What AtoB does

AtoB (legal entity CElegans Labs, Inc.) is a San Francisco-based fintech founded in 2019 that builds payment infrastructure for the trucking and transportation industry. Its core product is an open-loop fleet fuel card issued on Mastercard and Visa rails through partner banks (Celtic Bank, Community Federal Savings Bank, with Highnote powering commercial card issuance), accepted at 99%+ of US gas stations and 4,200+ truck stops. The platform has expanded into a broader spend-management suite: credit and prepaid fleet cards (AtoB Flex and AtoB Unlimited), a Business Expense Card with 1% cash back, a coming-soon Driver Payroll Card, telematics-linked fraud prevention with a $250,000 guarantee, IFTA automation, AI spend insights, Experian credit reporting, instant 24/7 carrier payouts via RTP/Zelle/Venmo/PayPal, fleet credit solutions, EV charging payments, and a Carbon Neutral program.

AtoB monetizes through a layered mix: per-card subscription fees ($3–$15/month plus $35 setup), interchange and discount spread on fuel transactions administered through cost-plus and retail-minus pricing on its 30,000+-station network, instant payment processing fees (typically a flat $25 or up to 1% configurable per partner), partner revenue share on every swipe through factoring and freight broker programs, and interchange-funded cash back. Go-to-market combines a self-serve online application (5-minute form, instant pre-qualification) for SMB and owner-operator fleets, an inside-sales motion with dedicated account managers for mid-market and enterprise fleets, and three channel programs — factoring referral, freight broker embedded platform, and merchant discount network — that distribute co-branded white-labeled cards and embedded financial services to fleets AtoB would not reach direct. Customers include 35,000+ fleets across local, OTR, and mixed operations, plus 45+ partners including Uber Freight, Schneider, Murphy USA, RaceTrac, Maverik, Sheetz, Circle K, Casey's, Exxon/Mobil, Sunoco, and TA/Petro. AtoB has raised over $125M cumulatively, including a $130M combined Series C equity and debt round in September 2024 co-led by General Catalyst and Bloomberg Beta with Mastercard as a strategic investor, reaching an $800M valuation and reporting 500% YoY revenue and volume growth at the time of the raise.

Revenue model

1. Card subscription and account fees: Monthly per-card fees plus one-time account setup fees. AtoB Flex charges $15/month for 1-5 cards and $3/month per additional card; AtoB Unlimited charges $3 per active card per month; both charge a $35 account setup fee and a $3/month AtoB Premium add-on fee.
2. Interchange and discount spread on fuel transactions: Revenue generated from the difference between merchant wholesale fuel cost and retail price (cost-plus and retail-minus structures) on the AtoB discount network across 30,000+ stations, administered on customer statements and settled through Visa/Mastercard rails.
3. Instant payment processing fees: Fees on instant carrier payouts, typically a flat $25 or up to 1%, configurable per factoring or broker partner.
4. Partner revenue share and card-issued spread: Revenue generated from factoring partners and freight brokers on every swipe of co-branded fuel, business expense, and driver payroll cards; AtoB retains a share of fees earned per gallon and per non-fuel purchase.
5. Cash-back funded interchange: Business Expense card offers 1% cash back on all purchases funded by interchange economics; factoring partners earn 0.5% on every non-fuel purchase.
6. Debt and equity capital financing: Combined Series C equity and debt funding of $130 million in September 2024 led by General Catalyst and Bloomberg Beta, with participation from Mastercard and trucking/logistics industry players, supporting growth and capital product offerings.

Broad incumbents

• WEX Inc. WEX is the largest US fleet card and corporate payments provider with deep enterprise fleet relationships and international fuel acceptance. AtoB explicitly competes against WEX in its own comparison content; WEX has the established scale, but AtoB positions itself as the modern, telematics-linked alternative.
• FleetCor Technologies: FleetCor is the public parent company of Comdata, Fuelman, and other fleet card brands and operates a global fuel card and corporate payments platform. It is the largest incumbent in the segment AtoB is attacking, with the scale to bundle fuel, lodging, and toll products.

Direct peers

• Comdata: Comdata is a long-standing trucking-focused fleet card and payments platform (owned by FleetCor). It directly competes with AtoB in OTR fuel cards, fleet spend management, and freight factoring integrations; AtoB customers cite Comdata's confusing invoices and outages as the reason for switching.
• Fuelman: Fuelman is a FleetCor-owned fleet fuel card targeting small and mid-market fleets with a focus on local gasoline discounts. It is one of AtoB's most commonly compared alternatives and a direct competitor in the SMB fuel card segment.
• EFS (eFueling Solutions): EFS is a private fleet card provider specializing in over-the-road trucking and truck stop acceptance. It competes with AtoB on truck diesel discounts and OTR fleet credit products, and AtoB mentions EFS as a direct comparison in its SEO content.

Emerging players

• RoadFlex: RoadFlex is an emerging fleet fuel and expense card provider targeting SMB and mid-market fleets with modern technology. AtoB explicitly compares against RoadFlex in its competitive content, indicating overlapping customer profiles and product positioning.
• Brex: Brex is a corporate card and spend management platform that has expanded into vertical-specific use cases including fleet and logistics. While broader in scope than AtoB, it competes for the same mid-market customer's commercial card wallet and underwriting relationship.
• Motive (formerly KeepTruckin): Motive is a fleet management and telematics platform with growing spend and payments products for trucking fleets. It is comparable to AtoB on the telematics and fleet data side (Samsara-equivalent integration target) and increasingly competes on the spend management layer.
• OTR Capital: OTR Capital is a freight factoring company offering same-day and instant carrier payments with embedded card products. It is comparable to AtoB on the factoring partner program side and competes for the same carrier relationship in the instant-payments vertical.

Others

• Highnote: Highnote is the card-issuing platform that powers all AtoB commercial Mastercard products. It is an enabler/infrastructure peer — a technology partner whose embedded finance capabilities are core to AtoB's product surface rather than a direct competitor.
