Summary

American entrepreneur and venture capitalist — co-creator of Mosaic (first web browser) — co-founder of Netscape — co-founder of Andreessen Horowitz (a16z) — the most influential venture capitalist of the last 15 years — author of the Techno-Optimist Manifesto.

Core Contribution

Creates the modern venture capital model as a media-and-services firm — a16z's approach (PR, recruiting, operational support, networks rather than just capital) transformed venture capital from a financing function into a full-service startup accelerator that competitors have since copied.

Key Spikes & Highlights

  • Wrote 'Software Is Eating the World' in 2011 — the thesis (every industry will be transformed by software companies) was considered overreaching in 2011 and is now considered obviously correct; the essay's predictive accuracy rate is higher than almost any major technology prediction essay published in the same era
  • The Techno-Optimist Manifesto (2023) cited Futurism and other movements — critics noted some citations were from fascist-adjacent traditions; the piece illustrated how his maximalist technology optimism struggles with the historical examples it needs to support the argument
