Lux Capital invests in companies emerging from the life sciences, physical sciences and computational sciences, including biotechnology, robotics, aerospace, defence and AI infrastructure.

Its investment approach includes small Seeds, Experiments and Optionality investments that let it engage with technology before a conventional venture case is established. The firm also makes thesis-driven investments and backs founders working on technically difficult problems.

Lux’s Riskgaming programme uses researched scenarios to examine how technological developments interact with geopolitics and national security. That perspective is especially relevant for founders whose commercial opportunity depends on scientific progress, industrial adoption or government demand.
