What Entrust does

Entrust Inc. (株式会社イントラスト) is a Tokyo-headquartered, publicly listed comprehensive guarantee services company operating in Japan. Founded in 2006 and listed on the Tokyo Stock Exchange (ticker 7191; Mothers in Dec 2016, First Section in Dec 2017, currently Standard Market), the company originated in rent debt guarantee and has expanded into three adjacent verticals: medical expense guarantee (product "Niji"/虹, launched 2015), nursing care expense guarantee ("Taiyo"/太陽, 2017), and child support guarantee (industry-first, Feb 2018).

The business operates two pillars: a guarantee business that acts as substitute corporate surety across rent, medical, care, and child support obligations, and a solution business (C&O Services, Doc-on SMS platform, Insurance Desk Service, Raku-Cre SMS credit card payment) that monetizes operational expertise built through the guarantee franchise. Core technology comprises a proprietary statistical rent guarantee screening model co-developed with Mitsubishi Research Institute (Patent No. 6333431), an SMS-based debt management contact system (Patent No. 6283070), and an SMS-based credit card payment mechanism (Patent No. 6431377). Underlying infrastructure uses NTT Communications for domestic SMS routing, cloud-based operational systems, and a proof-of-concept cloud AI service (MSYS Omnis) for call center optimization.

Entrust monetizes primarily through recurring guarantee fees paid by tenants/patients/residents and solution service fees paid by enterprise clients. Go-to-market is enterprise field sales targeting large and mid-tier real estate management companies, hospitals, and elderly care operators, supplemented by B2B2C channel partners (Daiwa House Group, Starts Group, ORIX, Sumitomo Realty), insurance co-development partners (Tokio Marine & Nichido, Mitsui Sumitomo Marine & Fire), and municipal government subsidy programs for child support. As of March 2018, Entrust served 94+ medical institutions and 142+ elderly care facility operators, with combined rent guarantee and solution contract growth averaging approximately 20% annually over the prior three years.
