Costs & Pricing

Metric	Brex Card	Fintech Platform Charge Cards
Annual fee	$0 published for the card. Software is separate: Essentials $0/user/mo; Premium $12/user/mo; Enterprise/Smart Card custom. Do not treat Premium as a card AF unless the company elects that plan.	CATEGORY: Almost always $0 on public pages. EXAMPLE A Engine X: $0. EXAMPLE B Rho: $0. Adjacent Coast: platform fee $4 per active user / month (not a classic card AF).
Employee card fee	$0; unlimited physical + virtual cards advertised	CATEGORY: Usually $0. EXAMPLE A: $0; unlimited physical + virtual (marketing). EXAMPLE B: $0; unlimited physical + virtual.
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.	CATEGORY: Usually absent — charge products, no revolving purchase APR. Marketing “0%” is almost always charge-card float, not a 12–18 month 0% intro APR. EXAMPLE A: N/A / not published. EXAMPLE B: None (paid in full Daily or Monthly).
Intro APR (purchases)	Not offered	CATEGORY: Not offered as classic intro APR. EXAMPLE A: not offered. EXAMPLE B: Daily = next-day debit; Monthly ≈ 30-day float — not intro APR.
Foreign transaction fee	Marketing: no FTF. Official: FX rate markup of up to 3% on conversions (Mastercard wholesale, adjusted daily). Local-currency cards can avoid conversion on local spend.	CATEGORY: Often missing from marketing; live in ToS / bank addendum. EXAMPLE A: silent on product page as of 3 Sep 2026 — dedicated Engine X bio extracts Program Terms FTF $0 (prefer Program Terms / dedicated bio). EXAMPLE B Rho: CONFLICT — help center says no FTF; ToS §2.4 may charge up to 1% on foreign transactions; network conversion may still apply. ToS wins. Adjacent Coast: 2.5% after USD conversion.
Late payment fee	2.99% of delinquent balance or $38, whichever is higher, assessed once per statement that is 30 days past due (Card Program Terms, Apr 7, 2026)	CATEGORY: Often not on marketing page. EXAMPLE A: not boxed on product page; dedicated Engine X bio extracts $40 per late payment from Program Terms eff. 4/1/2026. EXAMPLE B Rho: 3% of delinquent balance per month, up to 6 months, unless prohibited by law (ToS §2.4) + forfeit cash back for that period. Adjacent Coast: greater of 2.5% of past due or $35; after 31 days greater of 5% or $35.

Rewards & Value

Metric	Brex Card	Fintech Platform Charge Cards
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.	CATEGORY: Varies widely; rarely as simple as Spark uncapped 2% cash. EXAMPLE A Engine X: 1.5% back in Engine points on everyday / off-Engine purchases. EXAMPLE B Rho Standard: 1.25% Daily Terms / 1.00% Monthly Terms. Adjacent Coast: fleet rebates + non-fuel ~1% (collect from Coast rewards page).

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.	EXAMPLE A Engine X (live as of 3 Sep 2026): 20,000 Engine points after activate + spend $2,000 in the first 30 days. Conflict — Fit Small Business (14 Jul 2026) adds off-platform qualifier; open engine.com/x/spend-incentive-terms. No hard expire date on public hero. EXAMPLE B Rho: no live dollar welcome on official product page as of 3 Sep 2026; NerdWallet (26 Aug 2026) still shows $500 — secondary/possibly stale.
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.	EXAMPLE A: points redeemable for flights, hotels, cars, statement credits via Engine; ¢/point Not disclosed; points have no cash value — do not assume 1¢. EXAMPLE B: statement credit at 1¢ per 1% after full on-time pay; must redeem within 12 months or forfeit (Rho will not notify); Daily Terms cash back typically posts around the 6th business day of the following month.
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.	Generally not offered in the Chase/Amex bank-card sense. Engine redemption is platform catalog. Rho is cash back.

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

• 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

Fintech Platform Charge Cards

Pros

• $0 annual fee and $0 extra-card fee on Engine X and Rho (official pages, 2026)
• No personal guarantee; Engine and Rho state no personal hard pull (apply/FAQ)
• Engine X 6–10% points on Engine hotels/cars is a real category rate if that booking path is used
• Rho publishes cash-back math, exclusions, $1M cap, and 12-month redeem-or-forfeit
• Both issue virtual + physical cards with pre-spend controls; Engine decision timing published (24 hours typical)

Cons

• Not sole-prop products (Engine official; Rho commonly reported)
• Pay-in-full; Rho late fee 3%/month up to 6 months + rewards forfeiture
• Engine point cash value unpublished; 10% is not 10% cash
• Rho up to 2% is conditional (Platinum + Daily + on-time + domestic eligible MCCs)
• Insurance / lounge / Schumer-box items largely missing from public card pages; Engine FTF and late fee not boxed on /x

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.

Fintech Platform Charge Cards

CATEGORY PATTERN — not one SKU. EXAMPLE A Engine X is also a dedicated bio in this set (prefer that page for Engine-only vs pages). EXAMPLE B Rho is the smaller banking-plus-card peer. Adjacent Coast is fleet-only. Measured against Ramp/Brex/Divvy, not a substitute for them. Anti-fit: sole props, 0% intro APR borrowers, and anyone treating up to 10% or up to 2% as unconditional cash. Re-verify welcome offers, FTF, and fee addenda before publish.
