Quantum Systems raises $1.2bn and doubles valuation to $8bn as defense funding surges
German drone manufacturer Quantum Systems has secured one of the largest funding rounds in European defense history, reaching an $8 billion valuation.
German technology company Quantum Systems, a leader in autonomous drone development, has announced the closure of a $1.2 billion Series D funding round. This milestone has pushed the company’s valuation to $8 billion, more than double its valuation from late last year, which sat at approximately $3 billion. The round marks one of the most significant financial milestones ever recorded for a European defense startup.
The investment was co-led by major global players including Blackstone, Airbus, Noteus, and Advent. Other prominent participants included Bond, Fidelity, Wellington Management, A.P. Moller Holding, along with existing backers Balderton and HV Capital. Founder Florian Seibel stated the company now has over $1.2 billion in 'dry powder' to accelerate its strategy, which includes expanding manufacturing capacity, hardening supply chains, and investing heavily in AI technologies.
Quantum Systems has proven its technology in real-world scenarios, noting that its drones successfully completed over 19,000 missions in Ukraine in 2025. The company’s technical core is powered by the MOSAIC UXS software layer, which integrates hardware, sensors, and counter-drone systems into a cohesive network. To meet surging demand, the firm has established production facilities across Germany, Ukraine, the United States, Australia, Romania, the UK, and the Baltics.
From a financial perspective, the company has seen exceptional growth, with revenue doubling to approximately €300 million in 2025 while maintaining double-digit profit margins. The massive influx of capital reflects a broader shift in the global investment landscape; with defense startups raising over $17.4 billion this year, mainstream finance is moving into a sector previously ignored. Even investment giants like Blackstone, which manages over $1.3 trillion in assets, are recognizing the structural shifts driving demand for defense innovation.
Looking forward, market consolidation is a key topic for the company. With Florian Seibel having previously co-founded Stark Defence, there is ongoing discussion about a potential merger that could create a powerhouse with a combined valuation exceeding $10 billion. Despite rumors of potential public market activity, the company says it has performed an IPO readiness review but is in no rush to list, choosing instead to focus on its role as a next-generation European defense prime.
