Nov 2025Undisclosed stageConviction; Benchmark$35M-Sunday is a California-based robotics startup founded in 2023 by Stanford-trained roboticists Tony Zhao and Cheng Chi, developing Memo, an autonomous household robot designed for chores like dish handling, laundry, food preparation cleanup, and general home organization. The robot features a stable rolling base, soft silicone-clad design, and residential hardware, trained on 10 million real-world household episodes from over 500 homes using a patented Skill Capture Glove. Emerging from stealth, Sunday raised $35 million from Benchmark and Conviction around November 19, 2025, to advance Memo toward a Founding Family Beta with 50 selected households in late 2026. The team includes 25 engineers from Tesla, DeepMind, Waymo, Meta, and Neuralink. This funding supported initial development and beta applications, which opened November 19, 2025, amid strong demand. Sunday focused on data collection from real homes to enable multi-step tasks in unstructured environments, differentiating from industrial robotics. In a subsequent oversubscribed Series B round announced March 12, 2026, Sunday raised $165M at a $1.15B valuation, led by Coatue with participation from Bain Capital Ventures, Fidelity, Tiger Global, Benchmark, Conviction, and Xtal Ventures, bringing total funding to $200M. Funds enable beta deliveries starting months later, scaling engineering 3x, research 4x, and data collection 5x by year-end, with thousands of beta applications received. Sunday competes in consumer robotics against Tesla Optimus, Figure AI, and 1X, emphasizing full-stack AI-physical systems for reliable daily home use over teleoperated demos. Investors like Benchmark highlight potential in residential deployment, with pilots collecting operational data for model training.
