We raised $165M at a $1.15B valuation to stop doing demos.
2026 is about 1) deployment and 2) research. We will start shipping Memo with our new frontier models in a few months.
Our series-B is led by Coatue, with Thomas Laffont joining the board. ->🧵
If you took apart your appliances when you were a kid, @SundayRobotics will feel like home.
We are hiring Mechanical Engineers to help us bring Memo to the world. You will own critical hardware from concept to production, working closely with our AI team to deliver a category defining product. Careers page below!
We found that Memo understands object affordances: depending on whether an object is larger or smaller than its hand, it selects a one-handed or two-handed grasp.
1. When I first visited the house in February, I was expecting a polished demo. There was an impressively generalizable shoe organizing policy, but struggled a bit and the robot itself was hacked and held together with clamps. But I walked away incredibly blown away...
It started with @tonyzzhao and @chichengcc in their apartment in April 2024. We moved out of our hacker house in Mountain View in February of 2025 with 10 people. Today, we have over 30 team members. Velocity of progress to a real, useful robot is everything to us. The progress we've shared so far with Memo and ACT-1 was only possible through building an incredible team focused on the same goal.
If you share the same goal, come build: https://t.co/vO8MDUWYd7
5. From that visit it was obvious that the groundwork would lead to these exciting breakthroughs. I feel incredibly lucky to be a part of @sundayrobotics and help make Memo clamp free! Thanks @tonyzzhao@chichengcc@clayhaight !
When training ACT-1, we treated data from diverse, long-horizon tasks in the wild as a first-class citizen. This makes generalization the default, not an exception.
The capability envelope expands. More to come.
