LegalOn Technologies, a leader in AI-driven contract review software, has successfully raised $50 million in a Series E funding round. This investment, led by Goldman Sachs’ growth equity fund with participation from existing investor World Innovation Lab (WiL), as well as new investors Mori Hamada & Matsumoto, Mizuho Bank, and Shoko Chukin Bank, aims to accelerate the development of AI agent tools and expand the company’s presence in the U.S. and U.K. markets.
Founded in 2017 by former corporate lawyers Nozomu Tsunoda and Masataka Ogasawara, LegalOn Technologies has rapidly become a prominent player in the legal tech industry. The company’s flagship product, LegalOn Review, utilizes artificial intelligence to streamline the contract review process by identifying potential risks and suggesting edits based on playbooks crafted by experienced attorneys. This approach has led to a significant reduction in review times—up to 85%—while enhancing the accuracy and quality of legal assessments.
The recent funding will be instrumental in advancing LegalOn’s AI capabilities, particularly in the development of AI agent tools designed to automate tasks surrounding the contract review process. These tools aim to address time-consuming activities such as organizing legal requests and managing contracts, thereby allowing legal teams to focus on more strategic initiatives.
LegalOn’s commitment to integrating AI with expert legal content distinguishes it from other legal tech solutions. By grounding its AI models in attorney-drafted materials, the company ensures that its contract reviews align with real-world legal standards, providing outputs that are both accurate and practical for legal professionals.
The company’s growth trajectory has been impressive. As of April 2025, LegalOn serves over 7,000 customers globally, including small legal teams and Fortune 500 companies across the United States, Europe, and Asia. This milestone reflects the increasing demand for AI-driven legal technology that offers both efficiency and precision.
To support its expanding customer base, LegalOn has been scaling its team and infrastructure. The company now employs over 600 professionals across the United States and Japan, including AI engineers, attorneys, software developers, and customer success managers. This diverse team is dedicated to advancing AI for contract review by combining deep legal expertise with generative AI, natural language processing, and machine learning.

The legal tech industry has witnessed significant investments in recent years, with companies like ContractPodAi raising $115 million in growth funding led by SoftBank Vision Fund 2 to shape the digital transformation of the legal industry. Similarly, LegalOn’s recent funding underscores the growing confidence in AI-driven solutions to address the complexities of legal workflows.
As LegalOn continues to innovate and expand, its focus remains on providing legal professionals with tools that not only enhance efficiency but also uphold the highest standards of legal accuracy and reliability.
