Berlin's Stark raises €300M at €2.5B valuation for kamikaze drones

At a glance:

• Berlin's Stark is raising €300 million at a €2.5 billion valuation, doubling its worth in just months
• The 18-month-old startup builds autonomous strike systems, including kamikaze drones like its Virtus product
• European defense tech is booming, with competitors like Helsing, Quantum Systems, and Anduril also raising massive funding rounds

The Berlin Defense Startup's Meteoric Rise

Berlin-based drone startup Stark is in discussions to raise at least €300 million at a valuation of approximately €2.5 billion, according to the Financial Times. If completed, this deal would more than double the company's valuation from earlier this year, when it crossed the €1 billion mark to become a unicorn. Remarkably, the company is only 18 months old, making it one of the fastest-growing defense startups in European history.

Stark was co-founded by Florian Seibel, who previously founded rival German drone maker Quantum Systems, and Johannes Schaback. The company has quickly established itself in the competitive defense technology sector, attracting significant investor interest despite facing technical challenges during military trials in Germany and the UK last year. The company's ability to secure major contracts and expand its product portfolio despite these setbacks demonstrates the strong market demand for autonomous defense systems in Europe.

Kamikaze Drones and the Future of Warfare

Stark specializes in autonomous strike systems, particularly loitering munitions—military drones designed to hover over target areas, identify threats, and destroy them by self-destructing on impact. The company's flagship product, Virtus, exemplifies this capability by autonomously identifying and striking targets before detonating. These systems are often referred to as kamikaze drones, reflecting their one-way mission profile and the broader shift in modern warfare toward low-cost autonomous weapons that can be produced and deployed at scale.

The development of such technology represents a significant evolution in military strategy, moving from traditional, expensive weapon systems to more affordable, mass-producible alternatives. Loitering munitions like Virtus offer tactical advantages by providing persistent surveillance over battlefields while maintaining the ability to strike targets with precision. This approach has gained particular relevance in the context of modern conflicts, where the ability to rapidly deploy and replace equipment is crucial for maintaining operational effectiveness.

European Defense Tech Boom

Stark's rapid valuation growth is part of a larger trend in European defense technology, which is attracting capital at record rates. Munich-based Helsing is raising $1.2 billion at an $18 billion valuation, while Quantum Systems, Seibel's first company, raised €340 million in 2025 and is now valued above €3 billion. Notably, Peter Thiel is an investor in both Quantum Systems and, according to the Financial Times, in Stark's upcoming round.

Globally, the defense tech sector is experiencing unprecedented growth. US-based Anduril raised $5 billion at a $61 billion valuation, doubling in less than a year. Netherlands-based Destinus is raising €200 million ahead of an Amsterdam IPO at a €5 billion valuation, with a Rheinmetall joint venture already producing 2,000 cruise missiles annually. Defense tech venture capital reached $49.1 billion globally in 2025, nearly double the amount raised in the prior year, signaling strong investor confidence in this sector.

Stark's Competitive Landscape

The competitive landscape in European defense drones is intensifying, with Stark, Helsing, and Quantum Systems all operating from Germany and competing for the same military contracts, engineering talent, and investor capital. The fact that Stark's founder previously built Quantum Systems adds a personal dimension to this rivalry, creating a dynamic where innovation and execution are being closely watched by investors and military customers alike.

European governments are actively driving demand for these technologies through increased defense spending initiatives. The EU's ReArm Europe plan aims to mobilize up to €800 billion in defense spending over four years. Germany's special defense fund, established after Russia's invasion of Ukraine, has accelerated procurement of autonomous systems. Additionally, the European Defence Industry Programme, adopted in March 2026 with a €1.47 billion budget, dedicates specific funding for counter-drone and autonomous strike capabilities, creating a favorable environment for companies like Stark to grow.

The Path to Industrial Production

A critical challenge facing defense tech startups like Stark is the transition from venture-backed prototyping to industrial-scale production. While the company has secured contracts and developed its product line, it has not yet demonstrated manufacturing at the volumes required for large-scale military procurement. This represents a significant hurdle for the company as it seeks to establish itself as a major supplier in the defense industry.

Competitors are at different stages of this production journey. Helsing has invested heavily in developing advanced AI capabilities that support autonomous systems, while Quantum Systems has more operational maturity from years in the market. Destinus has already achieved scale, with its joint venture producing 2,000 cruise missiles annually. For Stark, the €300 million raise is intended to provide the capital needed to build production capacity before competitors dominate the market. The company's ability to execute this transition will be crucial to its long-term success and ability to fulfill the expectations set by its high valuation.

The Investment Bet on Autonomous Weapons

For investors, the underlying assumption is that autonomous strike drones will become a commodity deployed in the tens of thousands across military operations globally. This bet reflects a broader belief that autonomous systems will fundamentally change warfare by providing cost-effective, scalable alternatives to traditional weapon platforms. The rapid valuation growth of companies like Stark, Helsing, and Anduril suggests that investors see this transition as inevitable and are positioning themselves to capture the economic opportunities it presents.

Eighteen months from founding to a €2.5 billion valuation represents remarkable speed in any industry, let alone the traditionally conservative defense sector. However, this rapid ascent also raises questions about whether execution can match the ambitious fundraising. Whether Stark becomes a European defense champion or serves as a cautionary tale about how venture capital can inflate companies before they've demonstrated scalable production capabilities remains to be seen. The company's next phase of development will be closely watched by investors, military customers, and competitors alike as it seeks to translate its technological promise into industrial reality.
