Sunday Emerges from Stealth with $35 Million for Household Robot Memo

California-based robotics startup Sunday has emerged from stealth with $35 million in funding from Benchmark and Conviction to develop Memo, a household robot built to perform everyday chores such as dishes, laundry, and general tidying.

Memo is trained on a dataset of approximately 10 million real-world household activities collected from more than 500 homes using Sunday’s proprietary Skill Capture Glove. The glove records human movements and routines, enabling the robot to learn complex, multi-step tasks in dynamic residential environments.

Unlike humanoid robots, Memo features a stable rolling base and a silicone-clad exterior designed for safety and compatibility with home settings. The robot’s hardware and software were developed specifically for domestic use, allowing it to navigate kitchens, living rooms, and laundry areas while completing tasks such as loading dishwashers, folding clothes, and preparing simple drinks.

Sunday will begin its Founding Family Beta program in late 2026, selecting 50 households to test early versions of Memo and provide feedback. The company was founded by Stanford-trained roboticists Tony Zhao and Cheng Chi and employs a team of engineers and researchers with experience at organizations including Tesla, DeepMind, Waymo, Meta, and Neuralink.
