Documented cause
Casetext built CARA AI for legal research and launched CoCounsel in early 2023 as one of the first GPT-4 powered legal AI tools. Despite impressive product-market fit and $64M in total funding, the company accepted acquisition by Thomson Reuters in June 2023 for $650M. The standalone Casetext platform was integrated into Westlaw products within 18 months, ending its independent existence and the direct-to-attorney subscription model it championed.
Lesson
