European Defense Sovereignty Starts in the Factory: Stark’s Uwe Horstmann and Johannes Schaback

Market Context & Strategic Shift

• Europe has reached a consensus that it must assume greater responsibility for its own defense, driven by U.S. advocacy and the realization that deterrence is essential for peace.
• The conflict in Ukraine demonstrated a shift toward software-driven, AI-enabled, and inexpensive weapon systems, necessitating a change in procurement processes from traditional "battleship" style to agile defense innovation.
• Founders Uwe and Johannes (Stark) identify this as a structural, sustainable shift in European defense procurement rather than a temporary trend, citing the necessity of continuous innovation ecosystems.

Stark's Business Model & Early Success

• Stark secured billions of dollars in contracts within 18 months of its founding, an unprecedented pace for the defense sector.
• The company operates on a "venture-first" model, funding product development internally via Sequoia and other investors rather than relying on government R&D grants.
• Stark distinguishes itself by designing products for mass scalability from day one, treating factory production as an integral component of deterrence.

Customer-Centric Product Development

• Stark integrates closely with end-users (soldiers and tactical units) in Ukraine and European forces to gather operational feedback, prioritizing the user over the bureaucratic buyer.
• The company runs a portfolio of 10–15 distinct programs, including strike drones and unmanned boats, treating them like startup ventures within the larger organization.
• A specific example of user-centric design involved replacing "beautiful" plastic transport boxes with wooden ones because soldiers required wood to heat their shelters in winter.
• The team operates on a "make or break" feedback loop, rapidly iterating based on soldier critique, even when feedback is negative (e.g., "this is absolute shit").

Engineering & Organizational Structure

• Stark organizes as an engineering company with autonomous "programs" acting as startups, supported by a central "capability team" layer for shared infrastructure (e.g., GNSS-denied navigation, object classification).
• The company achieved sub-meter precision in strike drones through tight hardware-software integration and real-time parameter tuning for compute and memory allocation.
• Following a regression in the "Virtus" system during a high-stakes Bundeswehr test, Stark conducted an all-hands, three-shift operation in cold weather to achieve three consecutive perfect strikes within two weeks.
• The organization hires from diverse backgrounds (traditional industry, universities, startups, government) to blend defense knowledge with startup agility, aiming to employ 700+ staff within two years.

Technology & Autonomous Systems

• Products utilize AI for mission planning, swarm communication, and target engagement, ranging from strike drones to unmanned naval systems.
• The company adheres to NATO's principles for responsible AI, implementing hard-coded safeguards (based on IEC 61508 and autonomous driving standards) to restrict actions to operator intent.
• Systems are designed for modularity, allowing integration of various suppliers and components, including infrared and electro-optical sensors, to maintain resilience against supply chain disruptions.
• Future roadmaps include leapfrogging speed, enhancing on-device AI compute, and expanding capabilities into the electromagnetic spectrum via software-defined radios.

Supply Chain & Manufacturing

• Stark optimizes for both time-to-market and production readiness by "shifting left" on manufacturability, avoiding the "formula one" pitfall of unscalable prototypes.
• The company prioritizes component resilience over using the absolute latest technology, sourcing top-quartile parts that are procurable in large numbers.
• Stark balances vertical integration to solve scalability issues while leveraging external supply chains to root production in procurement countries for resilience.

Capital & Future Outlook

• Stark intends to invest approximately €600 million over the next 36 months, rivaling the core R&D spending of established European primes despite being a startup.
• The company is exploring new contractual models similar to cloud services, involving pre-paid manufacturing capacity and continuous software updates to enable massive surge scaling during conflicts.
• The long-term mission is to become a pillar of the Western defense architecture, fostering an innovation ecosystem that restores Europe as a strong, independent ally to the US.
• Founders anticipate that successful European defense innovation will lead to a new era of transatlantic cooperation and a return to global stability.
