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.

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.
