Europe’s Defense Startups Draw Record Venture Capital in 2025, Signaling a Strategic Shift

Europe’s defense technology sector is experiencing a surge unlike anything in its history. Venture capital investment in defense startups has reached a record-breaking $1.5 billion in 2025 — transforming a once-niche market into one of the continent’s most dynamic innovation arenas.

According to multiple venture data sources, defense technology now accounts for 6.2 percent of total European venture funding, up from less than 1 percent in 2020. Analysts say the sharp rise reflects Europe’s accelerated push for technological sovereignty and strategic resilience in an increasingly uncertain world.

“For years, defense innovation in Europe relied on government grants and legacy contractors. Now private capital is pouring in, fueling startups that move faster and think bigger,” said one investor specializing in dual-use technologies.

AI, Robotics, and Autonomy Drive the Boom

The new investment wave is anchored in AI-driven systems, autonomous platforms, and robotics — technologies that underpin the next generation of military intelligence, surveillance, and logistics.
Startups in quantum computing, cybersecurity, and AI microchips are also capturing investor attention, as governments recognize the importance of sovereign computing and secure supply chains.

While Europe leads globally in quantum technology venture funding, it still trails the United States in space technology and AI semiconductor production — gaps policymakers aim to close through coordinated EU initiatives and cross-border funds.

Landmark Funding Rounds Reshape the Landscape

The sector’s momentum is illustrated by several high-profile deals:

• Helsing, the Munich-based AI defense software leader, raised €600 million in June 2025, the largest-ever European defense tech round. The company develops advanced battlefield intelligence and autonomous mission systems, positioning itself as a cornerstone of Europe’s digital defense future.
• Quantum Systems, a drone and autonomy specialist, secured €160 million to expand production of high-end unmanned aircraft.
• Tekever, a pioneer in maritime surveillance and space integration, continues to attract growth capital across Europe.
• UDS (Unmanned Defense Systems) raised €3.2 million to scale swarm reconnaissance drones used in frontline intelligence.

The number of unique investors participating in defense tech has tripled since 2019, with projections showing another 300 percent increase by year-end as new funds, including Keen Venture Partners (backed by the European Investment Fund), allocate dedicated defense capital.

Strategic Autonomy Meets Private Capital

Europe’s pivot toward strategic autonomy is reshaping the perception of defense among investors. Once cautious about ethical or regulatory complexities, venture firms now view defense innovation as essential infrastructure, comparable to energy or healthcare.

Still, challenges remain. Late-stage funding for large-scale manufacturing lags U.S. counterparts, and export control-scan slow commercial deployment. But with geopolitical shocks underscoring the need for self-reliance, analysts expect Europe’s defense startup ecosystem to double in size within three years.

Regional Opportunities

For Southeast Europe and the Balkan region, the trend offers a timely opportunity. Emerging dual-use manufacturers and AI research hubs can tap into the growing investor appetite, provided they align with EU compliance standards and international procurement frameworks.
