Clio just bought its way into legal research
On 10 November 2025, Clio completed a US$1 billion acquisition of vLex, the legal research platform that had been independently owned by European private equity firm Oakley Capital since 2022, vLex was never part of Clarivate, despite that being a common mix-up. The deal was announced alongside a US$500 million Series G at a US$5 billion valuation, making it the largest M&A transaction in legal-tech history and instantly the thing every practice-management vendor now gets measured against.
The acquisition is real substance, not just a headline number. vLex brings more than one billion editorially enriched legal documents across 110 jurisdictions and its Vincent AI research assistant, layered onto Clio's existing matters, billing, trust accounting and CRM. Clio now reports being trusted by hundreds of thousands of legal professionals in more than 130 countries. A firm evaluating Clio today is evaluating a materially different, and materially stronger, product than the one that existed a year ago.
