System.One

System.One is a pre-seed venture capital firm based in Berlin, Germany, dedicated to investing in exceptional founders who combine early technical ideas with bold missions and significant potential impact. The firm focuses on leading the first round of financing, often investing as early as an idea, with a typical investment size between €500,000 and €3 million. Their investment areas include SaaS, AI, data & analytics, and security.

Operating as a solo-GP fund under the leadership of Maximilian Claussen, System.One partners with founders at the inception stage, emphasizing product and technology at the core of their investments. The firm maintains a global mindset and reach, with a portfolio that spans across Germany, the United Kingdom, the United States, and Finland. System.One's approach is to be deeply engaged with a small number of commitments, ensuring high alignment and trust with the founders they support.

The firm's investment philosophy is rooted in the belief that early-stage venture capital should mirror the qualities of judgment over process, conviction over consensus, and art over standardization. System.One aims to serve founders who recognize the human drive behind every ultimate success, providing not just capital but also strategic guidance to navigate the challenges of early company building.
