Sunday

Sunday emerged from stealth in November 2025, announcing its personal robot, Memo, designed to assist families by taking over chores such as washing dishes, doing laundry, and tidying up. Instead of a bipedal humanoid design, Memo features a wheeled base for increased stability and safety, a lower weight, and is clad in a soft silicone shell. The robot stands 1.7 meters tall, weighs 77 kg, and has a telescoping column that allows its arms to reach from the floor to overhead shelves. A key differentiator for Sunday is its data collection method. The company developed the proprietary 'Skill Capture Glove,' a wearable device that records human movements as people perform chores in their own homes. This approach has allowed Sunday to build a dataset of approximately 10 million real-world household routines from over 500 homes, which trains its foundation model, ACT-1. This 'in-the-wild' data enables Memo to adapt to the unpredictable nature of home environments.

The company's business model aims to make home robots accessible, with a target price point similar to a high-end smartphone or laptop, rather than a car. Sunday initially raised $35 million in a funding round led by Benchmark and Conviction. In March 2026, the company secured an additional $165 million in a Series B round led by Coatue, with participation from Bain Capital Ventures, Fidelity Management & Research Company, Tiger Global, and existing investors. This round brought Sunday's valuation to $1.15 billion. The company plans to stop giving demos and focus on deployment, with a 'Founding Family Beta' program scheduled to launch in late 2026, delivering robots to 50 selected households.
