Revoy

What Revoy does

Revoy is a San Francisco-based freight electrification company founded in 2020 by Ian Rust. It sells an "electrification as a service" product consisting of an electric battery dolly that hitches between a diesel semi-truck's tractor and trailer via a standard fifth wheel and a proprietary smart kingpin. The dolly carries a 525kWh LFP battery pack delivering up to 250 miles of electric driving range and reduces diesel power demand to roughly 10% of normal load, lifting fuel efficiency from 6-8 MPG to 20-35+ MPG (and 120 MPG in the all-electric portion of the Ryder demonstration). Rather than recharging, the depleted unit is swapped for a fully charged one at Revoy stations located along major US shipping corridors in under five minutes, with attendants performing the swap while drivers rest.

The technology stack integrates hardware (the dolly drivetrain, battery, smart kingpin, fifth-wheel coupling), physical infrastructure (swap stations with attendant service and driver amenities), and software (a mobile app for range, safety alerts, and swap reservations). The system is FMVSS-compliant and certified for US roads, and the company has built advanced safety features including blind-spot detection, rollover and jackknife auto-correction, and 30% shorter stopping distance. Revoy also publishes a savings calculator that maps emissions and dollar savings across routes such as NY-Miami, Denver-New Orleans, and LA-Chicago.

Revoy monetizes via usage-based per-mile fees under three published tiers: Basic (cost parity with diesel, for 1-4 truck owner-operators), Business (5% below diesel, for 5+ truck fleets), and Enterprise (10% below diesel, multi-year contracts with dedicated account management and driver analytics). The go-to-market is direct sales targeting fleet owners, owner-operators, and company drivers, with validation anchored on a year-long Ryder demonstration between Texas and Arkansas that achieved 94% emissions reduction. Headcount is 11-50, sourced from GM, Cruise, Amazon, Google, Ample, Tesla, Lucid, and Embark. Funding to date includes a Y Combinator-led seed in March 2022 (with Soma Capital) and a follow-on round in 2023 (with Eight Capital and Transition).

Revenue model

1. Electrification as a Service (Per-Mile): Customers pay for miles driven with the Revoy EV attached, avoiding upfront hardware costs. The model reduces a diesel truck's power demand to approximately 10% of normal load. Pricing tiers offer cost parity to 10% savings versus diesel depending on fleet size and commitment level.
2. Battery Swap Station Services: Revenue generated through battery swapping infrastructure at truck stops along major shipping routes. Attendants perform swaps while drivers rest, with amenities including free coffee, clean bathrooms, snacks, and driver lounge.

Core offering

Revoy manufactures and operates a battery-powered EV dolly that hitches between a diesel semi-truck's tractor and trailer to electrify long-haul freight. The system uses a 525kWh LFP battery providing up to 250 miles of electric range, with under-5-minute battery swaps at a network of company-operated stations along major shipping routes. Revoy sells this as 'electrification as a service' on a per-mile basis, allowing fleets to avoid the upfront cost and downtime of replacing diesel tractors with full battery-electric semis.

Product overview

Revoy offers an 'electrification as a service' solution for freight trucking, centered on the Revoy EV—a battery dolly that integrates with existing diesel semi-trucks via a standard fifth wheel and smart kingpin connection. The product portfolio includes the core Revoy EV unit, a network of Revoy Swapping Stations for battery replacement, and a Revoy Mobile App for drivers. The company provides three pricing tiers (Basic, Business, Enterprise) targeting owner-operators through corporate fleets, all built around a battery swap model that mimics traditional fuel stop operating patterns rather than requiring wholesale fleet replacement.

Direct peers

• Lightning eMotors: Lightning eMotors builds electric medium-duty commercial vehicles and fleet electrification solutions, including repowers and charging infrastructure. It overlaps with Revoy on the commercial fleet EV use case and offers a competing electrification pathway for fleet operators.
• Range Energy: Range Energy builds powered trailer/e-axle systems that electrify trailers attached to diesel tractors — nearly identical architecture to Revoy's EV dolly, targeting the same fleet electrification use case with hardware-integrated propulsion rather than a separate swap vehicle.
• Ample: Ample operates modular battery-swapping stations for EVs (initially passenger, expanding into commercial fleets). Revoy's truck-stop swap infrastructure and per-mile business model closely mirror Ample's approach, making it the closest operational analog in battery-swapping-as-a-service.
• Xos Trucks: Xos manufactures Class 6-8 commercial electric trucks and offers them through sales and 'Xosphere' fleet management. It competes with Revoy for the same fleet electrification budget, but via vehicle replacement rather than diesel retrofit.

Regional players

• WattEV: WattEV is building a public network of DC fast-charging stations for medium- and heavy-duty trucks along California freight corridors. It competes with Revoy's swap model by offering charging infrastructure, though its geographic focus is currently California-centric and its model requires long charge dwell times rather than swaps.

Emerging players

• Einride: Einride develops electric and autonomous freight vehicles plus a freight operating platform, primarily in Europe and the US. It targets the same sustainability-driven shipper demand that Revoy serves but with purpose-built EVs rather than diesel retrofit.
• Hyzon Motors: Hyzon produces hydrogen fuel cell and battery electric commercial trucks. It is a competing technology path for fleet decarbonization and competes for the same Class 8 customer RFPs that Revoy targets.
• Phoenix Motorcars: Phoenix Motorcars manufactures medium-duty electric trucks and EV chassis for commercial fleets. It competes in adjacent vehicle classes for the same fleet electrification dollars and serves as an alternative path to Revoy's diesel-retrofit model.

Broad incumbents

• Tesla (Semi): Tesla Semi is a purpose-built Class 8 electric truck from the dominant EV manufacturer. It represents the largest competitive threat to Revoy's fleet-electrification thesis by offering full vehicle replacement with mature OEM support and Megacharger infrastructure.
• Daimler Truck / Freightliner eM2/eCascadia: Daimler Truck's Freightliner and other OEM brands sell production battery-electric medium- and heavy-duty trucks. As an incumbent OEM, it competes for fleet electrification procurement and brings dealer/service networks that Revoy must match.
