Dirac Secures $10.7M and Siemens Partnership to Digitize Manufacturing Memory, Aerospace Sector Stands to Gain

Dirac, Inc., a rising force in assembly automation software, has announced $10.7 million in funding from Founders Fund and Coatue, alongside a strategic partnership with Siemens aimed at transforming how manufacturers bridge engineering intent with production execution. At the heart of this push is BuildOS, Dirac’s newly launched platform that automates the creation of model-based work instructions, an innovation poised to reshape aerospace manufacturing where precision, repeatability, and tribal knowledge are mission-critical.

BuildOS: Turning CAD into Context

Dirac’s BuildOS platform translates CAD files and bills of materials into animated, physics-aware, step-by-step work instructions. These instructions are dynamically updated and enriched with embedded tribal knowledge, enabling technicians to execute complex tasks with minimal onboarding. For aerospace firms, where production often involves low-volume, high-mix builds and legacy documentation, this leap in contextual clarity could dramatically reduce errors and accelerate throughput.

Early adopters like Ancra Aircraft, which supplies cargo loading systems to over 60% of the global freighter fleet, have already reported a 95% reduction in instruction creation time and significant gains in quality assurance.

Siemens Partnership: Closing the Loop from Design to Execution

Siemens, a global leader in PLM and digital manufacturing solutions, has partnered with Dirac to integrate BuildOS into its ecosystem. The collaboration aims to connect design tools like CAD and PLM with downstream ERP and MES systems, creating a seamless pipeline from engineering to shop floor execution. Initial implementations have already shown improvements in manufacturability and agility, and Siemens plans to deepen integration across its digital manufacturing portfolio.

For aerospace contractors managing complex build sequences and compliance-heavy workflows, this partnership offers a pathway to smarter, more adaptive production planning.

Why Aerospace Executives Should Pay Attention

Dirac’s founders, with backgrounds in aerospace, automotive, and defense manufacturing, built the platform not for Silicon Valley’s idea of production, but for the realities of American shop floors. Their approach reflects a growing recognition that the future of aerospace manufacturing depends not just on machines, but on memory, codified, scalable, and ready for the next generation of builders.

• Preserving Tribal Knowledge: As senior technicians retire, BuildOS captures and distributes their expertise, mitigating the risk of knowledge loss in critical aerospace programs.
• Accelerating Onboarding: Interactive instructions reduce ramp-up time for new hires, a key advantage in a sector facing skilled labor shortages.
• Reshoring with Intelligence: BuildOS supports the U.S. manufacturing resurgence by enabling repeatable, high-quality builds without relying on legacy documentation or manual walkthroughs.
