Quantum Systems Raises $1.2BN at $8BN Valuation in Europe DefenceTech Surge

A Rapid Ascent in Valuation

According to Tech.eu, Quantum Systems last raised money in November 2025 at a valuation exceeding €3 billion, meaning the new round more than doubles that figure. The Series D was co-led by US investment giant Blackstone, European growth investor Noteus, aircraft maker Airbus and private equity firm Advent.

A long list of institutional backers also joined, including Bond, Fidelity, Wellington Management, A.P. Moller Holding and Elephant Lake Ventures, alongside existing shareholders Balderton and HV Capital, as reported by EU-Startups.

Founded in 2015, Quantum Systems develops unmanned aerial and land systems that blend hardware, software and artificial intelligence. Its MOSAIC UXS software platform links drones, sensors, counter-drone systems and partner technologies into a single interoperable network. Co-CEO Florian Seibel said the company is building what he called a "next-generation neo prime" with the potential to reshape the defence sector, adding that Quantum Systems is already profitable and now holds more than $1.2 billion in "dry powder."

Battlefield-Proven and Expanding

The company's technology is deployed by NATO forces across Europe and the United States, as well as in Australia and New Zealand. Its most prominent deployment has been in Ukraine, where its fleet has operated since Russia's full-scale invasion in 2022. EU-Startups reported that Quantum Systems' systems carried out more than 19,000 missions in Ukraine during 2025.

Production now spans Germany, Ukraine, the United States, Australia, Romania, the United Kingdom and the Baltics. Co-CEO Sven Kruck said the fresh capital would allow the firm to scale manufacturing, expand internationally and deliver AI-powered autonomous systems across air, land and sea domains. CFO Jonas Jarosch pointed to triple-digit growth and double-digit profitability as evidence of the company's financial discipline.

Airbus Deepens Ties, Merger Talk Circles

Alongside the funding, Airbus Defence and Space agreed to strengthen its strategic collaboration with Quantum Systems. Airbus Defence and Space CEO Michael Schoellhorn said modern combat is decided by decision speed and framed the partnership as combining architectural, software and AI capabilities to accelerate the so-called sensor-to-shooter chain.

In an interview with the Financial Times, Seibel signaled openness to a possible merger with Stark, a German weaponised drone maker he also co-founded, saying he was never happy that Stark was built outside Quantum. He stressed, however, that there is currently "no roadmap" for such a tie-up. Sifted separately reported the company is also eyeing a move into humanoid systems.

The round follows a wave of European drone and autonomy financings throughout 2026, with Quantum Systems' latest raise dwarfing the adjacent deals tracked across the sector.

Ottawa-based Dominion Dynamics raised what is believed to be Canada's largest-ever defence tech Series A, drawing global investors to its Arctic surveillance push.
