Market position

estie describes itself as operating a large-scale commercial real estate data analysis platform in Japan and reported an adoption rate above 70% among major real estate developers and J-REITs at the time of its Series B.

Technology

Real estate developers, institutional investors, J-REITs and asset managers, real estate brokerage and leasing companies, and financial institutions such as banks and trust banks.

Geography

History

Founded in December 2018, estie initially focused on office leasing, offering an AI-driven office matching service and the estie pro platform connecting owners, managers and brokers. It raised roughly 250 million yen in a pre-Series A in July 2020 from Globis Capital Partners and UTEC, followed by about 1 billion yen in a Series A in January 2022. Through 2020-2021 it formed business partnerships with subsclife, Venture Property, Vis, Monooc, Japan Commercial Real Estate Guarantee and Clas. It entered a capital and business alliance with the Development Bank of Japan in October 2023, partnered with CRE on logistics market reports in June 2024, and closed a 2.8 billion yen Series B in October 2024. In January 2025 it announced capital and business alliances with Mitsubishi UFJ Trust and Banking, Sumitomo Mitsui Trust Bank and Zenrin, and in April 2026 with Norinchukin Bank [3][5][6].

Risks & controversies

Stated uses of Series B proceeds include M&A, partly financed with debt from financial institutions, which carries integration and leverage execution risk; investors also noted volatility in the broader SaaS market [5].
