Robotics startup Sunday has raised $165 million in a Series B funding round, pushing the company’s valuation to $1.15 billion as it works to bring autonomous household robots into real homes. The round was led by Coatue, with participation from Bain Capital Ventures, Fidelity Management & Research Company, Tiger Global, Benchmark, Conviction, and Xtal Ventures. Founded by Tony Zhao and Cheng Chi, Sunday is building AI-powered domestic robots designed to perform everyday household chores such as clearing tables, doing laundry, and loading dishwashers. Its flagship robot, Memo, is being developed as a fully autonomous assistant capable of operating in complex home environments. Unlike many robotics companies that focus on demonstrations in controlled environments, Sunday aims to deploy robots directly in households. The company plans to launch a beta program later this year, allowing early users to test the technology in real homes and provide feedback to improve the system. A major challenge in robotics is collecting real-world data that enables machines to understand unpredictable environments. Sunday has built a proprietary system called the Skill Capture Glove, which records human hand movements to generate large datasets that train its robotic models more efficiently. By combining proprietary data collection with AI models and vertically integrated hardware and software, the startup hopes to accelerate the development of robots capable of performing daily household tasks reliably. Investors believe this data-driven approach could help Sunday move beyond robotics demonstrations and into practical consumer products. With the new capital, the company plans to expand engineering teams, improve its AI robotics platform, and scale the deployment of its home robots through its upcoming beta program.
