Description

Section 32 is a prominent venture capital firm based in San Diego, California, founded in 2017 by Bill Maris, the former CEO and founder of Google Ventures (now GV). The firm distinguishes itself by investing at the convergence of technology, healthcare, and life sciences, leveraging Maris's deep expertise in both venture capital and the tech industry. Their investment thesis centers on supporting companies that are developing groundbreaking solutions to complex challenges, particularly those with the potential for significant societal impact and market disruption.
