About
Dirac is an assembly automation software company that bridges the gap between CAD design and manufacturing by automatically generating precise work instructions from CAD files. Its flagship product, BuildOS, uses physics and geometry simulations to unify ERP, PLM, and MES systems — automating ECOs, assembly sequencing, and work instructions that traditionally take weeks or months to draft manually. Dirac enables manufacturers to create work instructions for complex mechanical assemblies in minutes, with use cases spanning aerospace, defense, and precision manufacturing. In August 2025, Dirac announced a $10.7M funding round and a strategic partnership with Siemens to accelerate the integration of BuildOS with Siemens' manufacturing software ecosystem.
