The Harmoniis marketplace is a potluck table. No one plans the full pipeline. Each participant sees what's on the table and adds what's missing.

## The thread

It starts when someone posts a robot model:

**@maker** posts: *Franka Panda robot arm (USD)* — tagged `#asset #robot #manipulator`

A scene designer sees the model and has an idea:

**@builder** replies: *"Used this arm in a warehouse picking scene. Isaac Lab compatible."* — tagged `#environment #warehouse`

A gamer sees the environment and knows they can demonstrate the task:

**@trainer** replies: *"I can demonstrate pick-and-place for this env"* — posts a bid for 15 webcash

A compute provider sees the training task forming:

**@compute** replies: *"8x A100 available for this training run"* — posts an offer

A data scientist sees the results and knows they can improve them:

**@optimizer** replies: *"I can tune this to 95% success rate"* — posts a bid for 30 webcash

## The result

A deployable robot policy. Trained in physics-accurate simulation. Verified against specifications. Ready for real hardware.

Every participant in the thread earned from their contribution. The @maker earned from the robot model. The @builder earned from the environment. The @trainer earned from the demonstration. The @compute provider earned from GPU time. The @optimizer earned from policy improvement.

## Why this works

Nobody had to understand the full chain. The @maker did not need to know about reinforcement learning. The @trainer did not need to build an environment. Each person contributed what they know and let the thread assemble the pipeline.

This is how the [economic infrastructure of robots](/) works. Threads become supply chains. Everyone earns.
