General Partner, American Dynamism
Andreessen Horowitz (a16z)
Check: $1M-$100M+ (from $2.5B+ American Dynamism fund)
Leads a16z's American Dynamism practice — a $2.5B+ fund (expanded from $600M in 2023) backing companies that support national interests. Believes the most important companies of the next decade will be built at the intersection of technology and national security. Patriotic tech thesis: the best founders don't just build for consumers, they build for the country. Katherine argues that Silicon Valley abandoned hard, important problems for consumer social apps and that the pendulum is swinging back. The name 'American Dynamism' is intentional — it's about restoring the dynamism that built America's infrastructure, defense, and industrial capacity. She sees a generational opportunity as government procurement modernizes and defense budgets prioritize technology over legacy systems. Has written extensively about how the best founders she meets are motivated by mission, not just money.
Co-Founder & Managing Partner
Lux Capital
Check: $1M-$50M+
'Atoms, not bits.' The biggest opportunities are in companies that manipulate the physical world, not just software. Willing to fund multi-year R&D timelines. Just raised the firm's largest fund ever ($1.5B, Jan 2026, oversubscribed). Invests at the intersection of science and engineering where structural technical advantages create durable moats. Core belief: the 'directional arrow of progress' in science is inevitable — you can bet on where science is going because it only moves forward. Lux looks for 'narrative violations' — moments when consensus is wrong and reality is about to prove it. Josh believes the best founders have 'a secret' — proprietary technical insight that others can't see or don't believe. Has been vocal that the defense tech renaissance is just beginning, not a trend.
