Modernizing Real Estate

estie is a real estate tech startup that has its origins in the Economics department of The University of Tokyo. Although location strategy is one of the most important decisions that can affect a company’s competitiveness, both leasers and lessees are overwhelmed by complex administrative precedures and distracted from considering the more critical issues for their customers. To tackle this issue, estie built a platform that allows users to compare office rental properties listed by multiple real estate agents, and disclosing “e-rents”, which are considered reasonable based on AI algorithms.



estie founder Ei Hirai developed and implemented statistical analysis methods for real estate performance during his time engaging in overseas real estate investment and office leasing sales at Mitsubishi Real Estate. Hence, he started estie to solve the industry problem where even professionals have not been making objective decisions based on sufficient logical evidence, while tenants were forced to make decisions with insufficient information in 2018.


The estie team possesses deep real estate industry knowledge, which they leverage on to build algorithms for estimating rents and other real estate quantitative indicators. These algorithms are hard to imitate as they are based on one of the largest integrated databases in the market.
