Jack Newton and Rian Gauvreau met as kids on a playground. Their first joint venture was an aerospace company named Newton-Gauvreau Aerospace.
In 2008 they started Clio, run by Themis Solutions Inc. The idea was to sell practice management to lawyers as a monthly cloud subscription, at a time when law firms kept everything on local servers.
Clio raised $20 million in March 2014. Over the next decade it widened from case management into billing, intake, payments and AI research tools. It is based in Burnaby, British Columbia.
In November 2025 Clio completed a $1 billion acquisition of vLex and raised $500 million in a Series G led by New Enterprise Associates at a $5 billion valuation. It also has a $350 million debt facility from Blackstone and Blue Owl.
