Jun 2026Undisclosed stageFounders Fund (lead); Sequoia Capital (lead); Air Street Capital; NATO Innovation Fund; 201 Ventures; Doepfner capital; Advent International; Project A Ventures$582M$4.1BStark Defence, a Berlin-based startup developing autonomous strike drones and command-and-control systems, raised €500 million ($570 million) in a funding round led by Sequoia Capital and Founders Fund, with participation from the NATO Innovation Fund, Project A, Air Street Capital, 201 Ventures, Advent International, and Döpfner Capital. The round values the company at €3.2 billion, though some reports suggest valuations as high as €3.5 billion. This brings Stark's total funding to approximately €640–€660 million, up from €140–€160 million prior to this round. Over 80% of the capital will be invested directly into R&D and manufacturing, including new electronic warfare research facilities and scaling production to thousands of systems per month. The strategic rationale centers on strengthening Europe’s defence industrial base, advancing sovereign defence capabilities, and expanding production capacity for loitering munitions and strike drones. Stark was founded in 2024 and is two years old, focusing on kamikaze/kamikaze-style drones and electronic warfare systems. The company operates out of Berlin and is positioning itself as a key player in European military technology amid rising private capital inflows into defence tech.
Feb 2026Undisclosed stageFounders Fund (lead)-$1.2BStark is a German defense technology startup founded in 2024 specializing in armed strike drones. The company recently secured a fresh undisclosed funding round led by U.S.-based Founders Fund with participation from European investors, propelling its post-money valuation above €1 billion ($1.2 billion). This follows a prior $62 million round in August 2025 led by Sequoia Capital that valued Stark at roughly $500 million, bringing total disclosed funding to about $100 million. Backers include Thiel Capital, NATO Innovation Fund, Project A, In-Q-Tel, and Döpfner Capital. Stark employs around 450 people and plans to double its workforce by the end of 2026 to support production expansion. The company has opened a new location in Stockholm after entering the UK market in November 2025. A major framework agreement with the German armed forces is imminent, potentially worth up to $2.8 billion, with an initial €280-332 million booked this year to equip a brigade in Lithuania by end-2026. The unicorn valuation reflects surging European defense demand amid geopolitical shifts, positioning Stark to capitalize on government contracts for advanced drone systems.

Its flagship product, OWE-V Virtus, features vertical take-off, X-shaped wing design, 5kg warhead, and onboard AI for targeting and navigation. Stark focuses on software-defined platforms and AI enabling operators to control multiple systems, emphasizing modularity, rapid deployability, and adaptation to battlefield needs. The company tests systems in Ukraine and plans potential local production. Stark raised $62 million in a funding round led by Sequoia Capital, with participation from Peter Thiel, valuing the company at $500 million post-money and bringing total funding past $100 million. This follows prior raises: €14M ($16.32M) last fall and $15M angel from Peter Thiel in April, at ~€90M ($105M) valuation. Proceeds will accelerate development and deployment of defense technologies, scale production of OWE-V Virtus, enhance AI R&D for targeting/navigation, expand Ukraine testing, open global offices, establish local production if demand grows, and hire engineering talent. Stark recently expanded to the UK with a drone facility and acquired Berlin-based Pleno for autonomous navigation and drone swarming capabilities, positioning it among Europe's fastest-growing defense tech firms amid geopolitical tensions and Ukraine conflict. The defense drone sector gains momentum with demand for scalable, AI-powered systems for European and NATO forces.
