Legal software company Clio has surpassed $500 million in annual recurring revenue, marking one of the largest scale milestones in the legal technology sector. The announcement follows a $500 million Series G funding round led by New Enterprise Associates at a $5 billion valuation, as well as Clio’s $1 billion acquisition of vLex, which the company described as the largest M&A transaction in legal technology history.
The milestone reflects a broader acceleration for legal technology as law firms, corporate legal departments, and government legal teams adopt AI-driven tools at a faster pace. Clio now serves hundreds of thousands of legal professionals across more than 130 countries, with growth extending across solo practices, mid-sized firms, large law firms, and in-house legal teams.
Founded in 2008 by Jack Newton and Rian Gauvreau, Clio began by helping law firms move their operations to the cloud. The company has since expanded into a broader operating platform for legal work, introducing its Intelligent Legal Work Platform in 2025 to connect client acquisition, matter management, legal service delivery, and firm operations within one system.
Clio’s recent product growth has been tied to the rollout of agentic AI capabilities across its platform. The company said its AI can now execute complete legal workflows from a single instruction by drawing on matter context, relevant documents, and legal data already within the system. That capability moves the platform beyond task-level assistance and into more automated workflow execution.
“Reaching US$500 million in ARR while accelerating, profitably, gives us the conviction to invest further, faster,” said Curt Sigfstead, Chief Financial Officer at Clio. Founder and CEO Jack Newton said current legal technology decisions will compound over the next decade, adding that “the firms that make that decision today will be the ones defining what legal looks like a decade from now.”
