LegalOn Technologies, a Tokyo-based legal tech firm, has secured $50 million in Series C funding to expand its AI-powered legal workflow solutions. The round, led by Goldman Sachs’ growth equity fund, also included World Innovation Lab, Mori Hamada & Matsumoto, Mizuho Bank, and Shoko Chukin Bank. The investment will help LegalOn develop advanced AI agents and strengthen its presence in the U.S. and U.K., where its business has quadrupled in the past year.
LegalOn specializes in AI-driven contract review software called Review, which flags risks and recommends edits based on attorney-crafted playbooks and each client’s legal standards. The company says its tool cuts review time by up to 85% while improving accuracy and consistency. Used by 7,000 organizations worldwide — including 25% of Japan’s publicly listed companies — LegalOn claims to be the market leader in its home country.
Founded in 2017 by former corporate lawyers Nozomu Tsunoda and Masataka Ogasawara, LegalOn has recently launched additional solutions like Matter Management to help legal teams organize requests, assign tasks, and collaborate across departments. The company also announced a technical partnership with OpenAI, granting it access to advanced language models to enhance its AI-powered legal agents.
Despite AI’s rapid adoption in legal tech, Global CEO Daniel Lewis says LegalOn’s strength lies in its foundation of attorney-developed legal content, which ensures precise, practical contract analysis out of the box. “Lawyers remain in the driver’s seat,” Lewis said, emphasizing AI as an enhancement rather than a replacement.
The new funding brings LegalOn’s total capital raised to over $200 million, with previous backers including SoftBank Vision Fund and JAFCO. As legal technology adoption accelerates globally, LegalOn aims to position itself as a leader in delivering AI tools that empower — rather than replace — legal professionals.
