SquareOne describes itself as a fund for makers and doers, backing that up with a concrete first-customers guarantee for founders, a habit of investing in overlooked European hubs such as Dresden, Bochum, Giessen, Poland, the Czech Republic, and Italy, and a preference for technical founding teams with strong engineering and IP—sometimes investing the same day a company is legally founded. It has also built a clear thesis around open-source companies and deep tech, backing hard-to-underwrite bets like Semron’s new chip architecture and Edgeless Systems’ confidential-computing work, and its own history—self-funded through freelancing before becoming an institutional fund—reflects the operator-first mindset of a team that includes former entrepreneur Georg Stockinger and Paua Ventures founder Christian Buchenau.
