Sunday Robotics
Sunday is a household robotics company founded by Stanford PhD roboticists Tony Zhao, its chief executive, and Cheng Chi, its chief technology officer. It emerged from stealth on 19 November 2025 with Memo, a personal robot for chores such as dishes, laundry and tidying. Memo has no legs: a torso extends from a thick rolling platform, which avoids the balance problems of walking humanoids. It is trained from about 10 million episodes of real household routines collected in more than 500 homes with Sunday's patented Skill Capture Glove, a wearable that records how people move, clean and organise. Sunday launched with US$35 million from Benchmark and Conviction and opened applications for a Founding Family Beta with fifty households, starting in late 2026. In March 2026 it raised a US$165 million Series B at a US$1.15 billion valuation, led by Coatue Management, with Tiger Global and Bain Capital Ventures, and reportedly had about 1,000 people on its waitlist.
π‘Notable Achievement: Sunday raised a US$165 million Series B at a US$1.15 billion valuation in March 2026, four months after emerging from stealth with Memo.

Memo
Manufactured by Sunday Robotics
Memo is a home-focused humanoid-style robot developed by Sunday Robotics to autonomously perform domestic chores such as dishwashing, laundry folding, tidying, and espresso preparation. Standing 1.7 meters tall on a wheeled base, it features a torso with two multi-DoF arms and dual grippers, capable of reaching from floor level up to around 2.1 meters (7 feet). Designed for family environments, Memo emphasizes safety and stability through a low center of gravity, compliant control, and a soft silicone exterior. It learns from real household data via Sundayβs Skill Capture Glove, mastering long-horizon tasks in unstructured homes.
