Lux Capital Announces Lux Ventures IX, its Largest Fund to Date

Lux Capital, a Venture Capital Firm, started in 2000, investing in opportunities at the frontier of science and technology that others find too hard, too early, or too confusing, led by Peter Hebert, Josh Wolfe, and others, has announced its largest fund to date, Lux Ventures IX, a $1.5B commitment to investing in the people turning sci-fi into sci-fact. 

Entire sectors, from aerospace and biotech to defense and industrials, are being rebuilt by a bold new generation of scientists and engineers. As markets concentrate around fewer companies and larger checks, Lux’s focus on the craft of company-building remains unchanged.

Science doesn’t scale itself. Turning a breakthrough known to a few into something the world relies on requires a partner willing to deploy the first $100K and the last $100M, stay through the full journey, and mobilize a network of driven founders who see capital as a tool, not the product.

Lux now manages $7B with a 44-person team, backing overlooked founders, choosing conviction over consensus, and building alongside rebels of science and tech at every stage. We’re grateful to our LPs and to the founders who entrust us with their life’s work. The mission continues with even greater momentum.

Compute, automation, and biology have now matured into scalable engineering disciplines. What was once considered fringe deep tech has become core infrastructure. With new talent, tools, and industrial capacity, the most advanced technologies across the physical, computational, and life sciences can now be transformed into enduring businesses.
