Investment Thesis

Refactor invests in seed-stage hard tech founders who aim to commercialize real science and scale real systems. The firm believes that ‘the most enduring companies are created by founders willing to commercialize real science and scale real systems.’ They focus on companies solving ‘hard but not impossible problems’ at the intersection of computation and physical sciences, with the goal of refactoring—improving efficiency and scalability—within their respective industries.
