Physical Intelligence (π)

Physical Intelligence (π) is not a robot hardware company but the leading foundation model lab for physical AI, developing general-purpose robot learning systems that can be deployed across diverse hardware platforms. Co-founded by Sergey Levine, Chelsea Finn, and Karol Hausman — three of the world's most cited robotics researchers — π's π0 and π0.2 vision-language-action models have achieved unprecedented zero-shot generalization across robot morphologies. Its approach of treating robot learning as a foundation model problem, rather than a per-robot-per-task engineering challenge, has drawn $470M+ and a $2.4B valuation despite selling no hardware.
