rYojbaba Announces the Launch of AI-Powered Worker Risk Intelligence Platform

FUKUOKA, Japan, Dec. 2, 2025 -- rYojbaba Co., Ltd. (Nasdaq: RYOJ) (“rYojbaba” or the “Company”), a Japanese labor consulting and health services company, announced the launch of an AI-powered Worker Risk Intelligence Platform designed to leverage and unify data across the Company’s Osteopathic Clinic, Free Labor Union, and Legal Services business.

The Worker Risk Intelligence Platform is powered by first-party data generated across the operations of rYojbaba’s Osteopathic Clinics, Free Labor Union, and Legal Services. Over the past three months, rYojbaba has formed strategic partnerships with organizations such as Guardian Girls International (GGI) and expanded its three core business services into international markets such as Cambodia, Indonesia, Philippines, Thailand, and Vietnam. As a result, the Company experienced a surge in international worker enrollments driven by the GGI partnership, a sharp increase in international collaboration with overseas organizations and embassies, and a large inflow of multilingual and multicultural labor data.

Each business contributes a distinctive set of data that fuels the platform:

Building on this enriched, globally sourced data ecosystem, rYojbaba’s Worker Risk Intelligence Platform transforms the raw data and delivers strategic intelligence and predictive analytics tailored to three distinct types of firms:

Having built up a robust network of Japanese corporations, insurance providers, and municipalities that benefit from rYojbaba’s services, the Company aims to target this network as the initial customer base to upsell the new platform. Additionally, recent international expansion and partnerships with global organizations, embassies, and municipalities further supports the Company’s strategy of targeting and onboarding trusted institutional partners to support scalable, efficient growth. The Company is actively in discussions with several organizations in Japan and internationally that have indicated strong interest in adopting the new platform. The pipeline includes institutions connected through the partnership with GGI, multiple embassies, and labor-related entities in Southeast Asia.

Company CEO Ryoji Baba commented: “In certain global markets, worker instability is rising due to ongoing geopolitical tensions, currency volatility, and declining psychological safety in workplaces. These conditions have created a global demand for a solution capable of visualizing risks across the workplace for corporations, insurance providers, and municipalities. rYojbaba’s corporate mission continues to revolve around creating a healthier workplace for employees while improving overall productivity for employers. We believe the Worker Risk Intelligence Platform aligns with our corporate mission by providing corporations, insurance providers, and municipalities actionable insight into workers’ overall physical and mental well-being. I am proud to say that rYojbaba has evolved from being solely a Japan-centric health and legal services provider to now an emerging global labor-intelligence company. The steps we have taken over the past three months have been intentional, and the development and launch of this new service could not have been achieved without our partnerships and international expansion.”
