The California industrial technology company has now raised more than $650 million as it expands its manufacturing platform into energy storage, autonomous vehicles and defense.
Harbinger has raised $240 million in a Series D co-led by Tiger Global, Capricorn's Technology Impact Fund and Ridgeline.
The financing, announced November 5, brings the Garden Grove, California-based company's total funding to more than $650 million since its founding in 2021.
Additional investors include Fidelity Management & Research Company, Squarepoint Capital, Xantium, FedEx, Greycroft and Leitmotif.
Harbinger originally focused on electric and hybrid platforms for medium-duty commercial vehicles. It is now positioning itself as a broader industrial technology company, developing systems for transportation, energy storage, power generation, autonomous vehicles and defense applications.
The company did not disclose its latest valuation.
A $300 Million Order From FedEx
One of Harbinger's most significant commercial developments is its expanding relationship with FedEx.
The logistics company has placed an order for 2,000 all-electric Harbinger trucks valued at more than $300 million, with deliveries planned by the end of 2027.
FedEx also participated in the latest funding round, while its senior vice president of safety and transportation, Paul Melander, joined Harbinger's board.
The order represents an important test for the company.
Unlike software businesses, industrial technology startups must manufacture physical products at scale, deliver them reliably and support customers throughout the equipment's operating life.
A large customer contract provides evidence of demand, but the revenue depends on successfully manufacturing and delivering the vehicles.
Beyond Commercial Trucks
Harbinger designs and manufactures critical electrification components, including batteries, drivetrain systems and vehicle platforms.
Its strategy is to reuse those technologies across multiple industries rather than develop separate engineering systems for every product.
The company has expanded into off-grid energy systems and power storage, with applications ranging from recreational vehicles to industrial infrastructure.
It has also entered the autonomous vehicle market through its acquisition of Phantom AI and announced work on unmanned hybrid-electric platforms for defense applications.
These moves expand Harbinger's addressable market beyond commercial trucking.
They also position the business to sell electrification technology into industries requiring reliable mobile power, industrial automation and autonomous operations.
Building an Industrial Technology Platform
Harbinger is led by co-founder and CEO John Harris, who previously worked at companies including Anduril, Boeing and Faraday Future.
The company emphasizes vertical integration, controlling engineering and manufacturing rather than relying entirely on third-party suppliers.
That strategy can improve control over product performance and production costs, but it also requires significant capital.
Manufacturing facilities, inventory, engineering teams and customer support create financial obligations that software companies often avoid.
The Next Test Is Execution
Harbinger plans to use the Series D to increase production capacity and support expansion into its new markets.
The opportunity is substantial, but diversification creates additional operational complexity.
Commercial vehicles, military systems and industrial power products have different customer requirements, procurement processes and product lifecycles.
Harbinger has not publicly disclosed revenue, gross margins or profitability.
Its next milestone is demonstrating that its vertically integrated manufacturing approach can support multiple product categories while fulfilling major customer orders.
At more than $650 million raised, investors are backing Harbinger to become something larger than an electric truck manufacturer: a supplier of critical industrial technologies.
