Joyso Launches "Skill39," a Business Improvement AI Companion Service

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 Overview

Skill39 is a business improvement companion service that consistently handles everything from AI (Claude) interviewing business operations, extracting issues, proposing solutions, to developing your company's dedicated "Business Improvement Skills (Manuals for AI)."

The biggest feature is its unique mechanism of "AI creates AI." Since generative AI automatically creates dedicated skills based on your company's business content, there is no need to give instructions from scratch each time, preventing malfunctions due to inconsistencies in instructions.

The know-how accumulated by Joyso over 15 years and more than 1,750 business improvement projects has been packaged for generative AI, and it is designed to be usable even by on-site staff who are not familiar with AI. By having Joyso, who is well-versed in business improvement, provide support, we will ensure that on-site staff learn how to instruct AI effectively for their company's business improvement in a practical manner.

For companies using or considering kintone, we also offer an option for a dedicated development environment where generative AI handles kintone customization development and operational maintenance.

Main Use Cases

1. Teach the AI your company's "way of doing things" and standardize business quality

"Our quotations should be in this order," "Contacting customers should be in this tone"—Business rules that were previously in the heads of担当者 (person in charge) are verbalized as dedicated manuals (skills) taught to AI. Once built, the AI will perform tasks with the same quality repeatedly. This reduces the burden of handover and makes new members immediately effective.

2. Reflect "I want to change this" directly into kintone (for kintone users)

"I want to add a button to this screen," "I want to change this approval flow"—System modifications were previously outsourced tasks. With Skill39,担当者 can simply communicate in their own words to the AI, and customized code tailored to your company's kintone environment will be generated and applied. This completes the process from request to implementation without programming.

3. Utilize know-how buried in comment sections and internal communications for future negotiations

Records of customer interactions, exchanges in internal spaces—AI will search and summarize textual data accumulated in kintone across the board, answering questions such as "What was the background of the previous proposal to this customer?" or "How was a similar case handled?" Qualitative data that was previously buried will become assets supporting on-site decision-making.
