Quantum Systems secures $1.2 billion at a valuation of $8 billion.

      Europe has welcomed a new heavyweight in defence technology. Quantum Systems, a German manufacturer of autonomous drones, has secured $1.2 billion in funding, more than doubling its valuation to approximately $8 billion. This funding round is among the largest ever witnessed by a European defence startup.

      On Thursday, the Bavarian company revealed its Series D funding round, co-led by Blackstone, Noteus, Airbus, and Advent. Other notable participants included Bond, Fidelity, Wellington Management, A.P. Moller Holding, as well as returning supporters Balderton and HV Capital. This funding boost elevates Quantum Systems' valuation to around €7 billion, a significant increase from about €3 billion late last year.

      Quantum Systems specializes in developing unmanned systems for aerial, terrestrial, and maritime applications. Its vertically-takeoff drones are utilized for reconnaissance and battlefield intelligence missions. The company integrates hardware, sensors, and counter-drone technology into one cohesive network through a software layer called MOSAIC UXS. Quantum Systems claims it is profitable, boasting double-digit margins, with revenue projected to have doubled to about €300 million by 2025.

      A Proven Track Record

      This is not merely theoretical. According to the company, Quantum’s drones have completed over 19,000 missions in Ukraine in 2025. The firm has established production facilities in Germany, Ukraine, the United States, Australia, Romania, the United Kingdom, and the Baltic states. Founded in 2015 by Florian Seibel, a former Bundeswehr helicopter pilot, the company aims to position itself as a “next-generation neo prime.”

      The new funding will support the continuation of its current initiatives. Quantum Systems intends to increase production capacity, strengthen its supply chain, expand into allied markets, and invest in artificial intelligence. Additionally, the company has plans to acquire other businesses. Seibel mentioned that it now possesses “more than $1.2 billion of dry powder to execute.”

      The Defence-Tech Surge

      This funding round comes amid a booming market. According to Dealroom, defence-tech startups have raised a record-breaking $17.4 billion so far this year, significantly surpassing the $11.2 billion raised throughout all of 2025. The majority of the largest investments have been funneled into U.S. companies, with Anduril securing $5 billion in May. In Europe, however, funding is concentrating on a select few companies.

      In the competitive landscape, rival Munich-based drone maker Helsing is expected to raise $1.2 billion with an $18 billion valuation, while Stark Defence raised €500 million in June.

      Blackstone’s involvement is significant. The firm, which typically manages over $1.3 trillion mostly in real estate, credit, and buyouts, seldom invests in drone startups. Senior Managing Director David Kaden highlighted that a “structural shift in the European defence market” has created new capital demands, indicating a shift in mainstream finance into a sector it once largely shunned.

      Prospects for Consolidation

      This funding round also revives discussions about potential consolidation. Seibel co-founded Stark as a separate entity in 2024, but existing weapon restrictions on certain Quantum investors prevented the development of strike drones. At a press conference, Seibel stated a willingness to consider a merger if it makes sense, though a Stark spokesperson indicated there were currently no plans for such a combination. Together, the valuations of both companies exceed $10 billion.

      Seibel is also exploring opportunities beyond defence, pointing to robotics and humanoid technology as potential new areas for Quantum. He maintained that “European solutions are essential.” For the time being, the focus remains on scaling the business. Although the company has conducted an IPO readiness review, it is not in a hurry to go public, with Europe now home to at least three drone unicorns vying for the same NATO contracts.

      A critical question remains whether the continent's budgets can support all of these ventures. Quantum’s drone swarm tests and its new financial resources indicate its intent to endure, contributing to a sector that has also benefitted cruise missile manufacturer Destinus.
