About
First Resonance is a Los Angeles-based manufacturing software company founded in 2019 that builds the ION Factory Operating System — a modern, cloud-native manufacturing execution system (MES) purpose-built for agile, high-mix, complex manufacturers in sectors such as aerospace, defense, robotics, space, and advanced hardware. Unlike legacy MES platforms designed for high-volume, low-variation production, ION is built for manufacturers that produce intricate, low-volume products with complex assembly processes, regulatory traceability requirements, and frequent engineering changes — a profile common in aerospace and defense new-space companies.
