ISPTech Raises €5.5M Seed Round to Redefine How Spacecraft Manoeuvre in Orbit

Stuttgart, Germany – Marc. 17, 2026 – ISPTech, a German space technology company developing propulsion systems for agile in-orbit maneuvering, announced it has raised €5.5 million in seed funding to deploy its advanced, non-toxic propulsion solutions for operational space missions.

The round was led by Join Capital, with participation from High-Tech Gründerfonds (HTGF), Faber, First Momentum Ventures, Lightfield Equity, Final Frontier Liftoff, the German Aerospace Center (DLR), and Start-up BW Seed Fonds, among others. ISPTech said the funding will be used to expand manufacturing capabilities, test critical infrastructure and accelerate commercial deployment.

Today, there is a lack of rapid, agile and high thrust manoeuvring capabilities required for sustainable operations in all orbits and new mission needs across defence, servicing and refuelling. With mobility in orbit becoming a hard operational constraint, ISPTech is building propulsion systems which are now ready for spaceflight and accelerating commercial traction.
