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.
Legal AI for plaintiffs firms identifying mass tort and class action opportunities; AI analysis of regulatory data and adverse event reports to surface high-value litigation claims before competitors.
About
Darrow is a legal AI platform that helps plaintiffs' law firms and mass tort litigation groups identify and pursue large-scale legal claims by automatically analyzing datasets for patterns that indicate potential class action suits, multi-district litigation (MDL) opportunities, or mass tort cases — using AI to surface claims that would require enormous manual review to identify in traditional legal research. Founded in 2020 in Tel Aviv, Israel by Evyatar Ben Artzi and Gal Gonen, Darrow has raised approximately $35 million and targets plaintiffs' law firms and litigation funders who want to find and develop high-value cases more efficiently.\n\nDarrow's AI system monitors regulatory filings, court documents, government databases, news sources, and adverse event reports to identify emerging litigation opportunities — such as a pattern of product safety complaints that could form the basis of a class action, or regulatory enforcement actions that create plaintiff claims. The platform helps attorneys evaluate claim merit and potential damages before investing significant resources in case development. Darrow calls this "justice intelligence" — using AI to surface deserving claims that might otherwise go unfiled because attorneys lack the tools to identify them efficiently.\n\nIn 2025, Darrow operates in the emerging legal AI and litigation intelligence market alongside CaseText (acquired by Thomson Reuters), Lex Machina (LexisNexis), and general legal AI tools like Harvey AI for litigation-focused AI applications. The plaintiffs' side of the legal market is a significant opportunity for AI — mass tort and class action law firms handle billions in settlements and have strong incentive to identify high-merit cases early. The 2025 strategy focuses on expanding its claim identification coverage to more regulatory databases and adverse event sources, growing partnerships with major plaintiffs' firms and litigation funders, and expanding internationally.
