Dufour Aerospace

Its first product, the Aero-200, takes off and lands like a helicopter and flies like an airplane, carrying 20 kg over 200 km, or further with less payload, using a serial hybrid-electric engine and an in-house flight computer. DufourOS lets operators supervise fleets remotely from central control centres, for route-based cargo, surveillance, inspection and mapping, in civilian and dual-use roles. The founders draw on more than 30 years in commercial helicopter operations, and the company has a technology office in Zurich.

The 2025 Battery Report lists Dufour among major battery-electrified aviation players in Europe (eSTOL/eCTOL).
