Leo AI

Leo AI is a Cambridge, Massachusetts company building what it calls the world's first AI purpose-built for mechanical engineering. Its engineering design co-pilot, powered by a proprietary Large Mechanical Model (LMM) trained on millions of real-world products and engineering standards, turns text, sketches and specifications into production-ready 3D CAD models. Leo integrates with CAD and PDM systems to answer technical questions, source parts, run mechanical calculations and generate design concepts, and says it helps teams cut engineering time by up to 70%.
