Westlaw (Thomson Reuters)

Background

Westlaw and LexisNexis form a duopoly in legal research, charging large law firms five- and six-figure annual contracts for case-law search. The underlying product is a glorified search engine.

The disruption thesis

LLMs trained on case law can deliver better answers than keyword search, with citations — and at a tiny fraction of Westlaw's price. The wedge is solo and small-firm lawyers who can't afford Westlaw today.
