Second Heart Inc. raised a Seed round extension from Toyama Co-Accel Fund, operated by Relic Inc. The Japanese healthtech company builds a preventive care platform for diabetic foot health. It did not disclose the round size.
Use of funds
The new capital will support four priorities. Second Heart will build medical institution partnerships in the Hokuriku region. It also plans to upgrade Steplife, start joint research, and strengthen its team.
Diabetic foot risks
Diabetic foot lesions can lead to lower limb amputation. Worldwide, one amputation occurs about every 20 seconds. More than 50% of patients die within five years after amputation.
Foot care tools
Steplife is a cloud platform for remote foot checks. Patients photograph and record their foot condition at home for medical staff to review. A digital tuning fork screens for peripheral nerve damage in about 30 seconds.
Second Heart plans to create a regional flow that connects patients to care when needed. It has a joint research agreement with Kyoto University from November 2025. The company has also tested its approach with Malaysia's PERKESO and built academic ties with Universiti Putra Malaysia.
