About
Supio is a San Francisco-based legal AI company that emerged from stealth in August 2024 with a platform purpose-built for personal injury and mass tort law firms. The company was founded on the observation that personal injury litigation requires intensive review of large volumes of medical records, deposition transcripts, accident reports, and expert opinions — work that is time-consuming, expensive to staff, and prone to inconsistency when done manually. Supio built its CaseAware AI platform to ingest, analyze, and synthesize these document types at scale, enabling law firms to handle more cases with greater accuracy and speed.\n\nSupio's CaseAware platform automates medical record review, chronology generation, damages analysis, and case summarization — the core analytical workflows in personal injury litigation that have historically required paralegal and associate attorney hours. The system is trained on the specific document types and legal frameworks relevant to personal injury and mass tort practice, enabling it to identify clinically relevant facts, causation arguments, and settlement-relevant data points that generic document review tools miss. Supio integrates with major case management systems and provides outputs structured for immediate use by attorneys and litigation support teams.\n\nSupio has raised $91 million in total funding and achieved 4x ARR growth since its August 2024 stealth launch, reflecting rapid adoption among personal injury and mass tort firms that see AI as a competitive necessity for caseload scaling. The personal injury legal market processes hundreds of billions of dollars in claims annually in the US, with document review representing one of the largest cost centers for plaintiff firms. Supio's domain specificity, fast growth trajectory, and focus on a high-value, underserved legal vertical position it as the leading AI platform for plaintiff-side litigation.
