Thiel and Sequoia Bet $570M on German Drones

Stark Defence, the Berlin startup that builds loitering munitions for the German military, closed a €500 million (roughly $570 million) funding round this week led by Sequoia Capital and Peter Thiel’s Founders Fund.

The deal values the two-year-old company at approximately €3.5 billion ($3.65 billion) and brings total capital raised to €660 million. Stark went from a seed round to a $3.65 billion valuation in under 18 months. That pace is unusual even by defense tech standards.

Sequoia, Founders Fund, and NATO Back the Berlin Startup

As The Next Web reported, Sequoia Capital and Founders Fund headlined the round, joined by the NATO Innovation Fund, Döpfner Capital, Air Street Capital, 201 Ventures, Advent, and Project A. Eight institutional investors in a single round is not typical.

The NATO Innovation Fund is the military alliance’s own venture capital vehicle, established to back dual-use and defense-relevant startups across Europe. Its presence alongside two of Silicon Valley’s most prominent funds marks a convergence that would have seemed unlikely five years ago: American tech money and NATO strategic capital betting on the same Berlin startup at the same valuation.

CEO Uwe Horstmann is not a career defense executive. He co-founded Project A, one of Germany’s leading venture firms, before taking the Stark role in October 2025. He also holds a reserve officer commission in the German Armed Forces, which gives him direct visibility into the procurement side of the business.

His quote from the announcement: “The challenge facing Europe is no longer whether we can innovate, it’s whether we can scale.” Stark is backing that with capital allocation. Over 80% of the €500 million goes toward manufacturing expansion and R&D, with a stated target of thousands of systems per month.

Stark hit unicorn status in January 2026, less than six months after its $62 million Sequoia-led seed round in August 2025. The jump from a $1 billion valuation to $3.65 billion in roughly five months reflects how fast European defense procurement is moving right now. Russia’s war in Ukraine has compressed what used to be decade-long procurement cycles into months.

Virtus Loitering Munitions Are Already in Ukraine

Stark’s flagship product is the Virtus, a loitering munition designed to be assembled in ten minutes and deployed autonomously against armored targets. The drone carries a self-detonating warhead, operates without a human in the loop during the terminal phase, and is already confirmed deployed in Ukraine.

That deployment is not a marketing exercise. Ukraine is the harshest real-world test environment for drone systems right now, and operating there means the Virtus has faced actual electronic warfare, actual countermeasures, and actual combat conditions.

Ten minutes matters more than it sounds. In war there’s no time to waste. Two vendors with nearly identical payload specs are the same weapon on paper. Assembly time is the tiebreaker. That ten-minute number isn’t a marketing line. It’s a procurement argument.

Stark’s product line extends beyond the Virtus. The company builds unmanned surface vessels and threat-tracking software for weapons system coordination, making it a broader autonomous weapons platform company rather than a single-product drone maker.

Co-founder Florian Seibel previously built Quantum Systems, one of Germany’s earlier high-profile drone companies, before stepping back to a founding investor role at Stark. The company runs a 40,000-square-foot production facility in Swindon, England, opened in 2025, and maintains operations in Germany, Ukraine, Sweden, and Greece. Stark also acquired Pleno, an autonomous navigation software startup, folding its technology into the broader platform.

Bundeswehr Contracts Give Stark a Real Revenue Base

In February 2026, the German Bundeswehr awarded Stark and fellow defense startup Helsing contracts worth approximately €269 million each to supply drones to the 45th Armoured Brigade stationed in Lithuania.

Framework agreements tied to those contracts could expand to €1 billion per company. That is not speculative revenue. That is an active procurement commitment from a NATO member military, for a specific unit, in a specific location.

The 45th Armoured Brigade in Lithuania sits directly on NATO’s eastern flank, a few dozen miles from the borders of Russia and Belarus. These drones are not going to a training base in Bavaria. They are going to the most contested stretch of NATO territory on the continent.

That contract is also what separates Stark from earlier waves of European defense startups: revenue before the valuation climbed, not after. Many European defense tech companies spent years chasing procurement deals while burning venture money. Stark landed a nine-figure contract before its first birthday.

Stark’s political picture in Germany is more complicated. Founders Fund’s Peter Thiel draws scrutiny from German politicians because of his associations with the Trump administration and his right-wing libertarian positions. That scrutiny has not stopped the contracts or the fundraise, but it will follow the company as it deepens its relationship with the Bundeswehr and pursues procurement contracts across other European defense ministries.

DroneXL’s Take

This is a two-year-old company with a confirmed wartime deployment, a nine-figure government contract, and $570 million in fresh capital from Sequoia and Peter Thiel.

I’ve covered defense drone startups that spent years in prototype phase without a single paying customer. Stark closed a Bundeswehr contract and a half-billion funding round in the same quarter.

This round says one thing clearly: European defense tech is growing fast and the pace won’t slow. They have a live war to test their hardware in real conditions. Stark can call its systems battle-proven today. That is a direct challenge to American drone manufacturing, and the people responsible for that gap need to be paying attention. Starting with the Secretary of War.

The manufacturing claim is the open question. “Thousands of systems per month” is a production challenge as much as a technology one. The 40,000-square-foot Swindon facility and the R&D push are the right moves. But scaling production lines for autonomous strike weapons is not the same as scaling software. Whether Stark hits that output without quality failures is what gets tested under operational pressure, not in a press release.
