Leveraging 'GRAND AI' for Data-Driven Advertising: Mitsubishi Estate Group's Office Media 'GRAND' Enhances Reach Visualization

GRAND Inc. (Headquarters: Shinjuku-ku, Tokyo; President: Hitoshi Sakaue / Mitsubishi Estate Group), operator of the office building advertising media 'GRAND,' has designated 2026 as the 'First Year of AI Utilization' and is fully implementing AI for advertising reach visualization, centered on its suite of cross-departmental AI tools, 'GRAND AI.'

While GRAND is a medium that broadcasts across building signage, its core strength has been a target-list-based operation that discloses tenant companies in advance, allowing clients to understand 'which companies and business people are in which buildings and where ads will reach' before placement. By utilizing AI to organize and cross-reference this unique tenant data, GRAND is building a system that allows advertisers to more accurately grasp 'which major companies and demographic layers ads will reach.'

Background: From 'Wide Coverage' to 'Targeted Reach' with AI

GRAND broadcasts widely to office areas in the buildings it serves. Its value lies in the ability to visualize 'which companies and business people ads reach.' GRAND has differentiated itself by sharing tenant lists in advance, allowing clients to place ads with knowledge of the destination. This initiative further advances this visualization using AI.

Key Point: Moving beyond 'set and forget,' we visualize the audience both before and after ad placement.

Initiatives: Enhancing 'Destination Identification' with Tenant Data x AI

GRAND is applying AI to the organization and cross-reference process of its proprietary tenant company data to increase the accuracy and speed of reach visualization.

Areas of AI implementation

- Organization of tenant data: Streamlining the structuring, matching, and updating of tenant company information (such as corporate registration numbers) per building using AI. - Visualization of reach: Improving the accuracy of grasping and presenting reaching companies, number of companies, industries, and demographics before ad placement. - Understanding demographics: Supporting the visualization of reach by industry (Finance, SaaS, Manufacturing, etc.) and decision-maker segments. - Streamlining competition and standards: Organizing the judgment process for ad feasibility and competitor exclusion to speed up proposals.

Through this, GRAND aims to elevate operations, enabling advertisers and agencies to make placement decisions with a more accurate understanding of 'which major companies and how many will be reached.'

*This initiative is being advanced in stages, with the scope and service formats expected to expand sequentially.

Corporate Policy: 2026 as the 'First Year of AI Utilization'

GRAND has positioned 2026 as a phase to fully implement AI across all processes of reach visualization, effect verification, and operational proposals. By utilizing the 'GRAND AI' tool suite to support internal tasks and streamline routine work, the company intends to create a system where human talent is focused solely on providing optimal proposals for each individual advertiser. The proprietary primary data GRAND holds, 'tenant company data of served buildings,' becomes an asset of higher value when combined with AI. By honing this with internal data x AI, the company clarifies 'which company and who is being reached,' a resolution difficult to achieve with AI search or standard digital advertising.

Values targeted by this initiative

- Improved reach visualization: More accurate grasp of reaching companies, industries, and demographics before placement. - Improved proposal speed: Streamlined grasping and matching of reach to accelerate quotes and plan presentations. - End-to-end effect verification: Free inclusion of Brand Lift Surveys (BLS) in all plans to verify awareness and behavioral change numerically after placement.

99% of GRAND's viewers are business people, and many of the client companies are large enterprises. The medium's characteristic of 'knowing beforehand who it reaches' is further polished through AI utilization.
