€50m+ · Series A · Space · Neuenstadt am Kocher, Germany
HyImpulse, a German launch-services company developing suborbital and orbital rockets, has raised a €50m+ Series A extension co-led by JOIN Capital and Ace Capital Partners. New investors include North Ventures, BW-Capital, Bayern Kapital and the German Aerospace Center (DLR), while Campus Founders Ventures returned. The company said the equity will accelerate development and commercialisation of its SR75 and SL1 launch platforms, expand production and scale commercial operations across Europe and beyond, including a planned second SR75 launch and the maiden flight of SL1. The company announcement sets out the round and planned use of funds.
This is an extension to HyImpulse’s Series A, not its cumulative funding total. The company says it has now secured more than €125m across equity and public funding.
From propulsion proof to a launch service
HyImpulse is building around a hybrid propulsion architecture that combines solid paraffin fuel with liquid oxygen. The company says this keeps the fuel inert during handling while reducing system complexity, and its technology page describes motors that can be shut down and restarted. That propulsion system spans two different customer propositions: SR75 suborbital missions can carry up to 250kg to around 200km, while SL1 is designed initially for up to 600kg to low-Earth orbit.
The important evidence is that HyImpulse has moved beyond ground testing, but not yet completed the orbital step. Its SR75 flew successfully from Koonibba, Australia, in May 2024, validating the 75kN motor in flight. The new capital is intended to fund the less glamorous but commercially decisive work between a demonstration and a service: building vehicles, preparing launch operations and creating enough production capacity to fly for customers repeatedly.
Booked demand still has to become launch cadence
HyImpulse reports an order book above €350m, a figure also cited by BW-Capital’s official announcement. JOIN Capital’s stated investment case is that the hybrid architecture uses roughly half the parts of a conventional rocket and could materially lower the capital and cost required to reach orbit. Those are investor and company claims, but they identify the round’s commercial wager: a simpler propulsion stack can matter only if HyImpulse converts it into reliable flight frequency and acceptable launch economics.
The next milestones therefore carry more weight than the size of the order book alone. A second SR75 mission would test whether the company can repeat its flight performance in a commercial setting; SL1’s maiden flight would determine whether the same propulsion approach scales into orbital delivery. The financing gives HyImpulse more runway to cross both thresholds, while leaving launch execution, licensing and production ramp-up as the central dependencies.
