What mediaid does

Mediaid (株式会社メディエイド) is a Tokyo-based IT firm founded in 2005 that builds and operates a cloud-based Personal Health Record (PHR) platform, primarily serving healthcare enterprises and patients in Japan. Its core product, LiNQ-CIRCLE, is a FHIR-compliant microservice platform hosted on AWS Japan that ingests data from connected medical devices (OMRON, A&D, Nipro, Terumo, Fitbit) and consumer health platforms (Apple HealthKit, Google Health Connect), and is integrated with Japan's government-issued Myna Portal. Around this core, Mediaid offers consumer apps (LiNQ-Palette, Shoku Palette, Karada Palette, Myna Palette), professional tools for pharmacists and dietitians (LiNQ-Pad, LiNQ-Touch), disease-specific patient support programs (e.g., CareDiary for Fabry disease, ハピるん for SLE), and a Pharmaceutical Database API launched in August 2025.

The company monetizes through enterprise contracts with pharmaceutical companies for patient support programs and PHR deployments, agreements with pharmacy chains, consumer-goods sponsorships (Nestlé Japan, Shideido), and an emerging API-licensing line. Pricing is quote-based and not publicly disclosed. Its revenue is structurally project-based on pharma PSP work supplemented by platform access fees, while consumer apps follow a freemium model. Compliance is a central operational pillar: ISO 27001 (2020), ISO 27017 (2023), ISO 9001 (2023), Privacy Mark (2007), a Medical Device Manufacturing License (2016), and alignment with Japan's three-ministry PHR information security guidelines.

Mediaid serves a diverse enterprise base including Takeda, Asahi Kasei Pharma, Maruho, Astellas, Sanofi, Viatris, Amicus Therapeutics, Craft and other pharmacy chains, Nestlé Japan, Shiseido, and the Japan Cancer Association. The company is privately held, bootstrapped, and small (1–10 employees), with leadership centered on founder-CEO Hiroshi Yajima (矢島弘士) and pharmacist COO Risa Yanai (柳井理沙). Recent strategic emphasis is on extending the platform from a PHR data backbone into modular APIs and adjacent wellness verticals, exemplified by the WellChaos fitness partnership (April 2025) and the Pharmaceutical Database API launch (August 2025).
