The US defense tech ecosystem is thriving, fueled by rising defense budgets, evolving procurement strategies, and venture-backed startups disrupting entrenched incumbents. Agencies like DIU (Defense Innovation Unit), AFWERX, and In-Q-Tel bridge the gap between the Pentagon and private-sector innovation, ensuring that non-traditional players have access to contracts and funding.
🔹 Leading US Defense Tech Startups
Here are a few notable startups that you’ve likely heard of, each making significant strides in the defense tech sector.
- Anduril Industries: Specializes in autonomous defense solutions, redefining military AI. In June 2023, Anduril raised a $450 million Series D funding round at a post-money valuation of $4.6 billion. The round was led by Elad Gil, with participation from investors such as Andreessen Horowitz, 8VC, Founders Fund, General Catalyst, Lux Capital, Valor Equity Partners, and D1 Capital Partners.
- Shield AI: Focuses on AI-powered autonomous aviation. In January 2025, Shield AI secured approximately $200 million in a new funding round, increasing its valuation to $5 billion. Notable investors in this round include Palantir, Airbus, L3 Harris, Andreessen Horowitz, Point72, and Riot Ventures.
- Palantir Technologies: Provides big data analytics for intelligence and military operations. Palantir has raised more than $3 billion in funding, with investors including In-Q-Tel, which has connections to the CIA.
- Rune: Develops AI-powered military logistics solutions. In February 2025, Rune raised $6.2 million in a seed funding round led by Andreessen Horowitz, with participation from Point72 Ventures, XYZ Venture Capital, and individual investors, including executives from Anduril.
🚧 Challenges & Emerging Solutions
Despite its advantages, the US defense procurement system remains a bureaucratic maze that startups struggle to navigate. However, increasing competition with China has pushed the government to adopt more agile funding mechanisms, such as Other Transaction Authority (OTA) agreements and accelerated procurement cycles, enabling startups to scale faster.
🇪🇺 Europe: A Shifting Landscape with Room to Grow
Europe’s defense startup ecosystem is gaining traction, but it still faces structural challenges. The industry has long been dominated by large primes like Airbus, Thales, BAE Systems, and Leonardo, making it difficult for startups to break through. Unlike the US, where venture-backed firms routinely secure contracts, European startups face fragmented national procurement systems and risk-averse institutional investors.
🔹 Leading European Defense Tech Startups
Here are some standout European defense tech startups that are rapidly gaining traction and reshaping the industry.
- Helsing (Germany): An AI-driven defense software company that has raised approximately €761.5 million over multiple funding rounds. Investors include Prima Materia, General Catalyst, Accel, Lightspeed Venture Partners, and Saab.
- Preligens (France): Specializes in intelligence and surveillance analytics. The company secured $23.7 million in a Series A funding round held on November 19, 2020, with investors such as Bpifrance, 360 Capital Partners, and ACE Management.
- ARX Robotics (Germany): Develops autonomous military-grade robotics and has raised €9 million in a seed funding round co-led by the NATO Innovation Fund, Project A, and Discovery Ventures. This round is noted as the largest seed funding for a European DefenseTech company.
- VRAI (Ireland): Focuses on AI-powered simulation technology for defense and aerospace. The company raised €5 million in a Series A funding round led by Beringea, with participation from Enterprise Ireland, Northstar Ventures, and Irish family offices.
🚀 The Changing Investment Landscape
The war in Ukraine has accelerated defense spending and exposed weaknesses in legacy procurement models. Initiatives like the European Defence Fund (EDF), NATO’s DIANA program, and national-level funding programs are now creating more opportunities for startups.
Furthermore, VC interest in European defense tech is rising, with firms like Lakestar, OTB Ventures, and Alpine Space Ventures making their first moves into the sector. However, Europe still lacks the equivalent of the US’s DIU or AFWERX, leaving startups reliant on slower, less startup-friendly procurement processes.
📈 Rising Defense Budgets: Fueling the Future
According to Goldman Sachs Research (Feb 27, 2025), European defense spending is set to increase by €80 billion ($84 billion) by 2027 — equivalent to 0.5% of GDP.
- Germany plans to exempt defense spending from budget constraints and allocate €500 billion to infrastructure, potentially accelerating Eurozone growth.
- EU leaders are considering issuing defense-specific debt, marking a major shift in European defense financing.
- European defense manufacturers are poised to outpace US competitors, particularly as procurement shifts back to domestic suppliers.
Historically, Europe sourced 90% of defense equipment domestically in France, 80% in Germany, and 70% in Italy (2005–2022). However, post-Ukraine, Europe initially turned to non-EU suppliers, but now, domestic manufacturing is rebounding.
🤝 Bridging the Gap: Transatlantic Collaboration
Despite structural differences, the US and Europe are strengthening transatlantic cooperation in defense innovation. Initiatives like AUKUS, NATO’s DIANA program, and joint US-EU funding programs aim to align startups, investors, and governments on both sides of the Atlantic.
💡 The Future of Dual-Use Technologies
For startups, the opportunity lies in developing dual-use technologies — solutions that can serve both defense and commercial markets.
For investors, the challenge is balancing government contracts, regulatory hurdles, and long-term startup scalability.
Venture-backed defense tech is no longer niche — it is a cornerstone of modern national security.
📢 Will Europe’s increased defense spending translate into a stronger startup ecosystem, or will the US continue to dominate?🤔
