Investment thesis
PT1 invests at day one in founders solving structural problems across energy, buildings, and infrastructure, with a focus on InfraTech, electrification, and AI-driven industrial systems. The firm believes aging European infrastructure, cheaper clean energy, and mature LLMs create major opportunities to upgrade the physical world. Leveraging deep sector fluency, PT1 moves quickly and can (co-)lead rounds of up to €4M, offering founders capital plus strategic, financial, and operational support. Its ecosystem includes LP investors who can become key customers and venture partners who have built and scaled companies, differentiating it from generalist growth investors.
