We are a global legal AI company with advanced technological capabilities in AI and specialized knowledge in law and contracts. Since our founding in 2017, we have focused on developing legal AI services powered by artificial intelligence, raising a total of approximately ¥28.6 billion in funding, establishing a group company in the United States in 2022 to accelerate our global expansion, and continuing to grow at a remarkable pace. Currently, we offer our flagship product, "LegalOn: World Leading Legal AI," which has been released not only in Japan but also in the United States and United Kingdom. We are also boldly expanding into multiple new business areas, and in January 2025, we extended our business domain to cover all corporate functions with the release of AI Counsel "CorporateOn." Our products feature AI-powered capabilities including machine learning algorithms in natural language processing, large language models (LLMs), as well as our "Legal Document Graph" that systematically organizes accumulated information, and AI agents that autonomously plan and execute tasks.
