Investment thesis

Fathom Fund invests in technology platforms at the pre-commercialization or early commercialization stage, where technical and scale-up risk still exist. It seeks ambitious founders who are scientists and engineers with significant operating experience and radical new approaches, often addressing multiple markets or creating entirely new ones. The firm conducts rigorous technical diligence supported by a broad network of subject-matter experts and industry leaders, and forms independent views about how and when disruption will occur while learning alongside founders. Its partners are business and government leaders across the sectors it targets. Although its primary focus is companies raising their first institutional round, Fathom is positioned to support companies at all stages of their life cycle.
