Leading the clean space era
Sustainable propulsion service, for all space asset operators.

About ExoSat
We are redefining the future of space by building a clean space, where sustainability is no longer optional but necessary - because it pays off.
ExoSat was founded by a French-German team of three space enthusiasts. We believe that space must become a circular economy to keep thriving and delivering important services to all of us on Earth.
We develop a disruptive low cost propulsion solution, while fighting the huge threat of space debris at the same time.
By integrating circular economy principles into space operations, we aim to ensure long-term orbital sustainability and contribute to preserving Earth's orbital environment for future generations.
Space is critical but faces propulsion challenges

active satellites in orbit
Satellites in orbit enable global communication, precise navigation, Earth observation, and weather forecasting, while also advancing scientific research and strengthening national defence.
average propulsion budgets
Propulsion costs cover R&D, hardware, propellant, integration, and launch. For SmallSats, these costs can climb up to 25%, underscoring the significant financial challenges operators face.

Explore our services
The demand for advanced propulsion systems continues to grow, and the need for innovative and cost-effective solutions becomes increasingly urgent.
But not only are we disruptive and low-cost: we are fully sustainable.
Propulsion services in orbit
Our orbit maintenance and adjustment service ensures satellites remain in their designated orbits, optimising performance and extending operational lifetimes.
Using advanced propulsion technology, we provide low-cost propulsion-as-a-service delivered by our fleet of sustainably powered satellites. Using our service, space asset operators save on expensive hardware and propellant. This includes all key operations: Station-keeping, orbit adjustments, collision avoidance, end-of-life disposal, etc.
This tailored solution is ideal for satellites in Low Earth Orbit, ensuring uninterrupted service and mission success.
