The robotics firm Sunday has secured a new funding round, reaching a valuation that qualifies it as a unicorn, which implies it is valued at over $1 billion, as announced on Thursday.

Sunday has reported that it has successfully raised $165 million with a valuation of $1.15 billion in a Series B funding round spearheaded by Coatue Management. Other backers participating in this round include Tiger Global, Benchmark, and Bain Capital Ventures.

The company emerged from stealth mode late the previous year and has already accumulated a waitlist of 1,000 individuals, according to Bloomberg.

Founded by Tony Zhao and Cheng Chi, Sunday aims to develop a household humanoid robot named Memo that can assist with chores such as laundry and clearing tables.

For decades, experts have attempted to create a robot of this kind — reminiscent of Rosie from “The Jetsons” — but have faced challenges repeatedly, primarily due to insufficient training data for teaching robots to consistently handle objects of varying weights, textures, and fragility (such as towels compared to wineglasses). As advancements in AI technology continue, a fresh wave of robotic innovations is entering the market, aiming to resurrect the humanoid assistant.
