Alta Ares raises €50M as European defence tech keeps moving into venture
Alta Ares’ €50 million Series A shows European defence and dual-use technology continuing to attract mainstream venture capital.

European defence tech is moving further into the venture mainstream. Alta Ares’ new round is another sign that investors are treating defence and dual-use infrastructure as a serious startup category.
What happened
Alta Ares raised a €50 million Series A round backed by investors including Air Street Capital, Cherry Ventures, OTB Ventures and Harpoon Ventures. The company is part of a wider wave of European defence and dual-use startups attracting new capital.
Why it matters
Defence technology is increasingly tied to software, data, autonomy, resilience and industrial capacity. As geopolitical pressure rises, investors are paying more attention to companies that can support national security and critical infrastructure.
The bigger picture
Defence tech is no longer only about traditional contractors. Europe’s startup ecosystem is beginning to fund companies that sit between commercial innovation and strategic security needs.
