How Ricursive Intelligence raised $335M at a $4B valuation in 4 months

Ricursive Intelligence, founded by ex-Google Brain and Anthropic engineers Anna Goldie and Azalia Mirhoseini, has raised $335 million at a $4 billion valuation in just four months. The startup builds AI tools that design chips, not the chips themselves, targeting Nvidia, AMD, and Intel as customers. Their pedigree includes creating Google's Alpha Chip, which automated a year-long chip layout process into hours and helped design three generations of Google TPUs.
