Sunday Robotics has raised $165 million in its Series B funding round led by Coatue at a valuation of $1.15 billion.

The funding round saw participation from  Bain Capital Ventures, Fidelity Management & Research Company, Tiger Global, and existing investors Benchmark and Conviction.

The fresh capital will accelerate the development and launch of the company's domestic assistant robot, named Memo, designed to handle household chores like laundry and dishwashing.

“We raised our Series B to stop giving demos. Now, we're focusing entirely on deployment, with Beta deliveries starting in just months,” said Tony Zhao, CEO of Sunday. 

“Data has always been the biggest bottleneck in robotics. We built the only pipeline that turns the complexity of real-world homes into autonomous intelligence at scale," added Zhao.

Sunday Robotics, which was founded in April 2024 by Zhao and Cheng Chi,  emerged from stealth last year in November.

The robotics space have been attracted significant investor interest.

Earlier this month, Mind Robotics raised $500 million in a Series A funding co-led by Accel and Andreessen Horowitz.

Last year in September, Figure got over $1 billion in committed capital in its latest funding round that valued the firm at $39 billion.

US tech companies including Tesla, Nvidia and Meta are racing to develop humanoid robots while facing stiff competition from China.
