HyImpulse, a German company that builds hybrid-propellant rockets, raised more than €50m (about $57.9m) in an extension of its Series A round, it was announced on 2 September 2026. The round was co-led by JOIN Capital and Ace Capital Partners.
New investors North Ventures, BW-Capital, Bayern Kapital and the German Aerospace Center (DLR) joined, and existing shareholder Campus Founders Ventures also took part, according to tech.eu. No valuation was disclosed.
The money will go towards developing and commercialising HyImpulse's launch services, including preparations for the next mission of its SR75 suborbital rocket and the maiden flight of its SL1 orbital launcher. The company also plans to expand production capacity and commercial operations in Europe and other markets.
“Europe needs sovereign, responsive and economically sustainable launch capabilities. Our proprietary hybrid propulsion technology and suborbital and orbital services position us to meet growing demand across commercial, institutional and defence markets.”Christian Schmierer, Co-Founder and CEO, HyImpulse
What HyImpulse does
HyImpulse develops launch vehicles powered by a hybrid propulsion system that burns paraffin-based fuel with liquid oxygen. The company says the design needs fewer components and is less complex than conventional liquid-fuel engines.
Its SR75 suborbital rocket is aimed at research, testing and defence work. After a first flight campaign at the Koonibba Test Range in South Australia in 2024, the company is preparing a second SR75 launch from SaxaVord Spaceport in Scotland by the end of 2026. It is also developing the SL1, an orbital launcher for dedicated and responsive satellite launches, and is targeting in-space mobility, hypersonic testing and threat simulation.
The company was founded in 2018 as a spin-off of DLR, according to Vestbee, and has more than 100 employees across Germany and the UK. Startbase reported that staff work in Neuenstadt, Ottobrunn and Glasgow.
A state investor joins
The Baden-Württemberg state government highlighted the participation of BW-Capital, the state's investment company, in a press release. Economics minister Nicole Hoffmeister-Kraut, who chairs BW-Capital's supervisory board, said the new capital and an order book of more than €350m (about $405m) showed that high-tech from the state was in demand internationally.
Finance minister Danyal Bayaz, the board's deputy chair, said it was an important signal that a state company was taking part in the growth round, and that public and private capital were working together to fund innovation in Baden-Württemberg.
The order book covers satellite launches, in-space mobility, suborbital research and defence, according to Vestbee.
The funding so far
In October 2025, HyImpulse raised €15m (about $17.5m) in equity as part of its Series A round, led by Campus Founders Ventures, and secured a further €30m in other financing, Satellite Today reported at the time.
With the extension, HyImpulse said it has raised more than €125m in total from equity and public funding. The company has not broken down how much of that total was equity.
Co-founder and chief executive Christian Schmierer said demand for launch capacity was growing across commercial, institutional and defence markets as Europe works towards independent access to space.
