About us

Space business is booming: the space market is growing rapidly, new market segments are opening, and disruptive changes are taking place. As consequence of this rapid growth, the number of satellites and spacecraft is strongly increasing – and each spacecraft needs a propulsion system to perform its specific task.

Here ISPTech’s propulsion technologies come into the play. Based on more than 10 years of research and development work at the German Aerospace Centre (DLR), ISPTech’s founders developed propulsion technologies that work with green (non-toxic) propellants. Our propulsion systems are characterized by a high efficiency, reliability and allow significant cost reductions.

By using these advanced propulsion technologies, ISPTech will satisfy the desperate demand for affordable, green and robust propulsion technologies and propel the whole Space ecosystem.

ISPTech’s relevance for the NewSpace market is backed by renowned deep tech investors (HTGF, Join Captial, Faber VC, First Momentum, Possible Ventures and others). We recently closed a €5.5M seed round.
