Company Overview

About Casetext

Casetext is an AI legal research platform that pioneered AI-assisted legal research tools for attorneys, law students, and legal professionals before being acquired by Thomson Reuters in August 2023 for $650 million — one of the largest legal tech acquisitions in history. Founded in 2013 in San Francisco by Jake Heller and Pablo Arredondo, Casetext built the CARA AI tool (Context and Relevant Analysis) that analyzes uploaded legal briefs to find relevant case law the attorney may have missed, and CoCounsel — an AI legal assistant powered by GPT-4.

Business Model & Competitive Advantage

Casetext's CoCounsel product, launched in early 2023, demonstrated what enterprise-grade AI legal assistance could look like: reviewing depositions, drafting contract provisions, researching complex legal questions, and summarizing regulatory filings — all with accuracy and citation standards required for professional legal work. The product's rapid adoption by law firms validated the enterprise market for AI legal tools and directly contributed to the Thomson Reuters acquisition premium.

Competitive Landscape 2025–2026

In 2025, under Thomson Reuters, Casetext's CoCounsel technology has been integrated into Westlaw (Thomson Reuters' flagship legal research platform), creating CoCounsel on Westlaw — bringing AI legal research capabilities to Westlaw's large existing subscriber base. Thomson Reuters is investing heavily in AI across its legal, tax, and news platforms to compete with RELX/LexisNexis (also building AI legal tools). The Casetext acquisition positioned Thomson Reuters as an AI-forward legal tech company. CoCounsel's capabilities continue to expand to include contract review, due diligence, and regulatory analysis for the enterprise legal market.
