Building the AI substrate for the physical world.

Language models got abundant data, cheap rollouts, and automatic grading. The physical world has none of these yet. Artha Labs builds the missing layer: simulation-ready scenes, graders, and training-ready data.

Thesis
Physical-world deeptech AI as the unlock

AI for the systems where deployment is the moat.

We focus on physical-world systems — robotics, embedded & edge intelligence, and autonomy — where the hard problems are data, evaluation, and the gap between simulation and reality. These are exactly the places where AI is the unlock, not the product.

We seed a handful of deep hypotheses each year, kill the ones that don't work fast, and give real time and capital to the ones that do.

physics-accurate scenes are scarce

Pre-training gives the base model; SFT and RL make it task-specific. RL from experience is where recent gains come from: π*0.6 (RECAP) more than doubles throughput on its hardest tasks. That loop needs simulators and reward functions robots don't have yet.

What we do
80% · Artha Labs

Physical AI

A platform (scenes, robots, datasets, rollouts, evaluation, training), a robotics lab for sim-to-real validation and dynamics calibration, physical data infrastructure, and human judges in the loop.

The platform
Physical AI · Data, simulation, evaluation

The data & eval layer every robot brain needs.

Task requirements + scene description + eval criteria go in. An agentic loop builds simulation-ready scenes and graders, and turns existing video into training-ready data, sim-to-real validated. Neutral to whose model you're training.

An interactive product prototype is live — explore Scenes, Robots, Datasets, Rollouts, Evaluation and Training.
