Co-presentation with Mizuho Financial Group Digital Strategy Department at 'Financial AI Conference 2026'

Information Strategy Technology Co., Ltd. (the 'Company') announces that it co-presented with the Digital Strategy Department of Mizuho Financial Group, Inc. at the 'Financial AI Conference 2026' held on May 21, 2026.

In this session, the company proposed organizational structures essential for continuously transforming technological evolution into business value without slowing down, citing the implementation of the meeting minutes automation app 'Menkikun'—part of the enterprise AI foundation 'Wiz Base' and used by 8,000 people monthly.

Background and Purpose In modern corporate management, fostering an organizational culture that turns change into a competitive advantage is essential. Mizuho Financial Group's Digital Strategy Department built a 200-person AI promotion organization in just two and a half years to respond to these changes. As a co-creation partner responsible for building that organization and implementing technologies including AI, the Company has supported development as a 'Zero Distance' one-team, removing barriers between enterprises. The presentation detailed organizational strategies for rapidly incorporating evolving technologies and accelerating trial-and-error, as well as the role played by the Company's '0th DX' support.

The core of this initiative is building an organizational structure where the client's business department, engineering department, and the Company's engineers work as one, transcending physical and psychological barriers based on the '0th DX (DX In-house Support)' model. This robust agile structure, which eliminates the boundaries of traditional client-vendor relationships and functions as a single team, is the essential foundation for quickly introducing fast-evolving generative AI technology to the field and verifying its efficacy. Under this co-creation system, efficiency verification is progressing in two areas:

1. 'Efficiency in Customer Operations' The introduction of the generative AI-powered meeting minutes automation app 'Menkikun' has brought dramatic changes to field operations. This app automates everything from transcribing meeting audio to formatting it into specific templates. Currently, 8,000 employees are active monthly users. By enabling the creation of high-precision drafts with the push of a button, it has eliminated the work of 'writing meeting minutes,' allowing bank employees to focus on higher value-added tasks such as customer interaction and strategy planning.

2. 'Efficiency in Development Processes' To standardize development flows and ensure consistent quality in large-scale development environments, the Company utilizes custom extensions that give generative AI specific professional skills and the ability to link with external tools. This enables high-quality, consistent output based on defined standard processes even in projects with many participating engineers. Furthermore, by combining this with 'Agentic Search' (autonomous search), the Company has established an advanced implementation flow that accurately analyzes vast existing documents and specifications and reflects them directly in the source code. This eliminates errors caused by human interpretation and minimizes rework from design to coding, resulting in stable development quality and shortened lead times.
