- • European defence tech startups are projected to raise over $1.5 billion in 2025, representing a high watermark for sector investment across the region according to Bessemer's recent report.
- • Bessemer's investment thesis extends beyond drones to encompass space tech, industrial manufacturing, aerial defence systems, and command-and-control software platforms—broadening the addressable market for founders beyond single-category solutions.
- • Alex Ferrara, Managing Partner at Bessemer's London office, leads the firm's European expansion strategy, bringing 20 years of investment experience across B2B SaaS, cybersecurity, deep tech, and defence sectors.
- • Market observers debate whether drone sector valuations reflect genuine demand—Ukraine alone targets 4.5 million units for 2025—or indicate early-stage oversupply relative to the broader defence tech opportunity Bessemer is positioning around.
Summary
Bessemer Venture Partners is significantly expanding its European defence technology footprint, leveraging conviction in a sector experiencing heightened institutional capital flows. The firm's recent $100M Series B investment in Auterion, a defence tech company, alongside its publication of a European Resilience Roadmap, underscores a strategic pivot to capture growth in a fragmented but rapidly maturing market.
According to Bessemer's analysis, European defence tech startups are expected to raise in excess of $1.5 billion throughout 2025, representing what the firm characterizes as a "high watermark" for regional sector investment. This capital concentration reflects broader geopolitical shifts and modernization cycles driving procurement and innovation across European defence ecosystems. Alex Ferrara, Managing Partner based in Bessemer's London office and leader of the firm's European investment practice, articulated the firm's positioning at the Resilience Conference 2025 alongside Auterion CEO Lorenz Meier.
Critically, Bessemer's investment thesis extends well beyond the drone category that has captured disproportionate media attention. While observer debate persists regarding potential oversupply in unmanned aerial systems—with Ukraine targeting 4.5 million unit production in 2025—Bessemer's target technology stack encompasses space tech, industrial manufacturing, aerial defence platforms, and software/hardware for command-and-control systems that orchestrate front-line operations and strategic campaigns. This broader categorization creates a substantially larger investment funnel and opportunity set for founders and companies across multiple subsectors rather than concentrating exposure in a single vertical.
Ferrara brings two decades of venture experience investing across B2B software, cybersecurity, and latterly deep tech and defence. His leadership of Bessemer's European expansion reflects the firm's confidence in the region's technical talent pool and the structural tailwinds supporting defence technology innovation, positioning the partnership for sustained deal flow in a sector that remains early relative to its long-term growth trajectory.
