Quantum Systems secured $1.2 billion in a Series D funding round, increasing its valuation to approximately $8 billion as of early July 2026 [1, 2, 3]. The round was co-led by Blackstone, Noteus, Airbus, and Advent, reflecting strong investor confidence in the defense technology firm [1, 3].
The company designs and manufactures unmanned aerial, land, and sea vehicles used primarily for surveillance and defense missions [1, 3]. In 2025, Quantum Systems completed over 19,000 drone missions supporting Ukraine following Russia’s invasion, demonstrating the operational relevance of its technology in active conflict zones [3]. Its revenue doubled to about €300 million in 2025 and the company expects similar growth in 2026 [1].
Quantum Systems is expanding its commercial footprint internationally, targeting new markets including Romania, the UK, the Middle East, and Asia Pacific, while maintaining existing operations in Germany, Ukraine, the United States, Australia, and the Baltics [1, 3]. Co-CEO Florian Seibel said, "Defense will be defined by autonomous systems that can operate together across domains in real time. With Quantum Systems, we are building a next generation neo prime that has the potential to disrupt defense as we know it today" [3].
The new funds will be used to expand production capacity, strengthen supply chain resilience, scale delivery to allied markets, and invest in software and artificial intelligence capabilities [1, 3]. Despite minority investment by Peter Thiel, the company has not faced government scrutiny related to his involvement. Jonas Jarosch, Quantum Systems’ CFO, noted, "Peter Thiel is one of, I don't know, 35 investors in our company. Historically, Peter Thiel was the key investor who led the defence tech growth that occurred when European and other investors were not willing" [1].
Quantum Systems has undergone an IPO readiness assessment but does not plan an immediate public offering [1]. Its fundraising comes amid record investments in defense tech, with companies in the US and Europe raising $17.4 billion so far in 2026 [3]. Other European defense drone startups such as Helsing and Stark Defence are also securing large funding rounds [1, 3].
Separately, the Dutch Defence Ministry announced a multi-year investment in Delft-based Intelic to develop drone software that enables interoperability across unmanned systems from different manufacturers. Dutch junior defence minister Derk Boswijk explained, "Ukraine teaches us that not only the hardware, but also the software is of great importance. Making different drone systems work together makes the fight easier" [4]. Intelic CEO Maurits Korthals Altes added, "Europe now has more than 700 drone manufacturers, and that number continues to grow. For defence organisations, the challenge is no longer access to technology, but ensuring those technologies can operate together" [4].
Blackstone’s David Kaden commented, "A structural shift in the European defense market has created significant demand for capital to support the sector's development and the adoption of advanced technologies" [3].
Quantum Systems announced its Series D funding and expansion plans on July 2 and 3, 2026, marking a major step in its growth trajectory [1, 3].
