OS3
OS3 is a YC Summer 2026 (S26) company. Based in San Francisco, CA, USA. Team of 2.
About OS3
Summary
OS3 builds US-manufactured bimanual mobile semi-humanoid robots, training them on 150,000 hours of video data to handle physical labor tasks. The first target is hospitality, where OS3 operates deployments directly, with biotech as a second vertical. The robot replaces human labor on repetitive physical tasks such as towel folding, learning new tasks from as few as two to four hours of demonstrations.
Business model
Hospitality deployments priced from $2.50 per hour; developer units sold at $14,995 or leased at $1,800 per month, with a $99 refundable preorder deposit.
Go-to-market
Hospitality customers deploy through OS3 directly; developers and startups building in other verticals purchase or lease developer units to bring the same platform to their own applications.

Full Stack Robotics: Deploying US-Built Robots & Video Action Models
We are building robots, including custom actuators. Our first model is trained for the robot with 150k hours of video data. The robot, a mobile semi-humanoid priced, is already signed for deployments in hospitality and biotech. Our developer version lets anyone deploy robots in their own verticals, and we already have preorders. We are scaling American robotics while making it accessible to more businesses.
