A Shahed attack drone costs tens of thousands of euros. The missiles traditionally fired to shoot one down can cost a million or more. A French startup has raised €50mn to fix that maths.
Alta Ares, a Paris-based defence-technology company founded in 2024, said on Tuesday it had closed a €50mn round led by Air Street Capital, with Cherry Ventures, OTB Ventures, and Harpoon Ventures joining and existing backers renewing their commitments.
The company builds AI-guided interceptors designed to detect, track, and destroy drones, cruise missiles, and glide bombs, and says its systems are already deployed across three active conflict zones in Europe, the Middle East, and Asia.
The pitch rests on the inverted economics of modern war. Cheap, mass-produced autonomous weapons have made the old air-defence model, firing exquisite, expensive missiles at disposable targets, unsustainable. NATO allies, Alta Ares notes, now face coordinated salvos that can combine more than 600 drones and dozens of missiles in a single night.

The answer, it argues, is interceptors cheap and adaptable enough to match that tempo.
“Modern warfare is defined by speed, mass, and, above all, the capacity for continuous adaptation. Alta Ares was born from this operational reality directly on the battlefield,” said Hadrien Canter, chief executive and co-founder. “This round provides us with the resources to accelerate our industrialisation, product development, and international expansion.”
The company fields two interceptors. X-Lock is a short-range system, with a roughly 15km radius, built for Shahed-136-type drones; Black Bird is a faster, turbojet-powered interceptor with a 30km reach, aimed at harder targets such as KH-101 cruise missiles and FAB-500 glide bombs.
Both are engineered to work in arctic and desert conditions, and Alta Ares says they have been combat-tested intercepting Russian drones over Ukraine, where constant battlefield feedback sharpens its AI. That operational record is its core selling point against a growing field of autonomous drone-killers.
It also carries some institutional weight for a firm this young. NATO handed Alta Ares an innovation award in March 2025, and its advisory board includes Philippe Lavigne, a former chief of staff of the French Air and Space Force and former NATO Supreme Allied Commander Transformation.
The new money will fund industrial scale-up, more hires by year-end, and offices in the Middle East and Asia, alongside production in Toulouse and Kyiv.
Air Street Capital, the AI-focused fund led by Nathan Benaich that has backed the likes of Wayve and ElevenLabs, framed the deal in sovereignty terms.
“Alta Ares embodies a new generation of European defence players: companies capable of rapidly developing sovereign, combat-proven systems that integrate cutting-edge AI,” Benaich said, calling it a potential “global leader in counter-UAS.”
The raise lands in the middle of a European defence-tech boom that has seen the sector’s funding more than double, and in which startups are scrambling to plug the continent’s air-defence protection gap.
So far that money has flowed overwhelmingly to Germany, which captured around 90 per cent of the continent’s defence-tech investment in early 2025; Alta Ares is one of France’s louder answers. Its roots, like much of the new wave, run through Ukraine, where battlefield necessity has turned the country into a defence-tech proving ground.
The caveats are worth stating. Alta Ares is barely two years old, and its combat-proven record, contract wins, and deployment claims are the company’s own. Defence valuations are running hot, and fielding AI systems that autonomously identify and destroy targets raises governance questions the whole sector has yet to fully answer.
But the underlying bet is hard to argue with: in a war defined by cheap drones, the side that can intercept them cheaply, and iterate weekly, has the advantage.
Alta Ares is wagering Europe would rather build that capability than import it.
