Investment thesis

Founded in 2009 on the conviction that 'software is eating the world,' Andreessen Horowitz (a16z) invests from seed to growth stage across AI, bio + health, consumer, crypto, enterprise, fintech, infrastructure, and companies building toward American dynamism. The firm pioneered the 'platform model' in venture — pairing capital with the largest team of operators in the industry (talent, marketing, legal, policy, and finance) dedicated to helping founders at every stage. As stated on their site: 'We invest in seed to venture to growth-stage technology companies… We believe the future belongs to builders, and our job is to make sure they have what they need to build it.' With over $100B+ under management across multiple funds, a16z backs ex-founders and operators who invest by vertical and have 'already solved the problems you're about to face.' The firm's current conviction centers on AI as a driver of abundance, American dynamism (defense, aerospace, manufacturing), crypto/Web3 infrastructure, and the next generation of bio + health breakthroughs. Its Speedrun program targets pre-seed companies with up to $1M checks, while its Growth fund ($22B+ across 5 vintages) backs market leaders at scale.

Notable quotes

We are told to be afraid of technology. We are told that technology takes our jobs, destroys our culture, threatens our wellbeing, and endangers our children. We are told to be suspicious of the people who make technology. We are told that technology is a tool of the powerful, used to oppress the powerless. We believe the opposite: technology is the glory of human ambition and achievement, the spearhead of progress, and the realization of the human potential.

Software is eating the world. More and more major businesses and industries are being run on software and delivered as online services — from movies to agriculture to national defense.

Late-stage venture is not about late-stage companies — it's about late-stage founders. The best founders at the growth stage are those who have already navigated the hardest parts of company building and are now ready to scale with conviction.
