WDTT, the operator of the AI-powered Japanese senior care service Minnanocare, has secured seed investment from Mashup Ventures and Digital Healthcare Partners (DHP).  

Minnanocare is an AI-driven total senior care solution that enhances communication and task management between families, caregivers, and nursing centers. By analyzing interview data and incorporating Japan’s complex long-term care insurance system, the platform automatically generates care plans. It also optimizes caregiver matching and digitizes nursing records, transforming the traditionally analog-based nursing care industry.  

WDTT was founded by Seokjun Lim, who was inspired to create the service after experiencing firsthand the challenges of family caregiving. Lim has extensive experience leading digital services for the Japanese market at global IT companies such as LINE and Salesforce. Co-founder Jiyoung Son also brings deep expertise in the Japanese market, having worked closely with Lim for years at LINE’s Japan headquarters.  

Focusing on Japan, where the long-term care insurance system is similar to Korea’s but aging is progressing much earlier, WDTT is set to conduct a PoC (Proof of Concept) with local facilities in April. The company plans to expand partnerships in the Shinjuku and Setagaya areas later this year.  

Seokjun Lim, CEO of WDTT, stated, “I have long been interested in the senior care industry, even obtaining a caregiver certification myself. I founded this company to tackle structural challenges in the sector through technology. Our ultimate goal is to create a structured environment where senior care is seamless and fulfilling for everyone.”  

In Sang-hyuk, partner at Mashup Ventures, which led the investment, commented, “Japan’s senior care market is growing rapidly due to accelerating aging, yet much of the industry still relies on analog systems, presenting significant market opportunities. We were particularly impressed by the founders’ deep experience in both B2C and B2B business in Japan, as well as their strong ability to enter and navigate the local market. This convinced us to move forward with the investment.”
