Memo: The Future of Home Chores

Sunday's innovative Memo robot tackles tedious tasks such as loading dishwashers, folding laundry, clearing tables, and even brewing coffee.

Featuring a stable wheeled design with extendable arms, Memo prioritizes safety and precision in real-world homes over humanoid forms.

Founded by Stanford robotics expert Tony Zhao, Sunday emerged from stealth in late 2025 with $35 million in seed funding.

The company's proprietary Skill Capture Glove enables affordable data collection from human demonstrators, fueling a massive data flywheel.

This full-stack approach allows unmatched iteration speed, delivering demos with industry-leading manipulation skills in just three months.

With the new capital, Sunday plans beta deployments of Memo in late 2026, targeting full-scale production thereafter.

The investment underscores the transformative potential of AI robotics to alleviate household labor shortages and reshape daily life.

Positioned for affordability akin to high-end laptops, Memo could democratize home automation for millions worldwide.
