Sunday, a robotics startup founded by Tony Zhao and Cheng Chi, raised $165 million in Series B funding at a $1.15 billion valuation led by Coatue Management. The company is developing a humanoid household robot called Memo designed to help with domestic tasks like laundry and clearing tables, with 1,000 people already on the waitlist since emerging from stealth late last year. This represents another major attempt to solve the decades-old challenge of building reliable household robots that can handle objects of varying weights, textures, and fragility.
