2 VCs and 2 funds investing in defense/aerospace
Co-Founder & Partner
Founders Fund
Check: $1M-$100M+ (multi-stage, also invests personally and through Thiel Capital)
The original contrarian VC. 'We wanted flying cars, instead we got 140 characters.' Seeks companies that can become category-defining monopolies in markets others ignore. First principles thinking is non-negotiable. The key question: 'What important truth do few people agree with you on?' Backs revolutionary technology, not incremental improvements. The Venn diagram of 'right' and 'different' is where he invests. Thiel's intellectual framework is deeply philosophical — draws from René Girard's mimetic theory (competition is imitation, and imitation destroys value), Leo Strauss, and libertarian economics. Founders Fund's motto: 'We wanted flying cars, instead we got 140 characters' — a critique of Silicon Valley's focus on trivial consumer apps instead of transformative technology. Thiel distinguishes between 'definite optimism' (having a concrete plan to build a better future) and 'indefinite optimism' (vaguely hoping things get better). He champions the former. Created the Thiel Fellowship ($100K grants for young people to drop out of college and build companies) — alumni include Vitalik Buterin (Ethereum), Austin Russell (Luminar Technologies), and others.
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.
