Axiom Math turns a 7,654-page mathematics library into verified code for AI agents
Axiom Math, a $1.6 billion startup, announced in November 2026 that it had formally verified the Stacks Project, a mathematics library started by Johan de Jong of Columbia in 2005. Its AI agents translated roughly 7,654 pages into about 16 million lines of computer-checked code in Lean, a programming language, keeping every connection between theorems and definitions intact.
Carina Hong, the chief executive, founded Axiom Math in March 2025 after dropping out of a Stanford mathematics PhD program, and the Stacks work points beyond the race to announce solved problems. The library is groundwork for a stated end: verified foundations on which AI agents write software and, eventually, do science. Demand from developers remains a bet, even as Hong challenges coding companies to formalize at this scale.
