## The use case: how Proof deploys Ironclad

Proof uses Ironclad to manage its contract lifecycle, including an AI Contract Review Agent that gives attorneys a first pass on NDAs based on the team's own playbook. It also keeps post-signature obligation data in Ironclad, extracted from agreements by AI, so teams across the company can search and act on it.
