Luminal builds an ML framework and compiler that generates optimized GPU code, accelerating model speed while simplifying deployment and reducing idle GPU costs. The platform treats optimization as a search problem to automatically discover complex optimizations that would typically require weeks of manual GPU engineering. The company also sells compute, focusing on optimization techniques that squeeze more performance out of its infrastructure. Founded in 2025 by a former Intel chip designer alongside ex-Amazon and ex-Apple engineers, Luminal was part of YC's Summer 2025 batch.
