Clio hits $500M ARR as legal tech AI competition heats up

Canada-based legal tech company Clio has reached $500 million in annual recurring revenue (ARR). The company’s revenue growth accelerated after it integrated artificial intelligence into its offering in 2023. This milestone follows a period of growth for the firm, which had surpassed $200 million in ARR in mid-2024.

This revenue acceleration is reflected across the broader legal tech sector, where multiple players are reporting growth. Competitor Harvey reached $190 million in ARR by the end of 2025, according to Winston Weinberg, the company’s co-founder and CEO. Meanwhile, rival firm Legora announced last month that it reached $100 million in ARR 18 months after launching its platform. The rise of these platforms highlights the demand for AI-driven legal tools.

The legal industry is seen as a natural fit for Large Language Models (LLMs). Newton noted that LLMs are highly effective for coding because of the vast repository of existing code available for training, adding that the analogy to the legal field is clear. “Tech companies and lawyers alike are recognizing what a huge amount of upside there is for legal with LLMs,” said Jack Newton, co-founder and CEO of Clio. However, the market is experiencing a shift as AI model providers expand their offerings. Earlier this week, Anthropic announced new legal-specific features, expanding its Claude for Legal tool which made its debut earlier this year. Because legal tech firms like Harvey and Legora rely on Claude as a core model, Anthropic’s expansion means a key supplier is now acting as a competitor.

To secure its market position, Canada-based Clio is deploying its capital. The company was valued at $5 billion when it raised a $500 million Series G funding round last November. While Clio provides law firms with tools for time-tracking, invoicing, and payments, it is also expanding its capabilities. Last year, Clio acquired the data intelligence platform vLex for $1 billion. This acquisition allows lawyers to use Clio’s AI tools for research, bolstering the company’s position in the market.

Why it matters

Clio’s revenue growth underscores the potential for AI in legal tech, but the sector faces a complex future as AI model providers like Anthropic pivot from being suppliers to direct competitors.
