About

Katherine Boyle co-founded Andreessen Horowitz's American Dynamism practice, which invests in defense, aerospace, manufacturing, energy and other companies tied to the national interest. A former Washington Post reporter, she previously co-led the seed practice at General Catalyst, where she invested in the earliest rounds of Anduril and Vannevar Labs. Her essays on dynamism and seriousness in American institutions have shaped how a generation of founders talks about building for the state.
