Supio
AI document intelligence for personal injury and mass tort firms
About
Supio is a Seattle-based legal AI platform built specifically for personal injury and mass tort plaintiff firms. Founded in 2021, it raised $60 million in Series B funding led by Sapphire Ventures with Thomson Reuters Ventures participating, bringing total funding to $91 million. Its Document Intelligence platform combines purpose-built AI models with human expert verification to reduce hallucinations, turning medical records, bills, and case documents into chronologies, demand letters, and case signals. The company cites firms reporting 20-30% higher per-case results. It is specialized to plaintiff-side PI work rather than general corporate law, and pricing is quote-based.
