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.
