Simulating Agents Running Industrial Companies

What is your company going to make? Please describe your product and what it does or will do.

We build high-fidelity simulations of industrial operations that let labs train AI agents to actually run power plants, factories, and datacenters. Our core product is a simulation environment that captures the complexity of real-world energy and industrial systems. We aim to be the foundation for training models that control mission-critical infrastructure in the $5T US industrial sector.

Where do you live now, and where would the company be based after YC?

We live in San Francisco, CA, and the company will stay based here after YC.

Explain your decision regarding location.

San Francisco has the best access to AI talent and early customers in energy and industrials. We're already here and plan to stay.
