Praxis Robotics

Praxis Robotics (YC S26; launched on YC as Praxis AI) supplies training data for physical AI. Robots learn to act by watching humans work, so Praxis partners with businesses to record egocentric human demonstrations — first-person video of how tasks are actually done in factories, warehouses, homes, refineries, assembly lines and pharmaceutical and lab settings — and licenses the processed data to frontier labs and humanoid-robot teams. Partner businesses are paid for every usable hour, pitched as a second revenue line from operations they already run. Depending on the task it captures egocentric video, stereo RGB, IMU, wrist-camera views, glove kinematics, haptics, 3D scans and dense annotations, delivered calibrated, synced, pose-tracked, QA'd and PII-scrubbed, and it builds custom capture hardware through a team in Shenzhen. The company says it runs collections across 150+ environment types on five continents and can reach 60,000 workers through partners ranging from small shops to conglomerates it describes as publicly listed or unicorn-scale — company claims, not independently verified. Founded in 2026 in San Francisco by CEO Rohan Seelamsetty (Computation and Cognition at Penn, Apollo Fellow at Oxford), COO Dev Karpe (Wharton Huntsman Program; investment banking and Fortune 500 supply-chain operations) and CTO Tommy Li (UPenn CS and finance; tech private equity at Morgan Stanley, industrial-tech venture capital at Andreessen Horowitz, IEEE-published research at NASA JPL and PerceptIn Robotics). Team size 3 per the YC directory. No funding amount or valuation has been disclosed beyond YC backing.
