New Jersey-based, owned and operated, Sigma Design Company continues to be a dynamic and trusted manufacturing partner for businesses in the state and beyond. Not only are we focused on executing every client engagement seamlessly, on time, and budget; we are also intent on helping to expand manufacturing in New Jersey by leveraging our experience, knowledge, and customer-centric approach.

For 25 years, we have helped transform our clients’ ideas into highly effective product solutions. To date, we have delivered more than 1,000 successful design and design/build projects while saving our clients hundreds of thousands of dollars in manufacturing costs.

When President and CEO Gerard (Jerry) Lynch purchased the original Sigma Design Company in 1999, it was a small four-person machine design company. Within three years, the firm had evolved into a design-build shop, and just a year later, we were managing a number of projects for leading global companies as well as the US Navy.
