## About

Based in Paris, France, and founded in 2021 and led by CEO Thomas Hiriart,  Ion-X SAS operates as a manufacturing company providing advanced propulsion systems for small satellites, focusing on technology to support the increasing demand for satellite constellations in Low Earth Orbit (LEO). In December 2024, ION-X raised EUR 13 million in Series A funding from InnovaCom, with TechnoFounders, Expansion Ventures, and European Innovation Council participation.

Ion-X SAS provides HALO-100X, which is a 1U plug-and-play thruster leveraging non-toxic, inert, and non-pressurized ionic liquid, designed to improve satellite operations, and propulsion efficiency, and extend operational lifespans. Its thruster delivers high thrust-to-weight ratios and superior specific impulse (ISP). It allows operators to adjust thrust for various orbital maneuvers, including orbit injection, station-keeping, debris avoidance, and end-of-life deorbiting. The company’s product design reduces dependency on external cathodes and ensures stealth operation with lower emissions.  

The company plans to use the funding from December 2024 to accelerate development and expand the production of electrospray thrusters for small satellites and constellations. Also, it plans to begin producing 10 thrusters per month by 2026, building up to 200 thrusters per year by 2028.
