Scaling Past Informal AI - Carina Hong, Axiom Math

With Brandon Anderson, R.J. Haneki, Carina Hong · Sunday, June 7, 2026

This episode features Carina Hong, CEO of Axiom Math, discussing her company's vision for formal verification as the foundation for superintelligence and AGI, backed by a significant Series A funding round. Hong details Axiom's use of Lean to achieve superhuman performance in mathematics, tackles the challenges of specification and mathematical discovery in AI-driven proofs, and introduces the AXL API to foster collaborative formal verification. She also outlines the broad commercial applications of verified AI, particularly in mission-critical hardware and evolving software domains.

Key takeaways

  • AI, particularly Lean-based systems, struggles with highly creative mathematical domains like combinatorics because the necessary steps are often too intuitive and "quite creative," according to Carina Hong. Read more →
  • Axiom Math secured a $200 million Series A funding round, valuing the company at $1.6 billion, to advance "verified AI." Read more →
  • Axiom Math, fresh off a $200 million Series A, aims to move formal verification beyond mere error correction, focusing instead on scaling "brilliance" to achieve superhuman math performance. Read more →
  • AI, particularly formal systems like those based on Lean, struggles with true mathematical discovery—the creative process of formulating conjectures and constructing examples before a formal proof begins. Read more →
  • Axiom Math's AI achieved a perfect 120 score on the challenging Putnam exam in December 2025, outperforming the best human (110 points) and leading LLM Deepseek (103 points). Read more →
