Proception
Proception is a Palo Alto and Mountain View robotics company building the dexterous robotic hand that humanoids are missing. Its flagship ProHand 1.0 packs 22 degrees of freedom, tendon-driven fingers and skin-like tactile sensors into a hand designed with input from surgeons - close enough to a human hand that robots can learn directly from human demonstration. A companion sensor glove, ProGlove, captures real human manipulation data at scale to train those movements. Founded in 2024 by former Tesla Optimus engineers Jay Li and Jack Xu, the company raised an $11M seed led by First Round Capital and is shipping its first hands to research labs and robotics companies.
Jay Li
Jay Li is the founder and CEO of Proception, a Palo Alto robotics startup building high-dexterity robotic hands for humanoid robots. A former electronics lead on Tesla's Optimus program, he left to bet that the fastest path to capable robots runs through hardware close enough to the human hand that machines can learn directly from people. His ProHand packs 22 degrees of freedom and skin-like tactile sensors; its companion ProGlove captures human manipulation data with no robot in the loop. In June 2026 Proception shipped its first hands, settled a Tesla trade-secret lawsuit, and closed an $11M seed round led by First Round Capital on the same day.
