Zest Co., Ltd. (Head office: Shinjuku-ku, Tokyo; Representative Director and CEO: Junnosuke Isshiki), a provider of schedule optimization and management support cloud for visiting nursing, elderly care, medical clinics, and facilities, has fully launched research and development for its "AI Agent" function, which leverages generative AI to autonomously solve business management challenges. Aiming to evolve from a "tool providing functions" to a "partner inheriting management know-how," a test release is planned within 2026.
Zest will powerfully support sustainable and sound business operations in the elderly care and medical fields, based on its contribution to improving AI literacy across the entire industry, beyond the scope of its own products.
■ Background: Limitations of General SaaS and Management Challenges in the Elderly Care and Medical Industries
Currently, while various SaaS products are widespread, over-functionalization and commoditization are advancing, leading to criticisms of "SaaS limitations (SaaS Is Dying?)" such as "introduced but unable to utilize fully." Particularly in industries like visiting nursing and elderly care, sophisticated management decisions are constantly required, including complex schedule management, talent acquisition, and profitability improvement. Many managers and administrators are cultivating know-how through several years of trial and error and hardship to address complex issues based on their on-site experience.
Zest believes that it is necessary to evolve from conventional general SaaS to "AI-native SaaS" specialized for the elderly care and medical industries, going a step further to address these industry-specific challenges.
■ Initiatives to Promote AI Utilization Across the Entire Industry, Not Just for Our Own Products
Zest has always gone beyond merely selling and providing its own tools, working to correctly return the advancements of AI technology to the elderly care and medical industries. On its corporate website, the "ZEST AI TECH Lab" widely publishes practical methods for utilizing external generative AI to aid operations in visiting nursing and elderly care. While the spread of generative AI makes it easy to create simple tools, operations lacking security can directly lead to risks of leakage of sensitive personal information and patient data. Therefore, through contributions to specialized magazines and other means, Zest actively engages in enlightenment activities to help on-site staff safely utilize the latest technologies, including essential security measures and information management precautions necessary when introducing generative AI.
This daily research and deep insight into "improving AI literacy and safe utilization across the entire industry" form the solid foundation for Zest's unique "AI Agent" concept, which is being announced this time.
■ ZEST's Vision for "AI Agent"
The "AI Agent" that Zest is developing is not just a tool that performs instructed tasks; it is a partner that makes various proposals autonomously using generative AI, functioning as a right-hand assistant on-site. In 2026, Zest is proceeding with the development and implementation of the following functions:
* Confirmation and provisional reservation of available slots when accepting new users
To quickly respond to inquiries about the feasibility of accepting new users, the AI will match necessary information and make acceptance decisions simply by inputting conditions such as desired date/time, area, and service content. Furthermore, as an advanced form, Zest is considering providing an AI Agent that automatically performs provisional reservations within the system if the contract certainty is judged to be high.
* Integration with the Management Dashboard
The AI will regularly monitor and analyze management data from ZEST BOARD, delivering an automatic summary of significant management changes, such as major differences from the previous week. Furthermore, in addition to presenting concrete improvement actions based on industry insights for underlying issues, Zest is considering a function where the AI autonomously detects situations requiring action, such as operating rates falling below a certain level, and either executes improvement actions within the system or immediately proposes them to managers. This will create an environment where even inexperienced managers can make decisions similar to those of seasoned experts.
* Conversational AI for Management Support
For busy administrators, Zest is proceeding with research and development of a voice UI that can be utilized during travel for visiting tasks. This is envisioned for uses such as reading out ZEST BOARD management summaries and immediately responding to inquiries about specific metrics. Conversational AI will instantly provide concrete action plans, becoming a reliable partner that can be consulted about management concerns at any time.
■ Future Outlook: Aiming for Test Release Within This Year (2026)

Zest has already commenced research and development for implementing these AI Agent functions, building upon the high quality offered by its current products. Zest AI aims to inherit the management know-how gained from the "failures and hardships" experienced by numerous businesses.
