Ampaire, a Long Beach, California-based aviation company developing hybrid-electric propulsion systems, has raised $19 million in Series B funding, bringing its total capital raised to $68 million.
The round was led by DiamondStream Partners, with participation from Alaska Star Ventures, IAGi Ventures, Pay it Forward Ventures, Massive Ventures, Techstars Ventures, Autodesk Foundation Impact Fund, Los Angeles Cleantech Incubator Impact Fund, Elemental Impact, Venn10 Capital, Gaingels, Exit Fund, Sand Hill Angels, and Climate Capital.
Accelerating Commercial Deployment
Ampaire plans to use the fresh capital to accelerate the commercial deployment of its hybrid-electric propulsion technology and expand its engineering and operational teams.
The company will also use the capital to broaden commercial route flights under the FAA’s eIPP program, strengthen supplier readiness, develop early manufacturing capabilities, prepare aftermarket support operations, and advance certification efforts.
These include Part 33 certification for the AMP-H570 hybrid-electric power system and Part 23 Supplemental Type Certification for the Eco Caravan aircraft.
Developing Hybrid-Electric Aircraft
Led by Co-Founder and CEO Kevin Noertker, Ampaire is developing hybrid-electric propulsion systems designed to reduce fuel consumption, emissions, and operating costs for regional aviation.
Its technology portfolio includes the AMP-H570 integrated-parallel hybrid-electric power system and the Eco Caravan, a hybrid-electric aircraft based on the Cessna Grand Caravan platform.
The AMP-H570 is designed to retrofit existing aircraft, with Ampaire targeting significant reductions in fuel consumption through hybrid-electric propulsion.
More Than 38,000 Hybrid-Electric Test Flight Miles
Ampaire operates a fleet of full-scale hybrid-electric aircraft that have completed more than 38,000 hybrid-electric test flight miles.
The company is also participating in the Federal Aviation Administration’s eVTOL Integration Pilot Program (eIPP), which is intended to support the development and integration of emerging advanced air mobility technologies.
Ampaire’s hybrid-electric systems are also being explored for aircraft auxiliary power unit (APU) applications, including systems used while aircraft are on the ground.
Moving Toward Commercial Readiness
With its latest Series B financing, Ampaire is focused on moving its hybrid-electric propulsion technology from flight testing toward commercial deployment.
The company plans to continue advancing the AMP-H570 and Eco Caravan while building manufacturing and supplier capabilities needed to support future commercial operations. Its customers and partners include airlines, cargo operators, and government organizations.
