Investment thesis
a16z invests from seed to growth across AI, enterprise, consumer, fintech, bio/health, crypto, games, and American Dynamism, seeking non-consensus founders building transformative companies.
Focus narrative
a16z's founding thesis, "Software is eating the world," has evolved to "AI is eating software." The firm seeks non-consensus founders building companies with bold ideas that most people doubt will work. AI-related companies represented over 50% of new deals in 2025, with 440+ AI companies in the portfolio. Key focus areas include AI/ML (dominant), consumer (23% of portfolio), enterprise (22%), fintech (18%), bio + health (14%), crypto (13%), games, and American Dynamism (defense, space, manufacturing, robotics). The firm is truly stage-agnostic with dedicated early-stage and growth vehicles.
Value beyond capital
a16z pioneered the "platform" VC model with one of the largest operating teams in venture capital. Support includes executive talent recruiting, media and marketing resources (including a16z's own podcast network and editorial team), Fortune 500 introductions, technical talent network, and go-to-market support. The Speedrun accelerator invests up to $1M per company across 60 startups per cohort, now open to all industries. The firm also launched a Biotech Ecosystem Fund with Eli Lilly (up to $500M) and provides crypto-specific operational support through a16z Crypto.
