Invested in 2025
The Mobility Layer For Space Economy
Founded by German Aerospace Center (DLR) veterans Dr. Lukas Werling and Dr. Felix Lauck, ISPTech is solving the propulsion bottleneck constraining every spacecraft in orbit. After leading non-toxic propulsion research at the German Aerospace Center, the duo witnessed how toxic hydrazine-based systems create operational complexity, regulatory risk, and cost barriers. Their dual-technology platform—HyNOx for rapid deployment and HIP_11 to replace toxic self-igniting propellants without spacecraft redesign—delivers green propulsion across every spacecraft class from CubeSats to large satellites, capsules or landers.
10+
As a DLR spin-off, ISPTech's propulsion solutions are built on more than a decade of research, offering cost-effective, robust and quickly available in-space propulsion for every spacecraft and every mission.
1N to 1kN
Complete thrust range serving every spacecraft class—from small CubeSats to large satellites, in-orbit service vehicles, and future mission architectures demanding kilonewton-level maneuver capability.
2026
First customer mission scheduled for launch, with CubeSat propulsion systems currently undergoing acceptance testing and customer deliveries planned throughout the year.
Qualified
First thrusters already space-qualified and customer systems undergoing acceptance testing—demonstrating flight-ready technology while competitors remain in development phases.
MISSION: Enable dynamic orbital operations through non-toxic, cost-effective propulsion systems that turn spacecraft mobility from operational constraint into strategic advantage—unlocking the in-space economy.
ISPTech eliminates the critical bottleneck where orbital mobility has become a hard constraint as satellite constellations densify and collision avoidance becomes mandatory. Traditional toxic hypergolic propellants face accelerating regulatory bans, while existing green alternatives sacrifice performance, availability, or operational simplicity.
By offering two complementary technologies—HyNOx for robust, continuously-firing operations with rapid availability, and HIP_11 as a true hypergolic replacement with hybrid electric/chemical capability—ISPTech addresses persistent challenges constraining satellite operators today. With secured customer contracts and ESA-backed development programs, the company is building the propulsion infrastructure for a fully functional in-space ecosystem—enabling reliable constellation management, active debris avoidance, on-orbit servicing, and the mission flexibility required as humanity expands into space.
