Let’s create the future of pet experiences together!

Our Vision

By fostering a genuine emotional bond between robots and humans,
we will create a new future for pets.

Leveraging the latest breakthroughs in robotics, we are creating a consumer-grade AI Robot Pet. With a target price point of $200–$400 (approx. ¥30,000–¥60,000), we aim to fill a long-standing gap in the market: achieving lifelike emotional expression at an affordable price. Our product targets urban youth who “want a pet but cannot have one,” starting in the Japanese market and expanding globally.
