The human layer of Embodied AI
Scale AI for humanoids
Human-robot interaction data for humanoid robots, generated in simulation.
Users play. Robots learn. We sell the data. Players do it for free, and every session becomes training data for the teams building humanoids.

The problem
Humanoid progress is gated by interactive human-robot data, not model size or compute.
There aren't enough physical humanoids in the world to collect the data needed to train them. So Vision-Language-Action (VLA) models starve for the diverse, interactive, multimodal data they depend on, because it barely exists yet.
How it works
We generate the decision-rich data teleop and video can't.
1.Play
People play and interact with robots in simple simulations.
2.Capture
We record it all: motion, voice, language, decisions.
3.Structure
Each session becomes clean, labeled training data.
4.Train
Robot models learn from it, and we measure the gains.
5.Deploy
The skills transfer to real and simulated humanoids.
The moat
15× cheaper data that compounds while hardware burns cash.
Cost per usable data-hour
$135
Teleoperation
$9
Synthium
≈ 15× lower
Players generate the data for free because it's genuinely fun, like a Roblox for robotics.
No teleop wages, near-zero marginal cost, and every new player makes the dataset stronger. The gap compounds into a data moat.

Our edge
We capture the signal everyone else skips.
Active, not passive
The field scrapes video and teleop snapshots. We run a live loop of humans and robots interacting in real time.
Human + synthetic
Pure synthetic data is hollow. We're native to simulation and add what it can't fabricate: real human behavior and decisions.
Interaction, not dexterity
Billions chase robot hands. We own how humanoids behave safely around people, where they actually have to work.
The human know-how inside every robot.
We start as the dataset others can't make.
