Key people at ienai SPACE.
ienai SPACE, based in Leganés, Madrid, Spain, develops ionic-liquid electric propulsion systems, such as the ATHENA™ electrospray thrusters, for small satellites and offers the 360™ SaaS tool for high-fidelity mission analysis. These tailored hardware modules and software services support orbital maneuvers, de-orbiting, and complex missions for 2U to 12U spacecraft, aiming to foster a sustainable new space economy. The company generates approximately $5.6 million in revenue and operates with fewer than 25 employees. ienai SPACE recently closed a 1 million euro seed funding round led by Inveready. They are also involved in a project with 22 other Spanish companies to launch a 30-satellite Earth observation constellation utilizing their propulsion technology. ienai SPACE was founded in 2019; founder names are not publicly available.
Key people at ienai SPACE.
Ienai SPACE is a Spanish aerospace startup founded in 2019 that develops customizable electric propulsion systems and mission analysis software for small satellites under 300kg, including CubeSats from 2U to 12U.[1][3][5] Their flagship ATHENA thruster, based on electrospray technology using ionic liquids, enables precise in-space mobility for tasks like orbit adjustments, constellation spacing, de-orbiting, and debris mitigation, paired with 360 SaaS for orbital optimization and ORBITAL for dynamics analysis.[2][4][5] Serving satellite manufacturers and operators, Ienai solves the "in-space mobility problem" by offering tailored, scalable propulsion that adapts to mission constraints rather than forcing platforms to adapt to off-the-shelf hardware, reducing propellant needs and volume.[1][3][5] With $5M in total funding, 15 employees, two European Space Agency (ESA) contracts worth 1-2M€, and first commercial deals, the company shows strong early momentum from its Madrid base.[1][2]
Ienai SPACE emerged from groundbreaking research by its founding team—doctoral graduates from the Electric Propulsion and Plasmas group at Universidad Carlos III de Madrid (UC3M)—who gained recognition at the 2017 35th International Electric Propulsion Conference for innovations in electrospray thrusters.[3] Founded in 2019 in Leganés, Madrid, the company spun out to commercialize this technology, evolving from academic R&D into a full end-to-end solution provider with hardware and software.[1][3] Early traction included selection for the SpaceFounders accelerator and Madrid ESA-BIC program, followed by ESA contracts and in-orbit demonstrations, growing the team to 15 while executing on commercial sales.[2][3]
Ienai SPACE rides the boom in small satellite constellations, nanosat swarms, and space debris regulations, where propulsion is essential for orbit maintenance, agility, and end-of-life disposal amid growing launches.[4][5] Timing aligns with Europe's push for space autonomy—reducing reliance on non-EU tech—as NATO emphasizes orbital domains and the EU funds strategic innovations; Ienai's ESA contracts and Madrid university ecosystem position it as a home-grown leader.[2][4] Market tailwinds include falling launch costs and demand for efficient, low-power propulsion in under-300kg sats, influencing the ecosystem by lowering barriers for new entrants in constellations and enabling sustainable operations.[1][5]
Ienai SPACE is poised to scale with in-orbit validations (e.g., first flight heritage) and commercial wins, targeting "maneuvering as-a-service" to dominate smallsat propulsion.[5] Rising constellation deployments, debris mitigation mandates, and EU autonomy initiatives will propel growth, potentially expanding to SmallSats and interplanetary hops.[4][5] As they hire (e.g., systems engineers) and close deals, Ienai could redefine in-space mobility, strengthening Europe's orbital sovereignty while unlocking missions once limited by propulsion constraints—echoing their mission to adapt tech to spacecraft, not vice versa.[3]
