Quantum Systems Raises $1.2Bn Series D to Accelerate Growth and Scale Software-Defined Autonomous Systems Across Air, Land and Sea

Quantum Systems, building the unmanned future, led by Florian Seibel, Sven Kruck, and Dave Sharpin, has announced the signing of its $1.2 billion Series D financing round, valuing the company at  ~ $8 billion on a post-money basis. The round was co-led by Blackstone, Noteus, Airbus and Advent, and supported by a high-calibre syndicate of crossover and long-term institutional investors including BOND, Fidelity Management & Research Company, Wellington Management, A.P. Moller Holding, and Elephant Lake Ventures, as well as existing shareholders such as Balderton and HV Capital.

Financing and Strategic Expansion.

The Series D financing more than doubled Quantum Systems’ valuation, reflecting strong revenue growth, profitability, and its positioning as a category leader in multi-domain uncrewed systems.

The new capital will support the company’s transition from standalone platforms to an interoperable family of systems connected through MOSAIC UXS, its software ecosystem for coordinating uncrewed operations.

Alongside the financing, Quantum Systems and Airbus Defence and Space expanded their strategic collaboration to accelerate the development of next-generation sovereign European defence capabilities.

Leadership Perspective.

Florian Seibel, co-CEO and co-founder of Quantum Systems, said the future of defence will be defined by autonomous systems operating together across domains in real time. He described the company as building a next-generation defence technology leader, emphasizing its profitability, global deployments, and strong capital position following the latest financing round.

Sven Kruck, co-CEO, said the company has rapidly become a trusted defence technology partner. He noted that the new funding will enable Quantum Systems to scale production, expand internationally, and accelerate the deployment of AI-powered autonomous systems across air, land, sea, and adjacent domains.

Proceeds and Strategic Expansion.

Proceeds from the financing will be used to expand production capacity, strengthen supply chain resilience, scale delivery across allied markets, and continue investing in software and AI capabilities.

Quantum Systems CFO Jonas Jarosch highlighted the company’s financial trajectory, describing it as a new benchmark for the defence sector, with strong growth, profitability, and disciplined execution. He said the financing enables the next phase of industrialisation of its multi-domain platform and continued investment in core technology infrastructure.

The company also reported significant operational scale, including more than 19,000 missions executed in Ukraine in 2025, alongside an expanded production footprint spanning Germany, Ukraine, the United States, Australia, Romania, the United Kingdom, and the Baltics.

Airbus Defence and Space CEO Michael Schoellhorn emphasized the importance of autonomous systems in accelerating decision-making and improving integration across crewed and uncrewed platforms. He noted the collaboration aims to strengthen sensor-to-shooter capabilities through deeper software, AI, and systems integration.

Blackstone’s David Kaden pointed to rising demand for capital in the European defence sector, while Noteus and Advent partners highlighted Quantum Systems’ role in scaling sovereign unmanned capabilities through software, AI, and industrial execution.
