Theorem Labs combines formal verification with AI to automatically check and prove the correctness of software, addressing the growing 'oversight gap' where AI systems produce code faster than humans can meaningfully review it. Founded in 2025 and backed by Khosla Ventures and Y Combinator, the company's approach — called fractional proof decomposition — allocates verification resources proportionally to the importance of each code component. Their tools are aimed at systems engineering teams in AI labs, GPU-accelerated computing, and electronic design automation who need correctness guarantees before merging code changes.

Theory of Change
Theorem Labs believes that as AI-generated code proliferates, the bottleneck to safely deploying AI in critical systems is the inability to verify code correctness at scale. By making formal verification 10,000 times faster through AI-powered tools, they aim to close the 'oversight gap' between code generation and safe deployment. Their causal chain: faster, cheaper formal verification → more software verified before deployment → fewer bugs and security vulnerabilities in AI-generated code → safer AI systems in critical domains (robotics, drug synthesis, cryptography, etc.).
