What it is
vLex is a global legal intelligence platform acquired by Clio for US$1 billion in November 2025 — the largest M&A transaction in legal technology history. Clio simultaneously raised $500M Series G at $5B valuation. vLex provides access to one of the world’s largest collections of legal and regulatory content across 100+ countries, powering research, citation checking, knowledge management, and due diligence. Core AI product: Vincent AI — generative legal assistant with smart search, brief analysis, document summarization, and multimodal capabilities (audio/video analysis added Winter ‘25). Vincent Studio allows firms to build bespoke AI workflows. vLex merged with Fastcase in 2023, gaining distribution through US state bar associations (free access for bar members in many states). SOC 2 Type II + ISO 27001:2022 certified (CertPro audit). Zero data retention with LLM providers. GDPR ready with data residency controls. ~25K LinkedIn followers. VLAIR Benchmark Study highlighted strong Vincent AI performance in document Q&A. Reddit sentiment positive: ‘I still use vLex (Vincent AI) and Fastcase.’ Bar association channel makes this the most accessible legal research AI for solo/small firms. Post-acquisition, Clio Work is grounded in vLex legal database. Product strategy post-Clio acquisition still evolving.
