Challenges mign Addresses

The real estate and construction industry, a cornerstone of Japan's economy, still retains many analog and complex business workflows. In particular, building confirmation, which is mandatory before constructing a building, and legal compliance checks, which involve deciphering vast numbers of ordinances, require extremely high expertise. Simultaneously, the industry faces severe challenges due to an aging workforce and labor shortages.

mign aims to overcome these extremely difficult industry challenges with AI agents. Since the release of the following product in August 2025, the number of companies adopting it commercially has been steadily increasing.
