Dirac

Dirac, Inc. is a software company founded in New York in 2022 by CEO Fil Aronshtein and CTO Peter Weiss. The company's mission is to bridge the gap between mechanical design and manufacturing that widened when CAD software moved engineers away from the production floor.

The founders, who met as electrical engineering students at Johns Hopkins University, share a background in hardware engineering and robotics. Aronshtein's experience on the shop floor at Northrop Grumman, where he witnessed the use of archaic infrastructure like PowerPoints for complex assembly instructions, inspired the creation of Dirac. The team intentionally hires individuals with hardware and manufacturing backgrounds who have transitioned into software to ensure a deep understanding of the problem they are solving.

The company's flagship product is BuildOS, a software-as-a-service (SaaS) platform that automates the creation of high-quality work instructions for mechanical assemblies. By uploading a CAD file, users can generate assembly instructions in minutes or hours, a process that traditionally takes weeks. The platform automatically determines the optimal assembly order, produces 3D renderings and animations, and generates text for each step. BuildOS is designed to automate about 80% of the work, allowing engineers to manage the remaining 20% by annotating, reordering, and manipulating the content. Recent additions to the platform include Operator+ and the Runs Dashboard. Operator+ enables shop floor operators to follow digital instructions while capturing real-time performance data and providing feedback. The Runs Dashboard provides a centralized location for engineers and supervisors to review these metrics and suggestions.

Dirac operates in the advanced manufacturing, aerospace, defense, automotive, and mobility sectors, serving clients that range from tier I-III suppliers to global OEMs. Notable customers include Ancra Aircraft, a major supplier for Airbus and Boeing. The company generates revenue through its venture capital-backed SaaS platform. Dirac has secured $3M in seed funding and recently raised $10.7M in a round backed by Founders Fund and Coatue. It has also established a strategic partnership with Siemens to better connect product design with manufacturing execution.
