Thesis
Andreessen Horowitz's Infrastructure Fund, alongside related vehicles like the Machine Age Fund and AI Infrastructure Fund, focuses on the critical physical infrastructure enabling the AI revolution. Their thesis, evolving from 'software is eating the world' to 'AI is eating software,' highlights the strain on existing computational and data paradigms. They invest in compute (chips, memory, networking, storage), data systems, robotics, power systems, data centers, semiconductors, hardware, defense, and aerospace. The fund targets investments across all stages, from pre-seed to growth and scale-ups, with a US-centric geographic focus for domestic manufacturing and energy. Their strategy involves leading or co-leading rounds in capital-intensive, long-timeline companies, backing founders with deep technical expertise. The firm manages over $100 billion in AUM, with specific infrastructure funds ranging from $1.1 billion to $1.7 billion. Typical check sizes for infrastructure investments can range from $500K to $350M+, with a focus on early application bets and foundational model infrastructure.
