intro — a poor revolver
• Personal / joint-and-several liability
• No lounge access, no Global Entry/TSA credit, thin trip-insurance stack vs premium Amex business cards

Verdict

Brex Card

Brex is a charge-card ops platform owned by Capital One as of April 7, 2026 — not Spark, not Ramp’s Visa SKU, and not a revolving bank card. Pick it for no-PG underwriting and policy tooling. Do not assume 1¢ cash, a guaranteed 7x, or true $0 FX. Sole props, revolvers, and simple 1.5–2% cash shoppers should use a traditional PG card or Ramp if the cash bar fits. The Sep 2026 $1,000 / $4,000 / 30-day credit expires Sep 30 — re-check Oct 1.

Marriott Bonvoy Business® American Express® Card

This is the live U.S. Marriott business cobrand — not Bevy/Brilliant, not Chase Marriott Business (closed to new applicants), and not the Canadian $150 / 5X/3X/2X card. It pays when the firm actually sleeps Marriott and uses the Free Night. A hotel-agnostic shopper should use Ink Preferred, Business Gold, or a $0 2% cash card instead. Do not put Bonvoy member-stay points in the card earn column.
