About
Filip Aronshtein co-founded Dirac to automate the creation of mechanical assembly work instructions, the bottleneck that quietly delays hardware production lines across aerospace and defense. The company's flagship product, BuildOS, ingests CAD files and generates the step-by-step assembly drafts that previously took weeks of manual engineering. Under Aronshtein's leadership Dirac has raised $10.7 million from Founders Fund and Coatue, signed a strategic partnership with Siemens, and won early aerospace customers. He argues that the speed of American reindustrialization is gated by manufacturing engineering throughput, not CAD or CAM, and Dirac is built to attack that bottleneck directly.
