About Us

Manukai stands for Manu_facturing and Kai_zen, a Japanese methodology of continuous improvement that translates to “change for better.” In ancient Greek, Kai_ros means “the opportune moment.”

We are a spin-off from ETH Zürich, aiming to bridge the gap between metal part design and machining. Our AI-powered technology empowers manufacturers to prioritize their clients’ needs and deliver high-quality products to the market. Our primary focus is making an immediate impact, with client satisfaction as our utmost priority.
