ION-X - A revolutionary technology in the satellite propulsion market


Enable our customers to optimize the missions of their satellites in orbit

ION-X is a startup created in May 2021 by the venture builder Technofounders and the scientist Jacques Giérak, a world specialist in ion sources for nanoelectronics, with +30 patents filed and +35 years of research conducted at the CNRS.


Based on a patented electrospray technology, the ION-X ion liquid thruster is a real breakthrough for small satellite propulsion.


Initially developed in the 1980s for nanoelectronics applications, the focused ion beam technology provides particularly competitive performance, including twice the thrust of the state-of-the-art and 30% less fuel consumption.


In June 2022, ION-X secured €3.8 million in funding to support its R&D development, strengthen its team, and plan an in-orbit demonstration mission by the end of 2023.
