iYell Co., Ltd. (Headquarters: Meguro-ku, Tokyo; CEO: Mitsuhiro Kubota; hereinafter "iYell") announced today that on May 12, 2026, its 10th anniversary, it will launch "Founder's AI," a proprietary generative AI tool trained on the management philosophy and thought processes of its founder, Mitsuhiro Kubota. The tool will be fully implemented across the group.

《Background》

From 3 to 300 employees: "Synchronizing Culture" follows the 250,000-character "Founder's Legacy" management philosophy guide.

Founded in 2016 with just three employees, iYell has since grown rapidly to approximately 300 employees group-wide (269 as of the end of April 2026). As the company expanded its operations to various locations across Japan, including Tochigi, Saitama, Osaka, Fukuoka, Nagasaki, and Okinawa, and extended its network overseas (Vietnam), opportunities for direct dialogue between Kubota and employees diminished, creating a "physical distance barrier" in conveying the company's vision.

iYell's greatest strengths lie in its unique "culture" cultivated since its founding and its shared value system, its "Values." As the organization expanded and the physical distance from Kubota increased, it became crucial for the next decade to ensure that employees worldwide could access the founder's mindset at any time and make autonomous decisions without diluting the company's passion.

Following the release of the 250,000-character management philosophy guide, "Founder's Legacy," iYell is embarking on a new challenge to implement these universal ideas into daily communication through cutting-edge technology. To embody the value of "playfulness," "Founder's AI" was developed as a futuristic conversational tool that allows employees to interact with the founder's philosophy anytime, anywhere, as if the founder were present, even when Kubota is unavailable.

《Overview and Features of Founder's AI》

"Founder's AI" is a culture dissemination support tool that utilizes GoogleTM's AI notebook "NotebookLM" and has been trained on iYell's extensive proprietary data.

1. Complete synchronization of Kubota's thoughts: The AI has comprehensively learned from "Founder's Legacy," a 250,000-character guide for practicing management philosophy, as well as morning assembly messages, internal newsletters, and training materials from the past 10 years.

2. From business to private life: Employees can casually consult the AI anytime for advice on management decisions, mental well-being, and even personal matters such as "how to spend holidays," providing an opportunity to casually learn about Kubota's values.

3. Embodiment of "playfulness": An SF-style icon modeled after Kubota has been created to offer a user experience that excites employees and encourages repeated use.

*This tool operates in a secure environment where internal data is not used for external AI training.

《Future Outlook》

Since its founding, iYell has fostered a culture of supporting and bringing happiness to everyone involved. With the introduction of "Founder's AI," iYell aims to strengthen an environment where each employee can grow in their own way, without diluting this "spirit of support," regardless of how much the organization expands. Beyond the realm of home loans, by combining technology with its unique culture, iYell will contribute to realizing a society where chains of happiness spread throughout the world.
