Sunday Raises $165M at $1.15B to Deploy Household Robot Memo by Thanksgiving
Household robotics startup Sunday announced a $165 million Series B at a $1.15 billion valuation this week, with plans to begin deploying its Memo home robot to real households by Thanksgiving 2026.
The round was led by Coatue Management, with participation from Benchmark, Tiger Global, Bain Capital Ventures, Fidelity, and others. Coatue co-founder Thomas Laffont joins the board.
What Memo Does
Memo is a wheeled humanoid designed for domestic environments. Its first target workflow is the kitchen: clearing plates and glassware from tables, disposing of food scraps, and loading dishwashers. Sunday has trained the robot on footage from hundreds of real homes, where objects, layouts, and clutter vary widely.
The core of Sunday's data strategy is the Skill Capture Glove โ a device worn by human demonstrators that records precise movements and converts them into training episodes. Sunday says it has captured tens of millions of movement episodes, creating a proprietary dataset it believes gives it a lead over competitors relying on synthetic or simulated data.
From ALOHA to Deployment
Sunday was founded by Tony Zhao and Cheng Chi. Zhao previously led the ALOHA imitation learning project at Stanford, which became a widely cited benchmark for dexterous robot manipulation. He left his PhD program in 2024 to build Sunday.
"We raised our Series B to stop giving demos," said Zhao. "Now, we're focusing entirely on deployment, with Beta deliveries starting in just months."
Beta deliveries are expected later this year, with 1,000 households already on the waitlist. The company says new skills are added to Memo's library monthly.
