Dentsu Soken Inc. (Headquarters: Minato-ku, Tokyo; Representative Director and President: Hirohisa Iwamoto; hereinafter "Dentsu Soken"), a company that realizes the evolution of companies and society through technology, announced that its "AI Agent Construction Support Service" has been adopted by Aoyama Zaisan Networks Inc. (Headquarters: Minato-ku, Tokyo; Representative Director and President: Masazumi Hasumi; hereinafter "Aoyama Zaisan Networks"), and that the development of AI agents has officially commenced. This service utilizes "Microsoft Foundry" provided by Microsoft to offer end-to-end support for AI agents, from PoC (Proof of Concept) to mass production and operation.

■ Background

Aoyama Zaisan Networks primarily operates in comprehensive asset consulting, which requires highly individualized and sophisticated judgment in areas such as inheritance, business succession, real estate, and asset management. In these fields, challenges include the need for "customized proposals based on the unique circumstances and backgrounds of each client" and "rapid response to constantly changing specialized knowledge, such as tax law revisions and real estate market trends," leading to heavy workloads for individual consultants and difficulties in the early independence of junior consultants.

Under these circumstances, the company aims to "build new working styles through co-creation between consultants and AI" as one of its intellectual property strategies in its medium-term management plan, promoting the utilization of DX and AI. The current AI agent construction is part of these concrete initiatives, and Dentsu Soken was selected as a collaborative partner.

It integrates with "Microsoft 365" and "Microsoft Azure (hereinafter "Azure")" to create an environment where AI agents provide 24-hour support for tasks such as interviewing, research, document creation, and knowledge retrieval. By combining specialized and general-purpose agents according to business characteristics, it achieves improved productivity for consultants and employees, and standardization of work quality. It provides end-to-end support from PoC to full-scale operation, improvement, and in-house development.

This was a key factor in its adoption.
