Atomic Software

Japanese clinics that sell treatments directly to patients need bookings, charts, contracts and payments to line up, and medicalforce was written from scratch for that work. Its maker, Atomic Software of Shinagawa, Tokyo, was founded in November 2020 as Medicalforce and took its current name in February 2026, when it began selling software to other industries as well.

medicalforce in the clinic

medicalforce went on sale in March 2021. It records reservations, medical charts and payments in one system and has grown to cover CRM, advertising measurement and business analysis. The company says more than 800 clinics used it as of September 2026, across both self-pay and insurance practice, with a retention rate of 99.2% as of March 2026. The Hada no Aozora Clinic chain, supported by SBC Medical Group, runs it as its core and payment system.

AI notes and follow-ups

The AI features carry the name medicalforce intelligence. An AI voice chart that drafts records from consultation conversations entered early release in May 2026, and the company estimates heavy users save up to 36 hours of record-keeping a month. An AI chart summary and AI-drafted follow-up messages for patients after treatment followed in August.

The second product, Keibi Force, is an all-in-one system for security guard companies. The company holds ISO/IEC 27001:2022 certification and has a West Japan branch in Chuo-ku, Osaka, besides its Tokyo head office.
