Harbinger, a Garden Grove, California, company that builds electric and hybrid medium-duty vehicle platforms, raised $240m in a Series D round announced on 5 November 2026.
Tiger Global, Capricorn's Technology Impact Fund and Ridgeline, a defense-focused investor, co-led the round. Fidelity Management & Research Company, Squarepoint Capital and Xantium came in as crossover investors. Returning backers included Maniv, Greycroft, Australian Gulf Capital, PanaceaVC, ArcTern Ventures and Leitmotif, a firm backed by Volkswagen according to TechCrunch. FedEx and THOR Industries invested as strategic backers through TechNexus, and BuildGroup joined as a strategic investor with a focus on data centers. Goldman Sachs and Morgan Stanley were placement agents.
Harbinger did not disclose a valuation. The company said it has now raised more than $650m in total.

What Harbinger does
Harbinger started out developing a single electric chassis for medium-duty trucks. TechCrunch reported that the company was set up by former employees of Canoo, the EV maker that has since shut down, and of battery developer QuantumScape. The sources differ on when: Harbinger's announcement gives 2021 as its founding year, while TechCrunch puts it at 2022.
Its line-up now includes hybrid versions. FreightWaves reported that the gasoline range extender on the HC Series Cab gives up to 500 miles of range depending on configuration and can supply up to 15 kW of power to outside equipment. Chief executive John Harris told FreightWaves the company had recently completed its 1,000th vehicle. Harbinger did not disclose its current production capacity.
Harbinger also sells an auxiliary power system called Industria, and its announcement named the trailer maker Airstream as the first customer for it.
FedEx as customer and investor
FedEx is Harbinger's main named customer. It has ordered 2,000 all-electric trucks valued at more than $300m, with deliveries due by the end of 2027, according to FreightWaves. Paul Melander, FedEx's senior vice-president of safety and transportation, has joined Harbinger's board.
The relationship began with a smaller deal. When Harbinger raised a $160m Series C in November 2025, FedEx placed an initial order for 53 trucks, FreightWaves reported, and TechCrunch said FedEx led that round. It returned for the Series D.
What the money is for
Harbinger said the new capital will pay for more medium-duty manufacturing capacity and for an expansion beyond commercial vehicles into energy storage, power generation, autonomy software and defense. It did not say how the money will be split between trucks and the newer businesses.
Some of that work is already under way. TechCrunch reported that Harbinger acquired the autonomy startup Phantom AI, is developing hybrid emergency vehicles and has shown a driverless hybrid electric platform for military use. FreightWaves said the company is building the platform for an uncrewed Army supply vehicle under a contract with American Rheinmetall; no contract value was disclosed, and such prototype programs usually run to between three and ten units.
"Harbinger exists to challenge what industry has learned to accept, and reinvent the critical systems the world depends on," Harris said in the announcement. Griffin Schroeder, a partner at Tiger Global, linked the bet to demand for power, describing electrification as one of the main constraints of the AI era.
A tough market for electric trucks
The round comes as US truck sales have fallen. FreightWaves, citing data from the clean-transport group CALSTART, reported that zero-emission models made up a record 4.14% of US truck deployments in the second half of 2025, but total truck sales fell 35% from a year earlier, and cargo vans accounted for 12,158 of the 12,996 new zero-emission units.
Harbinger's move into power systems and defense spreads its bets beyond delivery trucks. TechCrunch reported that the company is weighing a public listing; Harbinger has not announced any such plan.
