About the company

We provide a photo sales service based on our vision of "creating a platform that enriches family communication".

Product 1: A photo sales service for nursery schools with more than 2,200 installed facilities and nearly 150,000 users in Japan. This service allows parents and families to view photos of children taken by childcare workers from their PCs, smartphones, and tablets, and to communicate with them. Photos taken by childcare staff are automatically sent to the server, where they are organized and shared using image recognition technology.

In-house Product 2: A service that uses technology to streamline and improve the nursery school napping check (checking the afternoon sleep of children at five-minute intervals). The service was launched with the hope that childcare workers would have more time to focus on the growth of the children.

We are looking forward to working with you to create a platform that enriches family communication, and to take on the challenge of building a smart preschool, a business with high social significance. We are actively looking for new colleagues who will take on the challenge of "enriching family communication around the world".
