A mechanical engineer crossed medical devices, building systems and energy technology before taking charge of a family-owned wire maker. His first move was not a grand manifesto. It was to walk the plants and listen.

Maingen is a Y Combinator (S26) startup building reinforcement learning environments for industrial operations - the roughly $5 trillion slice of the US economy that runs factories, power plants, and solar farms.

The company sells the environments and datasets that let AI labs train and evaluate models on messy, long-horizon physical-world work.
