Sunday Robotics

About Sunday Robotics

Sunday (Sunday Inc.) was founded in 2023 by Tony Zhao and Cheng Chi — Stanford roboticists and authors of ALOHA, ACT, Diffusion Policy and UMI. The company came out of stealth on 19 November 2025 and in March 2026 raised USD 165M (Coatue, Bain Capital Ventures, Fidelity, Tiger Global) at a USD 1.15B valuation.

Memo is not a bipedal humanoid: a torso with arms stands on a wheeled column and pincer grippers replace fingers. It still folds laundry, clears the table into the dishwasher and pulls an espresso. The ACT-1 model learned from about 10 million demonstrations recorded by people with the Skill Capture Glove in more than 500 homes.

The robot is not on sale yet: a free "Founding Family" beta for about 50 US households starts at the end of 2026, and no price has been announced (a hand-built unit costs about USD 20,000 today).

For ROBOTio, Sunday signals where home robotics is heading; it is no competitor for the event market. We watch it for hospitality and care clients.

Who Sunday Robotics makes sense for

Households

Laundry, tidying, kitchen — the maker's only target scenario.

Hotels and care (outlook)

Once the robot is available, we advise on a housekeeping choice.
