Adaptive robots that combine force control and AI for contact-rich work

An adaptive robotics company founded in 2016, headquartered in Shanghai with operations in the US and Singapore, led by founder and CEO Shiquan Wang. Its 7-axis force-controlled Rizon arms (2019) and force-controlled Moonlight parallel robot (2023) automate contact-rich work such as polishing, precision insertion and cable assembly. Flexiv became a unicorn in 2022 and in March 2026 took a strategic investment led by Invus to scale globally. In Japan, Kurabo has sold Rizon since January 2025. Its founder also co-founded Noematrix.

On January 9, 2025, Kurabo began selling Rizon (4 kg, 4 kg high-precision and 10 kg) in Japan through a partnership with Flexiv. KURAVIZON pairs it with KURASENSE 3D vision for tasks like gripping cables and other flexible parts and connector insertion. Named customer production deployments are not yet confirmed.
Flexiv made its first appearance at the International Robot Exhibition at Tokyo Big Sight on December 3–6, 2025, demonstrating Rizon and other adaptive robots, including a massage demo station.
Flexiv reportedly collaborated with Siemens in May 2024. That September it also developed an automated fish-fillet shaping solution.
