About Cortex AI
Summary
Cortex AI collects and supplies large-scale, real-world robotics training data to frontier AI labs building foundation models and general-purpose robots. Its datasets cover egocentric human video annotated with hand and body pose, depth, and subtask labels, plus robot trajectories gathered from manipulators and humanoids in live industrial settings. The work it replaces is the slow, expensive, and narrow data collection labs would otherwise run themselves.
Business model
Data sold to frontier labs, with workplaces paid to host collection and evaluation sessions through the Cortex Marketplace.
Go-to-market
Frontier AI and robotics labs are the buyers, reached through direct engagement; workplaces join as data-collection hosts via the Cortex Marketplace, expanding supply and reach simultaneously.
From the Y Combinator listing
Large-scale real-world robot & human data for embodied AI
Cortex AI builds the world’s most diverse and large-scale real-world workplace robot & egocentric dataset — where the physical world becomes the next training and evaluation set for embodied AI. We power frontier labs developing robotics foundation models and general-purpose robots by providing the data they need: 1️⃣ Egocentric Data — real-workplace human video with hand/body pose, depth, and subtask labels. 2️⃣ Robot Data — trajectories collected from manipulators and humanoids in real industry settings. 3️⃣ Human-in-the-Loop Rollouts & Evals — real-world deployments with remote operators who recover robots when they fail, capturing data that feeds back into training and continuously improves models. Additionally, through the Cortex Marketplace, workplaces get paid to host data-collection and evaluation sessions, while labs access the in-the-wild data that truly matters. This draws on Lucas’s previous experience as co-founder of Carousell, a C2C marketplace that scaled to a $1B+ valuation.
