About
Darrow AI is a legal intelligence platform that applies machine learning to identify, qualify, and develop mass tort and class action litigation opportunities. Founded to address the inefficiency with which plaintiff law firms discover viable large-scale cases, Darrow ingests public and proprietary data — regulatory filings, court records, news, social signals — and surfaces actionable litigation intelligence that would take armies of paralegals months to compile manually.\n\nThe platform gives plaintiff firms a continuously updated pipeline of mass tort opportunities, complete with damages estimates, claimant population analysis, and expert sourcing support. It targets plaintiff-side litigation boutiques and large personal injury firms that compete on case acquisition and portfolio quality. By quantifying potential case value and identifying optimal entry timing, Darrow helps firms allocate litigation capital more efficiently — a significant advantage in contingency-fee practices where capital deployment decisions directly determine firm economics.\n\nDarrow has identified $18B+ in potential litigation value across its platform and achieved cash-flow positivity since 2023 — a rare distinction for a legal tech startup. With 80 law firm clients and $91M raised including a $60M Series B, Darrow has established itself as the leading AI intelligence layer for mass tort litigation. Its combination of proprietary data pipelines, proven financial sustainability, and deep law firm relationships makes it a durable competitive position in a legal market increasingly won by information asymmetry.
