Supio, the fast-growing AI platform reshaping how personal injury and mass tort law firms manage high-stakes litigation, has raised $60 million in Series B funding, bringing its total to $91 million. The round was led by Sapphire Ventures, with new backing from Mayfield and Thomson Reuters Ventures, a sign that Supio’s AI-first approach is gaining momentum across legal tech and investor circles alike.
Founded on the belief that AI can meaningfully improve legal outcomes and not just speed up paperwork, Supio has carved a niche by combining custom-trained AI with human legal experts to deliver document analysis, drafting, and case intelligence that lawyers actually trust.
In contrast to many generic legal AI tools that struggle with accuracy and hallucinations, Supio’s platform is tailored specifically for the nuanced, document-heavy workflows of plaintiff-side litigation.
