Ascendance

About the Company

Hybrid-electric pioneers -- We're taking aviation to new heights.

Founded in 2018 by Jean-Christophe Lambert, Thibault Baldivia, Clement Dinel, and Benoit Ferran, Ascendance is a pioneering company in decarbonized aviation.

Based in Toulouse and supported by Bpifrance, the France 2030 program, and the Occitanie Region, the start-up is developing STERNA Hybrid Pack, an innovative hybrid-electric propulsion system that combines high performance, extended range, and a drastic reduction in emissions.

This propulsion system powers ATEA, a vertical take-off and landing (VTOL) hybrid-electric aircraft designed for regional air transport -- including passenger, cargo, medical, and security missions.

Through this approach, Ascendance is pursuing a dual ambition across both civil and defense markets, driving the transition towards sustainable aviation.
