Sunday Robotics
Integrator / OEM · US
Mountain View maker of Memo, a two-arm wheeled home robot trained on real-household data captured with its Skill Capture Glove.
Sunday builds Memo, a two-armed wheeled home robot that handles household chores — clearing tables, loading dishwashers, laundry, tidying, making espresso — autonomously and out of the box in homes it has never seen. The differentiator is the data pipeline: instead of teleoperation or synthetic simulation, Sunday equips real families with a patented Skill Capture Glove, a wearable that records human motion, and has collected training data across hundreds of homes, producing millions of episodes of genuine household routines. Memo runs on learned policies plus an expanding Skill Library, adding new skills monthly. Sunday calls data — not models or compute — the binding constraint on home robotics, and treats real households as the training set.

Evidence boundary
Original analysis and independent corroboration remain under development. Commercial scale and durable technical advantage remain under review.
What makes it defensible
A real-home data pipeline (glove-based capture across 500+ households, 10M+ episodes) that buys manipulation generality no simulation farm can synthesise.
Position in the stack: Integrator-OEM for the consumer home: owns hardware, data collection and policy training end to end, selling directly to households rather than through industrial integrators.
