‍ISPTech is Redefining How Spacecraft Manoeuvre in Orbit

ISPTech, pioneering a new era of space mobility, led by Dr.-Ing. Lukas Werling, Dr.-Ing. Felix Lauck, and the team, has raised €5.5M million 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. Seed funding will support the expansion of manufacturing capabilities, testing of critical infrastructure, and the acceleration of commercial deployment.

The funding comes amid rising demand for easy-to-use, cost-efficient, and scalable propulsion solutions. The shift reflects a broader industry move toward safer, more flexible, and more affordable in-orbit mobility, a transition in which ISPTech aims to play a defining role.

Satellite constellations are growing denser and missions more complex, requiring precise orbital shifts and collision avoidance with zero tolerance for failure. However, rapid and high-thrust maneuvering capabilities in orbit remain limited. ISPTech is addressing this gap with spaceflight-ready propulsion systems, gaining traction among satellite manufacturers and mission operators, with additional applications in defense, servicing, and refueling.

At the same time, regulatory pressure is phasing out toxic propellants such as hydrazine, increasing costs and limiting flexibility for operators. Tightening restrictions are accelerating demand for safer propulsion alternatives that meet mission requirements without added operational risk.

Enabling Mobility for Every Spacecraft

As satellite deployments expand and missions demand greater precision, propulsion has become a critical operational constraint. ISPTech addresses this with HyNOx, an affordable and robust system designed for long firings, rapid availability, and real-world reliability across mission profiles.

The patented HIP_11 technology provides a safer alternative to toxic hypergolic propellants using a self-igniting hydrogen peroxide and ionic liquid combination. Serving as a drop-in replacement, it maintains reliability while enabling a unique multi-mode capability that supports both high-thrust and efficient electric maneuvers within a single system.

Together, HyNOx and HIP_11 support spacecraft ranging from CubeSats to large satellites, built on over a decade of propulsion research at the German Aerospace Center (DLR).

In-Orbit Missions Set for 2026

ISPTech is preparing two customer missions, including a small-satellite launch in 2026, while CubeSat propulsion units undergo final acceptance testing ahead of deliveries this year. Early contracts, including a partnership with Atmos Space Cargo, reflect growing market confidence.

With development supported by the European Space Agency, ISPTech is advancing multi-mode propulsion systems designed to transform in-orbit mobility into a foundational layer of the future space economy.
