DE Design Works vs Bresslergroup (Delve): overview

DE Design Works

DE Design Works was founded in 2002 and is based in Chesterfield, Missouri, with a team in the 11 to 50 employee range. The firm pairs custom PCB hardware design with embedded firmware development for industrial, medical, and military clients, which reduces handoff friction on projects where hardware and firmware need to be co-designed rather than contracted separately. Public case studies and named clients are limited, so most specific claims beyond the company's core services rely on its own materials.

Bresslergroup (Delve)

Bresslergroup was founded in 1970 in Philadelphia, Pennsylvania, and reports roughly 83 employees. In 2021 the firm merged with the Midwest design consultancy Delve under Trinity Hunt Partners' ownership, and by June 2022 the combined company adopted the single Delve brand name, so new engagements are contracted under that name even though the Bresslergroup engineering history and team carried over. Its practice covers new product definition and development, including industrial design, mechanical and electrical engineering, and embedded software, for categories spanning consumer IoT products to medical devices.
