What Sigma Design does

Sigma Design Company, LLC is a privately held U.S. engineering and manufacturing services firm founded in 1999 by Gerard J. (Jerry) Lynch, who acquired a four-person machine design predecessor in Union, New Jersey. The company operates from a 20,000-square-foot Technology Commercialization and New Product Manufacturing Center at 200 Pond Ave in Middlesex, New Jersey, and has grown to nearly two dozen employees with annual revenues exceeding $4 million. Its core offering is a turnkey electromechanical product development cycle - design, engineering, manufacturing, testing, and validation - executed in-house at a single facility that combines CAD, finite element analysis (FEA), computational fluid dynamics (CFD), CNC machining, ASME/AWS-certified welding, UL 508A-certified panel building, PLC and HMI programming, and rapid prototyping. The firm is NVBDC-certified veteran-owned and holds licensed Professional Engineers in New York and New Jersey.

The company serves a broad vertical mix - including medical devices and life sciences, industrial water and filtration, clean energy, ag-tech and food processing, defense and government, and consumer appliances - and has completed more than 1,000 design and design/build projects since inception. Engagements span program-level work for the U.S. Navy, U.S. Army, U.S. Bureau of Reclamation, U.S. Maritime Administration, Pratt & Whitney, General Dynamics, Electric Boat, Pfizer, Voith Hydro, Welch's Foods, Glen Mills/Zellwerk, Crop One, and 3M/CUNO, among others. Its Sigma Industrial Water Group sub-brand packages proprietary, patent-pending filtration technology into a product line (Models 4613, 4614, 4615, 4577, 4583, 4570, 4588), with the Model 4614 jointly incorporating Spiral Water Technologies' patented pre-filtration and co-marketed at the April 2026 Design2Part trade show.

Commercially, Sigma Design sells three integrated revenue streams - project-based engineering and design services, build-to-print and custom industrial manufacturing, and hardware sales of branded water filtration products - priced on a custom quote basis per engagement, with distribution exclusively direct through consultative sales, case studies, content marketing, and trade show presence. The company carries certifications across ISO 13485, FDA 21 CFR Part 820, CE Mark, multiple NSF standards, IEC/UL 60601, and others, which qualify it for regulated work in medical, food, defense, and water-treatment end markets. No institutional investors, funding rounds, M&A, or parent-company ownership are disclosed; ownership rests with the Lynch family and operating management.
