-------------【About the company】-------------

The company has historically supported the operational efficiency of pharmacies by providing various solutions, primarily centered on its cloud-based medical history system. These solutions include a management tool that visualizes pharmacist-specific performance and patient revisit rates in real-time, and an application for patients that enables follow-up based on individual prescriptions.

In August 2022, the number of pharmacy users of the cloud medical history system surpassed 7,000 nationwide, and the service has grown to be utilized by over 15% of the pharmacy industry's top market share within six years of its release. With a funding round of ¥7.6 billion in January 2023, and an additional ¥1.8 billion in March, the company is poised for further significant business growth.

For new ventures, the company is also addressing contributions to stable supply by developing an inventory management system that supports inventory optimization through AI demand forecasting and a pharmaceutical secondary distribution service that supports inter-store transfers and pharmaceutical waste reduction.

Furthermore, by utilizing the patient data accumulated through its services and direct patient touchpoints, the company aims to encourage behavioral changes among patients and healthcare professionals. Through these efforts, they intend to make the entire Japanese healthcare experience—including the pharmaceutical industry and the medical system, not just pharmacies—more adaptable and resilient.
