Ukraine's Wartime Drone Sector Becomes a Global AI Arms Lab

Swarmer, a three-year-old Ukrainian drone-software startup, saw its shares spike nearly 1,000% over their first three trading sessions after going public in March 2026 — the clearest signal yet that global capital has decided Ukraine's battlefield is where the future of military AI is being written.

The company builds AI software that lets groups of drones coordinate with less human direction. Serhii Kupriienko, its cofounder and then-CEO, previously led artificial intelligence teams for Amazon's Ring division in Ukraine. He hit on the idea in early 2023, after watching FPV drones spread across the front while remaining dependent on human pilots. Drones caused less than 10% of battlefield casualties in 2022; by 2025, that figure had risen to as much as 80%.

Kupriienko called Alex Fink, an American businessman he had known for over a decade, for advice on turning the idea into a company. Fink sent back a five-page plan. Kupriienko called him again and proposed they build it together. "You can't develop something that works sitting in the garage in California," Kupriienko says. "You have to be present here to work daily with the front lines." He recalls once changing code while a drone was still hovering over a target after its payload failed to release.

The market around him has scaled fast. Ukraine's defense tech market reached roughly $6.8 billion last year, with drones accounting for most of it, according to the Kyiv School of Economics Institute. Ukraine-linked defense and dual-use startups attracted more than $776 million in venture money in 2025 — a record, per PitchBook — bringing total investment since 2022 to roughly $1.8 billion. The country's annual defense production capacity has grown from about $1 billion in 2022 to $35 billion by 2025.

Kyiv-based venture fund D3 was one of Swarmer's earliest backers, investing at the preseed stage in late 2023 and later joining its $15 million Series A in September 2025. D3 launched in July 2023 with about $19 million, counting former Google CEO Eric Schmidt as its most prominent early backer; Schmidt reportedly contributed $10 million after a trip to Ukraine. "Ukraine has continually out-innovated the enemy," he wrote at the time, predicting that "the future of war will be dictated and waged by drones."

U.S. investors including Schmidt and Palantir CEO Alex Karp are pouring money into Ukrainian defense tech. The Pentagon, which saw conventional U.S. troops beaten handily by Ukrainian drones in a recent war game, has requested more than $54 billion for its Defense Autonomous Warfare Group.

Amazon for war

The state's procurement machinery has kept pace. Brave1, the government-sanctioned defense tech platform launched in April 2023, counts more than 500 UAV manufacturers and 200 AI product-makers. Its online marketplace, Brave1 Market, offered more than 4,000 items by July 2026, with in-stock equipment reaching frontline units in an average of eight days, down from roughly two weeks. In June alone, units placed about 5 billion hryvnias, or $111 million, in drone orders through the system, according to Business Insider. Under the Electronic Points program, units earn credits for verified battlefield results and redeem them for additional gear. "The supplies flow to those who most effectively use those supplies," a senior Brave1 official says.

The Defense Ministry created a new AI center, A1, in March, led by Danylo Tsvok. Its most ambitious project, a decision-support platform called SPECTR, is beta testing across several units; Reuters reported that A1 ultimately aims to build a single operating system recommending decisions from frontline units up through strategic command.

Hard physics

Foreign entrants have learned humility. Shield AI's V-BAT reconnaissance drone arrived in 2023 without its AI-pilot software and lost GPS and communications links to Russian electronic warfare — exactly what happened. "Anything reliant on GPS failed in that environment," says Shield cofounder and president Brandon Tseng. Ukraine's approach, he says, "has had to be bottoms-up." Still, Ukraine "literally have[s] the best tactical drones in the world," he argues.

Brian Streem, founder of Vermeer, which builds vision-based navigation systems that keep drones flying when GPS is jammed, has spent significant stretches of the past two years in Ukraine. Vermeer received more than $7 million in U.S. Air Force funding, later raised $12 million, and The New York Times reported in 2025 that the Pentagon had proposed putting its navigation technology on new American deep-strike drones. Streem dismisses hype around a drone "orchestration layer" as "Fantasyland," and insists the unglamorous engineering — vibrating cameras, overheated computers, bombed airfields — decides what works: "We're fighting a war in a physical world."

RAND researcher Michael Bohnert flags the industry's central open question. Companies that spent years building cheap, easily exported weapons may have neither the finances nor the incentive to pivot once the fighting stops. "They're going to have to sell somewhere," he says. The Brave1 official sees the answer in exports under a government framework announced in July: "We rearm the world."
