Our Team.

Training and retaining foreign care workers made simple.

Ryoji Nagai

Representative

After five years as a software engineer at Itochu Techno-Solutions Corporation (CTC) and DMM.com LLC, I founded my own company to create solutions for the caregiving field. By listening closely to facilities’ needs, we build products that simplify training, improve communication with foreign staff, and strengthen trust between caregivers and management.

Newton Nandy

Product Manager

With over two years of caregiving experience in Japan, a National Caregiver Certification, and JLPT N1, I understand both care work realities and training challenges. Combining this with my business background, I develop tech and education solutions that cut onboarding costs of foreign caregivers, boost retention, and enhance safety and communication for care facilities.

After finishing my studies, I honed my skills as a software developer, building practical solutions. I also nurture a strong interest in technology innovation and AI, exploring future possibilities.
