What We Do

At Hoshii, we are building the Interaction Relationship Management (IRM) system, a platform that turns customer communication (emails, phone calls, etc.) into actionable ERP and CRM intents in one click. In an industry that faces a very intense labor shortage, where millions are stuck doing repetitive work, Hoshii’s IRM offers a co-pilot that handles tedious chores like processing unstructured data, responding to customer inquiries, and entering data into ERP systems.

How about you join us and build the next billion-dollar company? Exciting, right?! 😎
