German drone manufacturer Quantum Systems announced on Thursday it secured €180 million in a Series C extension funding round. The investment brings the company’s valuation to €3 billion, roughly $3.47 billion in US dollars.
The latest funding round was led by Balderton Capital. This marks the company’s second major raise in 2025, following a €160 million Series C in May.
The total amount raised this year now stands at €340 million. This represents the largest private capital raise in Europe’s dual-use technology sector for 2025.
Peter Thiel’s investment firm, Thiel Capital, remains a backer of the company. The Silicon Valley billionaire first invested through Thiel Capital during Quantum Systems’ Series B round in 2023.
Thiel, who founded Palantir Technologies, stated in 2022 that unmanned aircraft systems’ future lies in combining software and hardware. He described Quantum Systems as ahead of its competition.
The company was founded in 2015 by Florian Seibel, a German army officer who serves as co-CEO. Quantum Systems initially focused on aerial drones and AI-powered surveillance software.
The start-up first achieved unicorn status in May 2025 when its valuation reached €1 billion. The company has now tripled that valuation in just six months.
Expansion Plans and Acquisitions
Quantum Systems employs up to 1,000 people across multiple countries. The company has offices in Germany, Ukraine, the United States, Australia, Romania, the United Kingdom, and the Baltic states.
The company has already completed several acquisitions this year. These include AirRobot, Nordic Unmanned, and Spleenlab.
The new capital will fund additional strategic acquisitions. Quantum Systems plans to strengthen its multi-domain offerings across air, land, and maritime applications.
NATO Deployment and Military Use
The company’s drones serve both government and civilian purposes. Agricultural applications represent one civilian use case for the technology.
Quantum Systems’ platforms are currently deployed by NATO forces. The drones operate across Europe, the United States, Australia, and New Zealand.
The company’s fleet has been operating in Ukraine since the start of the full-scale invasion in 2022. This represents the most prominent deployment of Quantum Systems’ technology.
Seibel created a separate company called Stark to deliver attack drones. The company’s mission software, MOSAIC UXS, connects operations across multiple domains.
Rana Yared, General Partner at Balderton Capital, stated the investment supports European sovereignty in defense technology. Yared cited rising geopolitical instability and shifting security priorities as factors driving demand for European innovation.
The company’s €340 million raise in 2025 exceeds the combined funding of other European unmanned systems companies. Switzerland’s General Intuition raised €114 million, while Poland’s Orbotix secured €6.5 million for autonomous defense drones.
