Harbinger Secures $240 Million Series D as It Moves Into Defense and Battery Storage

Harbinger, the electric-truck startup founded in 2022, announced a $240 million Series D financing round on Tuesday. The new capital will fund the company’s expanding product line, which now includes battery-storage solutions and a driverless hybrid platform for military use. The round underscores Harbinger’s rapid evolution from a single-chassis EV maker to a diversified mobility and defense player.

The financing was co-led by Tiger Global, Capricorn’s technology-impact fund, and defense-focused venture firm Ridgeline. Returning investors included FedEx, which led the previous Series C, as well as Maniv, Greycroft and Leitmotif, a Volkswagen-backed VC. Fidelity Management also participated, marking its first foray into the pre-IPO startup. With the new money, Harbinger’s cumulative fundraising exceeds $650 million. FedEx deepened its partnership by appointing senior vice president of safety and transportation Paul Melander to Harbinger’s board of directors, and by placing a $300-plus-million order for 2,000 electric trucks.

Harbinger was launched by former engineers from the now-defunct Canoo and battery pioneer QuantumScape. The company’s initial focus was a single electric truck chassis, but it has steadily broadened its scope. In 2023 it acquired autonomy startup Phantom AI, began developing hybrid emergency-vehicle prototypes, and unveiled a driverless hybrid electric platform aimed at military applications. These moves illustrate a strategic shift toward high-margin, government-backed markets that complement its commercial fleet business.

The infusion arrives at a time when the electric-truck market is heating up, with major logistics firms seeking to decarbonize fleets. FedEx’s repeat investment and sizable order signal confidence in Harbinger’s technology and its ability to scale production. At the same time, the defense sector’s appetite for low-signature, electrified platforms offers a new revenue stream less sensitive to commodity price swings. Industry observers note that the combination of commercial and defense contracts positions Harbinger well for a potential public offering, a step the company is reportedly weighing.

For founders and investors, Harbinger’s trajectory highlights the value of building modular, multi-use platforms that can serve both civilian and government customers. The round demonstrates that capital can still flow to capital-intensive hardware ventures when they show clear pathways to diversified revenue. As Harbinger ramps up production for the FedEx order and refines its defense offerings, the market will watch whether the company can translate its broadened portfolio into sustained profitability and a successful IPO.
