ISPTech secures €5.5M seed to improve in-orbit mobility

**ISPTech Secures €5.5 Million Seed Round to Pioneer Next-Generation In-Orbit Propulsion** German space technology firm ISPTech has successfully closed a €5.5 million seed funding round, signaling significant investor confidence in its innovative, non-toxic propulsion systems designed for advanced in-orbit maneuvering. This substantial investment, led by Join Capital and supported by a consortium of venture capital firms and established entities including the German Aerospace Center (DLR), will fuel the company's efforts to deploy its technologies for operational space missions. The funding underscores a growing recognition of the critical need for agile and safe propulsion solutions within the rapidly evolving satellite industry. The increasing density of satellite constellations and the growing complexity of space missions necessitate spacecraft capable of precise orbital changes and collision avoidance with minimal error margins. Traditional propulsion systems often fall short in providing the necessary agility, responsiveness, and thrust for these demanding requirements. Simultaneously, escalating regulatory pressure is driving the phase-out of conventional, highly toxic propellants like hydrazine, compelling satellite manufacturers to seek safer, more sustainable alternatives. ISPTech's technology directly addresses these converging challenges. ISPTech's innovative propulsion systems, including the HyNOx and HIP_11, are being developed as non-toxic alternatives for agile maneuvering across various spacecraft classes. The company is actively engaged in commercial partnerships with satellite manufacturers and mission operators, with potential applications extending to defense, in-orbit servicing, and refueling. With two customer missions in preparation and a small-satellite mission utilizing ISPTech propulsion slated for a 2026 launch, the company is demonstrating tangible progress and early customer traction. This advancement positions ISPTech as a key player in fostering a more capable and scalable European space ecosystem, contributing to enhanced digital sovereignty in orbit.
