US-based electric and hybrid commercial vehicle manufacturer Harbinger has raised $240 million in Series D funding to expand its operations across electric vehicles, energy storage, power generation, autonomous driving and defence technology.
The funding round was co-led by Tiger Global, Capricorn’s Technology Impact Fund and Ridgeline. Other investors included Fidelity Management & Research Company, Squarepoint Capital, Xantium, Maniv, Greycroft, Australian Gulf Capital, PanaceaVC, ArcTern Ventures, Leitmotif, FedEx, THOR Industries through TechNexus and BuildGroup.
With this latest investment, Harbinger has raised more than $650 million since its founding in 2021.
The company will use the fresh capital to increase manufacturing capacity for its medium-duty electric trucks while developing new business areas. Its expansion comes as it works to fulfil a major order from FedEx for 2,000 electric trucks worth more than $300 million. Deliveries are expected to be completed by the end of 2027.
“Electrification is at the core of everything we do, and increasingly, electrification is at the core of industry, defense, mobility, and AI,” said John Harris, Harbinger’s co-founder and CEO, in the release.
“Harbinger’s role is not simply to give customers another option,” Harris said. “It is to reset expectations for what critical systems should deliver.”
Harbinger currently manufactures Class 4, Class 5 and Class 6 commercial vehicle chassis in all-electric and plug-in hybrid versions. The company develops its own powertrain, battery systems, steering and braking technologies.
In March, Harbinger introduced its HC Series Cab, which includes a gasoline range extender offering a driving range of up to 500 miles, depending on the configuration. The vehicle can also provide up to 15 kilowatts of exportable power, allowing businesses to operate equipment without needing a separate generator.
Beyond commercial vehicles, Harbinger is expanding into defence and autonomous technology. The company acquired autonomy software developer Phantom AI and has secured its first defence project through a contract with American Rheinmetall to develop a vehicle platform for an uncrewed US Army supply vehicle.
Harbinger has also started selling its battery technology for energy storage applications, creating additional opportunities beyond the commercial vehicle market.
The latest funding follows its $160 million Series C round in November 2025, when FedEx placed its initial order for 53 electric trucks. The new investment will help Harbinger increase production and develop its wider industrial technology business.
Led by CEO John Harris, Harbinger aims to build on its in-house vehicle engineering and manufacturing capabilities to serve multiple industries, including transportation, energy and defence.
