Side-by-side comparison of AI visibility scores, market position, and capabilities
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.

About
Neos is a cloud-based legal practice management platform designed specifically for personal injury and plaintiff-side law firms, developed and marketed by Assembly Software (formerly known as Assembly Neos, a company formed from the merger of NexFirm and Assembly). Assembly Software focuses exclusively on legal technology for personal injury firms, building a practice management platform around the specific workflow complexities of PI litigation—including medical records management, lien tracking, settlement processing, HIPAA-compliant client communication, and mass tort multi-plaintiff matter grouping. Neos was developed as a modern, cloud-native successor to AbacusLaw and Amicus Attorney, legacy desktop practice management products that Assembly Software also owns.\n\nNeos's platform provides matter management with PI-specific intake workflows, automated document generation for standard PI forms, medical record request tracking, treatment and provider management, demand letter tools, settlement management with distribution calculation, and a client-facing portal for status updates and document collection. The platform's lien management module tracks Medicare, Medicaid, and health insurance liens associated with personal injury settlements—a workflow requirement unique to PI practice that general practice management tools handle poorly. Neos integrates with e-signature providers, medical records retrieval services, and legal payment processors, and includes reporting tools for case stage pipeline management and staff productivity.\n\nNeos competes with Filevine, Litify, and Needles (owned by Assembly) in the personal injury law firm case management market. Assembly Software's consolidated portfolio—spanning multiple legacy and modern legal practice management products with shared PI market focus—gives it a migration path for firms moving from legacy desktop products to Neos's cloud platform. For personal injury law firms evaluating cloud practice management solutions that genuinely address PI workflow complexity rather than adapting general tools, Neos offers a purpose-built modern platform from a vendor with deep PI market specialization.
