Employee card fee	$0; unlimited physical + virtual cards advertised	$0 (CMA: Annual Fee for Additional Cards: None)
Purchase APR	N/A — charge card, pay in full. Marketing “0%” is charge-card float (daily ~1 business day after clear, or ~30-day monthly statement), not an intro APR.	19.49%–28.49% variable (Prime + 12.74% to Prime + 21.74%); placement by creditworthiness at account opening.

Rewards & Value

Metric	Brex Card	Delta SkyMiles® Gold Business American Express Card
Base earn rate	1x on everything else under Exclusive (1 point per $1 USD spend with a U.S.-based merchant). All customers enrolled in Exclusive unless the contract says otherwise. No published category caps. Non-Exclusive / second-card path may be flat 1x — source conflict with 2026 reviews; confirm on the live contract.	1 SkyMile per $1 eligible purchases
Welcome bonus	$1,000 USD statement credit after ≥$4,000 Qualifying Spend within 30 days of activation. Apply, be approved, and activate (first purchase) Sep 1–30, 2026 (legal offer revised Aug 10, 2026). Re-check Oct 1. Review sites still print 10,000 points after $3,000 in 3 months — not found as a current dated legal page.	Conflict across official pages. Delta business-cards page: limited-time 90,000 bonus miles after $6,000 eligible purchases in the first 6 months — offer ends November 4, 2026. Amex product page (same period): evergreen-style 60,000 after $4,000 in the first 6 months with no end date. Treat 90k/$6k through 11/4/2026 as the live limited-time public offer; 60k/$4k as the fallback. Apply-flow T&Cs win.
Redemption value	Brex Travel portal: 1 point = 1¢. Cash to Brex business account or statement credit: 1 point = 0.6¢ (admin must claim). Headline 7x rideshare is 4.2% cash only if Exclusive + cash path. Do not use 1¢ for cash.	Pay with Miles = 1.0¢ ($50 off per 5,000 miles on delta.com). Award travel is dynamic; TakeOff 15 improves award pricing ~15% on Delta-operated flights only (not partner-operated, not taxes/fees). Do not assume transfer-partner value — this card does not transfer.
Transfer partners	Emirates Skywards, Avianca LifeMiles, Singapore KrisFlyer, Air France-KLM Flying Blue, Aeromexico Club Premier, Cathay Asia Miles, Qantas Frequent Flyer at ~1,500:1,000. Crypto (BTC/ETH) appeared in older guides at 0.6¢ — not on the current official redeem page.	None. Currency is Delta SkyMiles, not Membership Rewards. No transfer-out to other airlines. Miles do not expire under Delta’s published policy; Delta may still deactivate an account and remove miles.

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

Delta SkyMiles® Gold Business American Express Card

Pros

• $0 year-1 fee then $150 — lowest annual fee in the Delta business lineup
• 1st checked bag free worldwide + 2nd bag free domestic (2026 add) can offset the AF in a few team trips
• 2X on uncapped restaurants plus capped U.S. shipping and U.S. digital/TV/radio ads
• $0 foreign-transaction fee and $0 employee cards (employee spend feeds the $10k flight-credit threshold)
• TakeOff 15 reduces Delta-metal award cost 15%

Cons

• Ongoing $150 AF with credits that are conditional, portal-locked, or enrollment-gated after renewal
• Miles are Delta-only — no Membership Rewards transfers
• No lounge, no GE/PreCheck credit, thinner insurance than Platinum/Reserve Business
• No 0% intro APR; carrying a balance is expensive (19.49%–28.49% as of 09/02/2026)
• Personal guarantee / joint and several liability; advertising 2X is MCC-narrow (media providers, not any marketing vendor)

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.

Delta SkyMiles® Gold Business American Express Card

This is the low-fee Delta business cobrand — not personal Delta Gold (supermarkets 2X), not Platinum/Reserve Business, and not Amex Business Gold (MR). Confirm the live apply-flow welcome (90k/$6k through 11/4/2026 on Delta vs 60k/$4k still on Amex’s product URL). Skip it if you will not fly Delta, want transferable points, need 0% float, or refuse a PG.
