Overview

Axiom builds verified AI technology intended to make AI-generated software provably safe and correct. Its approach trains AI systems to generate formally verified outputs in Lean, a programming language used for mathematical proofs, rather than relying on probabilistic code that only appears plausible. The company targets organizations adopting AI coding tools, particularly where software may be used in critical infrastructure or security-sensitive systems. Axiom raised a $200 million Series A led by Menlo Ventures at a $1.6 billion valuation, positioning it around the emerging category of verifiable AI for code safety.
