Supio builds agentic AI software purpose-built for personal injury and mass tort plaintiff law firms. Its platform, Supio Agent, ingests medical records, depositions, and case files to automatically produce medical chronologies, demand letters, case analyses, and litigation drafts, freeing attorneys from manual document review. The company emphasizes enterprise-grade security (SOC 2 Type II, HIPAA, GDPR) and guarantees client data is never used to train foundation models. Since emerging from stealth in August 2024 with a $25M Series A, Supio has grown ARR 4x and now serves many of the top plaintiff firms in the United States. In April 2025 it raised a $60M Series B led by Sapphire Ventures, bringing total funding to $91M, with strategic backing from Thomson Reuters Ventures.
