Joyso Inc. (Headquarters: TOYOCHO SH Bldg. 7F, 4-10-4 Toyocho, Koto-ku, Tokyo; President: Yasutaka Shinomiya; hereinafter "Joyso"), which develops fixed-price on-site development for kintone, will officially launch "Skill39 (Skill Thank You)," a service that fully utilizes generative AI to continuously improve solutions for its own business challenges and enable site-led updates, on June 30, 2026 (Tue.). On the same day, we will begin accepting full contracts for general companies and 60-minute free individual consultation sessions. About Skill39 ■ Background to the Official Launch of Skill39 Following the preliminary announcement in May 2026, after verifying the operation of AI agents using generative AI in actual business environments with monitor companies, we are now widely launching the service for general companies. According to the "Digital Transformation Survey 2026" (DX Survey 2026) published by the Ministry of Economy, Trade and Industry and the Information-technology Promotion Agency (IPA) on June 5, 2026, many companies are making progress in digital utilization, including generative AI. However, among the questions regarding AI, the overall average score for "Cultivating and Securing Digital Talent" was the lowest at 61.9%. Even among DX Brand companies, which are evaluated as advanced in DX, the proportion of companies that responded best to "Securing talent to support DX promotion based on trends in the latest technologies such as generative AI" was relatively small. While the development of tools is progressing, securing the personnel to operate them remains a common hurdle regardless of industry or scale. Skill39 clearly states "self-sufficiency is the ultimate goal" in addressing this challenge. Instead of continuously procuring external specialized personnel, we provide a state where the site can independently continue improvements by enabling existing on-site staff to collaborate with AI, thereby breaking away from vendor dependence. ■ Service Ov
