Sunday

Sunday Robotics is building personal home robots to reclaim the hours lost to repetitive household tasks. Founded in 2024, the company is focused on making generalized robots broadly accessible, enabling families to take back quality time.

Sunday came out of stealth in November 2024 and announced a $165M oversubscribed Series B in February 2025. The company's founders, Tony and Chung, are the research authors behind foundational papers in physical AI — including UMI, Diffusion Policy, and Aloha — work that became the basis for how the entire industry trains robots on human data. Tony dropped out of his PhD at Stanford to start Sunday when he realized the technology was no longer theoretical.

Despite being a ~100-person team with a fraction of the funding of competitors like Figure or Tesla, Sunday has attracted top engineers from both companies and is very much in the race to bring personal robots into the home. The company is preparing to launch its beta program, deploying robots into real households.

Sunday's culture is defined by low ego, high urgency, and genuine camaraderie. There are no office politics — team members across ML engineering, mechanical engineering, data collection, and operations regularly eat lunch together and connect over everything from work to the World Cup. It's a place where speed matters, resources are lean, and every person's contribution is visible and impactful.
