GRAND establishes a foundation to automatically build a tenant corporate master with AI, visualizing more than 28,000 tenant companies across 1,700 buildings nationwide at the corporate level

▤ Summary

GRAND has upgraded its AI-based system for automatically building a tenant corporate master across its office-building ad network. The company now cross-checks Japan’s corporate number API with a corporate database to identify tenant companies at the corporate level and reduce misidentification. This gives advertisers and agencies a clearer view of which headquarters or branch offices will receive their ads before they buy. The platform covers 1,700 buildings and more than 28,000 tenant companies, including 1,620 listed companies. GRAND positions this data foundation as a core capability for improving target-list advertising accuracy and keeping reach data current.
