Companion robot startup RBY tech raised over $1.37M in angel funding after its RBY mini robot sold out in preorders, generating over $137K in sales on day one.
Hangzhou-based RBY tech has completed an angel funding round of over RMB 10 million (approx. 1.37 million USD), led exclusively by Junchen Capital. The funds will be used to scale production and optimize user experience for its flagship product, the RBY mini companion robot, as well as to develop long-term companionship models and expand into multi-form robot products.
Founded in 2019, RBY tech focuses on emotional companionship robotics. Its RBY mini robot emphasizes a deep interaction loop—“adoption, training, and bonding”—allowing the robot to evolve alongside users and develop a unique personality. The company has built proprietary technologies including personality generation algorithms and emotional engines.
Prior to hardware commercialization, RBY tech’s content accounts under the “Wo Xi Erbai” brand amassed over 7 million followers, establishing strong emotional brand recognition. In June 2025, RBY mini opened for full-price preorders, generating over RMB 1 million (approx. 137,000 USD) in sales on day one and selling out entirely within five days.
According to Grand View Research, the global smart companion market reached USD 28.19 billion in 2024, with a projected CAGR of 30.8%, supporting RBY tech’s shift from content monetization to robot-centric hardware sales.
