Investing in Early-Stage Tech
to Forge Strategic Strongholds.

The next industrial edge isn’t flashy – it’s foundational.
We invest early, stay close and build companies that can handle the world’s toughest problems. If it can’t lead, scale and last, it’s not worth building.

Defence

Space & Aerospace: Developing reusable spacecraft, cutting-edge satellite systems, and next-gen propulsion technologies to position Europe at the forefront of space exploration and security.

Surveillance & Intelligence: Advancing digital twin technology, next-generation surveillance systems, and spacecraft for space security and debris removal, enhancing intelligence and situational awareness.

Enterprise

Quantum & Advanced Computing: Driving innovation in quantum computing, quantum networking, and high-performance computing to enable secure communications and unprecedented computational capabilities

AI & Cybersecurity: Leveraging AI-driven systems for predictive cybersecurity, workplace safety, and informed decision-making to counter evolving threats and strengthen operational resilience.

Industrial

Advanced Materials & Manufacturing: Pushing the boundaries of lightweight materials, integrated photonic circuits, and advanced manufacturing to create stronger, more efficient, and highly capable defence platforms.

Autonomous Systems & Robotics: Innovating in modular robotics, autonomous mobile systems, and unmanned vehicles to enhance automation and operational effectiveness

Europe and Asia Forge New Alliances in Defence Tech
Join Capital’s Partners, Tobias Schirmer and Daniel Carew, recently returned from a productive roadshow in Asia, where we held multiple extensive meetings with defence primes, government representatives and a range of investors. The primary aim of these conversations, which involved strategic partners from South Korea, Japan and Singapore, was to validate our thesis around Europe’s rapidly growing focus on defence tech and resilience.
