HyImpulse Technologies, a German developer of small launch vehicles, said this week it had extended its Series A funding round by more than €50 million, bringing its total equity raised in the round to over €65 million and its lifetime funding to more than €125 million. The extension was co-led by Berlin venture firm JOIN Capital and Israeli aerospace investor Ace Capital Partners, neither of which took part in the company's initial Series A close.
Existing backers North Ventures, BW-Capital, Bayern Kapital, Campus Founders Ventures and the German Aerospace Center also participated, according to the company's announcement, reported by Tech Funding News. HyImpulse first disclosed a €15 million Series A round in October 2025.
Two launches on the horizon
The Neuenstadt-based company builds rockets powered by hybrid propulsion, which pairs a solid fuel with a liquid or gaseous oxidizer — a design its founders say is safer to handle and cheaper to produce than conventional liquid-fueled engines. HyImpulse is preparing for the second flight of its suborbital SR75 rocket alongside the inaugural launch attempt of SL1, a larger vehicle intended to reach orbit, according to EU-Startups.
HyImpulse said its order book now exceeds €350 million, though the company has not detailed how much of that figure reflects binding contracts versus non-binding letters of intent — a distinction that matters in an industry where launch manifests routinely slip by months or years.
The round arrives amid a broader push by European governments and investors to build homegrown launch capacity independent of U.S. providers, a priority that has taken on new urgency as access to some non-European launch services has grown more politically fraught. Germany alone now hosts several small-launcher startups competing for a still-nascent market for dedicated small-satellite launches, and HyImpulse's extension — its second capital infusion in under a year — suggests investors remain willing to fund the sector even before any of the German entrants has reached orbit.
Investors in the round include the German Aerospace Center, a state research agency that has increasingly co-invested alongside private venture funds in domestic launch companies as Berlin looks to reduce reliance on foreign rocket providers for both commercial and government payloads. HyImpulse has not disclosed a target date for SL1's first orbital attempt, but executives have said the SR75 suborbital flight is intended to validate propulsion and recovery systems ahead of that larger launch.
