Clio, a Canadian law firm management software company, has reached $500 million in ARR, accelerating sharply after integrating AI in 2023. The legal tech sector is seeing broad AI-driven growth, with Harvey hitting $190M ARR and Legora reaching $100M ARR just 18 months after launch. Complicating the landscape, Anthropic — a key model provider for Harvey and Legora — has expanded its Claude for Legal product, making it both a supplier and competitor to legal AI startups. Clio, valued at $5 billion after a $500M Series G in late 2025, also completed a $1 billion acquisition of legal data platform vLex to bolster its AI research capabilities.
