About the Company
Representative & Developer
Ryotaro Ako
To help as many people as possible find relief from eczema
Programmer | Master of Engineering | Certified Public Accountant
Based on personal experience with three allergic conditions—eczema, asthma, and allergic rhinitis—the developer engaged in volunteer work with a patient advocacy group. After conducting interviews with eczema patients, receiving insights from pharmacist Akiko Ako, and guidance and supervision from a programmer, they developed this app independently.
After completing a Master’s degree in Science and Technology at Keio University Graduate School, he received his CPA certification. Following careers at Ernst & Young ShinNihon LLC and Renova, Inc., he founded Atopiyo LLC.
Background
Based on his own experience with eczema in childhood, Ryotaro Ako studied programming, conducted interviews with eczema patients, and received insights from pharmacist Akiko Ako, along with guidance and supervision from programmers, to develop the “Visual Eczema Care App – Atopiyo.”
Eczema causes persistent itching 24 hours a day, even during sleep, and since it affects visible areas of the body, it can also have a major impact on one’s quality of life, both mentally and physically.
This app aims to support people suffering from eczema by (1) helping them manage their symptoms on their own, and (2) creating a space where they can exchange information with others. It also seeks to promote early recovery.
Furthermore, in collaboration with pharmaceutical companies and medical institutions, the app aims to contribute to research, product development, and public awareness in the field of eczema.
