LegalOn Technologies is a global legal AI company that combines advanced artificial intelligence expertise with deep knowledge of law and contracts.

Founded in 2017, the company has been dedicated to building AI-powered legal services that enable legal and business teams to operate more efficiently and with greater confidence.

LegalOn develops solutions that support faster and more assured decision-making for legal and corporate teams. Backed by over $200 million in funding—including a $50 million Series E round—the company has seen rapid international growth. In 2022, LegalOn established its U.S. headquarters to drive global expansion, and in 2025, it launched CorporateOn, an AI Counsel product designed for the broader needs of corporate teams in Japan.

The company’s flagship product, LegalOn: World-Leading Legal AI, offers scalable support for contract review, drafting, and risk analysis. It is available in Japan, the U.S., and the U.K., serving professionals in some of the world’s most complex legal environments.

In 2025, LegalOn entered a strategic collaboration with OpenAI to co-develop next-generation legal AI agents. This partnership combines OpenAI’s state-of-the-art models with LegalOn’s legal domain expertise and proprietary datasets, resulting in tools that are faster, smarter, and developed with expert human oversight at their core.
