We are a global leading company providing Professional AI — products that combine deep domain expertise with advanced AI.
Since our founding in 2017, we have focused on developing AI-powered legal technology, raising a total of approximately JPY 28.6 billion to date. In 2022, we established our U.S. entity, and in 2025, we accelerated our global expansion further through our first M&A, welcoming Germany-based Fides Technology into our group.
Our flagship product, LegalOn, is currently available in Japan, the United States, and the United Kingdom. In September 2025, just six and a half years after launch, LegalOn surpassed JPY 10 billion in ARR. Beyond legal, we are expanding into other highly specialized domains with products such as WorkOn, DealOn, and GovernOn, leveraging AI to support complex professional work.
Through our strategic partnership with OpenAI, we incorporate cutting-edge technologies such as AI agents into our product development. By delivering solutions that address a wide range of business challenges, we empower our customers to achieve better outcomes.
