What is formal verification

Mathematical proofs that guarantee a system behaves as intended - not on sampled inputs, but in every possible case. Tools like Lean make it possible to machine check the correctness of mission-critical software and advanced math proofs.

Formal verification, applied

Cajal is scaling formal verification to accelerate scientific discovery. We deploy advanced AI systems - grounded in formally verified mathematics - to high-impact applied domains, starting with quantum computing and finance.
