ABOUT US
Our background
PREYSSE
Established in early 2025, PREYSSE company is located at Châteauneuf-sur-Cher airfield (LFFU) in the town of Serruelles, France. Our company is the heir to PREYSSE AVIATION, a small business established in 2017 that has grown discreetly yet effectively, over the years to prepare for its transformation. This evolution is the result of several years of behind-the-scenes research and technical development by its founders, leading to the maturation of long and complex projects in their fields of expertise: light aviation, space technologies, and engineering.
Our company focuses on two distinct markets: the light aircraft sector, a mature and well-established field, with the development and small-series production of a high-performance light aircraft, and the space technology market, a rapidly expanding area, where it develops thrusters for the satellite industry. In parallel, our company is committed to the development of technologies, embedded systems, and specialized software for the fields of space and aeronautics. Research and development form the essential driving force behind our activities. Additionally, we are expanding our portfolio by providing engineering and consultancy services.
In the realm of light aviation, our development strategy isn't about revolutionizing the design of subsonic small aircraft; it's about harmoniously integrating the best theoretical concepts with the most field-tested practical skills. We aim to soon launch an aircraft that is both safe and pleasurable to fly, cost-efficient, and high-performing. Our intention isn't to shake up a market that's already competitive and mature but to distinguish ourselves through superior performance and unmatched design and construction excellence.

Space Technologies
PREYSSE
Breaking into the space technology market demands substantial investment and extensive R&D work. Developing propulsion systems for satellites is a colossal scientific and technological challenge, an exciting human endeavor, and a project that captures a large portion of our resources.
As a "hybrid" company, straddling the line between a small business and a startup, we merge the agility and innovation capabilities typical of startups with the stability and technical expertise of a small business. This allows us to fully engage with our project. We keep our sights set on our mission, relentlessly pursuing excellence, knowing that only actual outcomes count. Our goal is straightforward: to launch satellite thrusters in the near future that stand out for their high performance, outstanding reliability, and groundbreaking innovation, all while providing a significant competitive advantage.
