Artificial intelligence is transforming many industries, but one area seeing rapid growth is legal technology. Companies are leveraging large language models (LLMs) to automate tasks like document review and drafting, saving time and reducing costs. This shift is fueling impressive revenue gains for legal tech firms, with some surpassing hundreds of millions of dollars annually.

Clio’s Rapid Growth in Legal AI

Clio, a Canadian company that offers law practice management software, has become a standout in this space. After integrating AI features in 2023, the company saw its revenue skyrocket. By mid-2024, Clio had already exceeded $200 million in annual recurring revenue (ARR) and doubled that number by late last year. Most recently, they announced hitting a $500 million ARR milestone.

CEO Jack Newton believes that LLMs are a perfect fit for legal work because of the vast amount of text-based data law firms handle. Contracts, agreements, and legal documents provide a rich training ground for AI models. Newton sees enormous potential in applying AI to legal services, comparing it to how AI excels at coding due to the abundance of source code available for training.

Other Legal Tech Companies Achieving Success

Clio isn’t alone in this growth. Harvey, a four-year-old startup offering AI solutions for law firms, reported reaching $190 million in ARR by the end of 2025. Its main competitor, Legora, announced hitting $100 million ARR just 18 months after launching. These companies rely on LLMs like Claude, developed by AI provider Anthropic, which has also expanded its legal-specific features recently.

This creates an interesting dynamic, as some of the leading AI models are now also competitors to the legal tech firms that use them. Despite this, the overall outlook remains optimistic. Investors see huge opportunities, especially since Clio was valued at $5 billion after raising $500 million last November. The company’s recent acquisition of a data platform now allows its AI to be used for legal research, expanding its capabilities further.

Overall, the legal AI market is gaining momentum, driven by the proven ability of LLMs to automate tedious tasks and improve efficiency. As AI continues to evolve, more law firms and legal tech startups are expected to adopt these tools, potentially revolutionizing how legal services are delivered.
