Harbinger develops electric vehicle chassis platforms specifically designed for medium-duty commercial, emergency, and recreational vehicle manufacturers. Based in Garden Grove, California, the company focuses on providing foundational EV architecture that enables original equipment manufacturers to electrify their fleets across diverse applications including delivery trucks, emergency vehicles, and specialty recreational vehicles. By targeting the medium-duty segment, Harbinger addresses a critical gap in the commercial electrification market where standardized, purpose-built EV platforms remain limited. The company's chassis-focused approach allows vehicle manufacturers to accelerate their transition to electric powertrains without developing underlying EV architecture in-house, positioning Harbinger as an enabling technology provider in the expanding commercial electrification ecosystem.
