Turns the data collected from wearable devices into insights
About Tech Doctor
Established in June 2019, Tech Doctor is a Tokyo-based company operating at the intersection of healthcare and technology. The firm focuses on transforming daily data from wearable devices into actionable medical insights, a field it refers to as "data-based medicine". The company's core offering is its 'SelfBase' platform, which integrates, visualizes, and analyzes continuous, long-term data from various wearables and medical equipment. This platform is designed to assist in the development of digital biomarkers—objective indicators derived from digital devices that show disease presence or treatment effects.
The business model targets several client types within the healthcare ecosystem. For the food industry, SelfBase is used to verify and quantify the effectiveness of new or existing products for marketing purposes. In the realm of clinical research, the company provides comprehensive support, from study design and device procurement to data analysis from a medical perspective. This includes collaboration with clinical research organizations and offering supervisory support from academic experts. Tech Doctor's services are positioned to support decentralized clinical trials (DCT) and the broader adoption of online medical care. Since its founding, the company has secured $13.1 million in funding through multiple rounds, including a Seed Round in May 2021 and a Series A in June 2022, backed by investors such as JAFCO Group, Daiwa Corporate Investment, and Ono Digital Health Investment.
The leadership team includes President Kazumichi Minato and advisors with deep medical expertise, such as Dr. Mio Shinohara and Professor Manabu Minami. Dr. Shinohara has a three-decade career in veterinary medicine, holding a PhD in molecular oncology and specializing in integrating conventional treatments with holistic approaches like nutrition and herbal medicine. Professor Manabu Minami is a distinguished radiologist with extensive experience in oncologic and systemic diseases, having started his residency in 1983 and holding a professorship at the University of Tsukuba since 2004.
