Clio Hits the $500 Million Milestone as Legal Tech Booms with AI

When it comes to artificial intelligence (AI), its applications span every industry, from healthcare to customer support. However, one area that has seen an explosive rise in both popularity and profitability is code writing. This trend isn't just theoretical; it's driving significant growth for companies like Clio, a Canadian legal tech firm.

Jack Newton, the co-founder and CEO of Clio, believes that legal technology (legal tech) could be next in line to benefit from large language models (LLMs). As Clio approaches its $500 million annual recurring revenue (ARR), it's clear why Newton is bullish on this space.

Coinciding with these impressive numbers, Clio saw a significant uptick in revenue growth after integrating AI into its offerings. By mid-2024, the company had already surpassed $200 million in ARR and doubled that figure by late 2025. The latest announcement marks an ARR of $500 million for Clio.

Newton explains, 'LLMs are incredibly effective for coding because they have access to a vast repository of existing code. Similarly, the legal field is rich with contracts and agreements, offering plenty of text-based data for AI models to learn from.' This wealth of data makes legal tech companies like Clio well-positioned to capitalize on LLMs.

The success isn't limited to Clio; other players in this space are experiencing similar growth. Harvey, a four-year-old legal tech company, reported an ARR of $190 million by the end of 2025. Its main rival, Legora, recently announced reaching $100 million in ARR just 18 months after launching its platform.

These numbers reflect the growing recognition that LLMs can automate some of the most time-consuming tasks in legal work, such as document review and drafting. Both Harvey and Legora rely on Claude, a core model from Anthropic, adding an interesting dynamic to their relationship: key supplier, now also competitor.

For Newton, these developments are just early signs of broader potential within the legal AI market. Clio's own valuation of $5 billion during its latest series G funding in November 2024 further underlines this optimism. The company offers law firms time-tracking, invoicing, and payment tools, with recent acquisitions like data intelligence platform vLex allowing lawyers to leverage Clio’s AI for research purposes.
