Europe’s defence technology boom is creating a new generation of unicorns and German drone maker Stark is rapidly emerging as one of its most closely watched players.
According to the Financial Times, Berlin-based Stark is in discussions with investors to raise at least €300 million in a new funding round that could value the company at approximately €2.5 billion. If completed, the deal would more than double the company’s valuation from earlier this year, when it reportedly crossed the €1 billion mark.
The reported financing comes just months after Stark reportedly secured fresh funding that lifted its valuation above €1 billion.
Stark was founded in 2024 by Florian Seibel, the founder of Quantum Systems, alongside Johannes Schaback. It develops strike drones and autonomous defence systems, operating in one of the fastest-growing segments of the industry.
Stark specialises in autonomous strike systems, particularly loitering munitions often referred to as kamikaze drones. Its flagship product, Virtus, is designed to autonomously identify and strike targets before self-destructing on impact, reflecting a broader shift toward low-cost autonomous warfare systems.
While the company faced technical setbacks during military trials in Germany and the UK last year, it has continued securing major contracts and expanding its product portfolio.
Its rise comes as European governments increasingly prioritise sovereign defence capabilities and domestic military technology following Russia’s full-scale invasion of Ukraine.
Defence has become one of venture capital’s fastest-growing sectors. The combination of autonomous weapons, drone defence systems, and growing military demand has made defence startups increasingly attractive to investors looking for long-term strategic opportunities.
Stark operates in a defence technology market that is attracting record levels of capital.
One of its biggest rivals is Munich-based Helsing, which is reportedly raising $1.2 billion at an $18 billion valuation. Helsing develops AI-powered military software, autonomous systems, and battlefield intelligence platforms, making it Europe’s most valuable defence technology startup in waiting.
Another major competitor is Quantum Systems, the German surveillance drone company backed by Peter Thiel and Airbus. The company secured €160 million in Series C funding in 2025 before extending the round with an additional €180 million, bringing total 2025 funding to €340 million and lifting its valuation above €3 billion.
Globally, Anduril remains one of the sector’s most formidable competitors. The US defence technology giant recently raised $5 billion in fresh funding at a $61 billion valuation, doubling its valuation in less than a year as investors aggressively backed autonomous defence systems, surveillance platforms, and military AI infrastructure.
Together, these companies are reshaping what has traditionally been a government-dominated defence procurement market.
Just a few years ago, defence technology was largely avoided by venture investors. Today, it has become one of the hottest sectors in global venture capital.
The war in Ukraine, rising geopolitical tensions, and growing demand for autonomous military systems have accelerated investment into defence startups across Europe and the United States.
For Stark, the reported €300 million fundraising would represent another major success in its remarkably fast rise from startup to unicorn.
The bigger challenge now is execution. As Europe races to build its own defence champions, companies such as Stark, Helsing, and Quantum Systems are competing not only for investor capital but also for military contracts, technological leadership, and a central role in shaping the future of autonomous warfare.
