The European drone manufacturer Quantum Systems has raised $1.2 billion in a Series D funding round. These funds are intended to expand the company's autonomous defense technology platform. This investment values the German company at approximately $8 billion.
Round Participants and Company History
The financing was co-led by Blackstone, Noteus, Airbus, and Advent, and supported by BOND, Fidelity Management & Research Company, Wellington Management, A.P. Moller Holding, Elephant Lake Ventures, Balderton, and HV Capital. The company was founded in Munich and develops autonomous drones for defense, security, and commercial use. Quantum Systems already holds orders from NATO forces and commercial clients in the US, Ukraine, and Australia.
This round more than doubled the company's previous valuation, which stood at about $3.5 billion less than a year ago. Florian Zeibel, co-founder and co-CEO, told reporters that the company is profitable, and the available over $1.2 billion will allow it to scale up.
Application of New Capital and Technology
The majority of the raised capital will be directed towards strengthening the MOSAIC UXS software platform. This system integrates drones, sensors, anti-drone capabilities, and drone ports into a single operational network. Integrated software is becoming increasingly important as defense structures implement autonomous systems across various fields. The company's systems operate in air, land, and sea, utilizing artificial intelligence and real-time data analysis.
The company plans to use the funds to increase production capacity, stimulate global sales, and continue working on next-generation AI-based autonomous systems. Co-CEO Sven Kruck noted this direction.
Strategic Development and Market
Quantum Systems was founded in 2015 by Florian Zeibel, who previously served as a pilot in the German Air Force (Luftwaffe). Initially, the business focused on agricultural surveying before transitioning to developing solutions for defense and intelligence. The investment from Blackstone is considered significant because the fund rarely supports European drone manufacturers. The managing firm controls assets worth $1.3 trillion, reflecting growing institutional confidence in Europe's defense technology sector.
David Caden explained Blackstone's investment as a reaction to structural changes in the European defense market, stating that the growing demand for advanced technologies requires long-term capital to support industry expansion and security infrastructure. Furthermore, Airbus strengthened its ties with Quantum Systems through investment and strategic cooperation. This partnership will combine expertise in software, artificial intelligence, and defense systems to enhance the operational capabilities of both companies.
Quantum Systems has also expanded through acquisitions, previously integrating AirRobot, Nordic Unmanned, and Spleenlab to broaden its technology portfolio and strengthen its offering of autonomous systems.
Overall Trend in European Defense
The latest investment reflects a general momentum in Europe's defense technology industry. According to Dealroom and the NATO Innovation Fund, defense, security, and sustainability startups in Europe attracted a record $8.7 billion in 2025. Quantum Systems joins the growing group of European drone 'unicorns' competing for NATO contracts. Competitor in the defense technology sector, Helsing, also raised $1.2 billion earlier this year, achieving a significantly higher valuation of $18 billion. Other defense technology firms continue to attract large sums of funding as governments increase spending on autonomous systems. Quantum Systems combines hardware, artificial intelligence, and mission software into one integrated platform, which, according to the company, positions it well for both military and civilian markets.
