About This Fund
Lux Ventures IX is the ninth flagship venture capital fund raised by Lux Capital, the New York-headquartered science and technology-focused venture firm founded in 2000 by Josh Wolfe and Peter Hebert. The fund closed on January 7, 2026, raising $1.5 billion in capital commitments — Lux Capital's largest fund to date — bringing the firm's total assets under management to approximately $7 billion. The raise was completed in approximately three months, reflecting strong demand from the firm's established institutional LP base. Lux Ventures IX backs founders working at the frontier of science and technology in sectors that others find too hard, too early, or too complex to evaluate.
Lux Ventures IX deploys capital across the full company-building arc, from early-stage founding rounds through growth, targeting companies in aerospace, defense, biotechnology, life sciences, artificial intelligence, automation, and industrial technology. The fund focuses on areas where deep scientific and engineering expertise intersects with scalable commercial potential, particularly in dual-use technologies with applications in both defense and commercial markets. Lux Capital's 44-person investment team brings specialist research capabilities across these hard-tech verticals, and the firm takes a hands-on approach to supporting founders through product development, team building, and commercialization of breakthrough technology.
Since founding in 2000, Lux Capital has built one of the most recognized franchises in deep-tech venture investing, generating notable exits across synthetic biology, robotics, AI-enabled healthcare, and advanced materials. Prior funds including Lux Ventures VI through VIII delivered strong performance during periods of rapid technology adoption. The successful close of Lux Ventures IX at $1.5 billion — the firm's largest fund ever and a significant step up from prior vintages — underscores continued LP confidence in Lux Capital's differentiated deep-tech strategy and the team's ability to identify and support frontier science companies.
