DE Design Works vs Sigma Design: overview

DE Design Works

DE Design Works was founded in 2002 and operates from Chesterfield, Missouri with a team in the 11 to 50 employee range. Its scope centers on PCB and hardware design for rugged industrial, medical, and military applications alongside embedded software and firmware, including secure OTA update signing, staging, and rollback, and embedded Linux board support package bring-up. For an RFP built around a ruggedized or regulated product, having electronics and firmware design under one small, senior vendor reduces the integration risk of coordinating separate hardware and software contractors.

Sigma Design

Sigma Design (operating as SIGMADESIGN) was established in 1994 in Portland, Oregon and is now headquartered in Camas, Washington with approximately 283 employees across five continents. Its stated scope covers mechanical design and engineering, industrial design, testing, onsite contracting, and software and firmware engineering, positioning itself as a full product design and engineering partner rather than a firmware-only vendor. For an RFP that groups industrial design, mechanical engineering, and firmware into one deliverable, Sigma Design's breadth and headcount give it more parallel-program capacity than most boutique bidders on this list.

DE Design Works vs Sigma Design: pros and cons

DE Design Works
+ PCB and hardware design for rugged, regulated applications sits alongside firmware in the same firm, not a separate contractor
+ Secure OTA update work covering signing, staging, and rollback is a specific, verifiable technical capability for a security-conscious RFP
+ 23 years of operating history gives a track record to reference-check against
+ Rugged industrial, medical, and military application experience matches vendor-qualification requirements common in those RFPs
- 11 to 50 employees limits concurrent capacity compared to larger competing bidders
- Public case studies naming specific past programs are limited, so verifying track record needs direct reference requests
- No published pricing or minimum engagement threshold
Sigma Design
+ 283 employees across five continents give substantially more parallel-program capacity than most boutique firms on this list
+ 31 years of operating history under continuous product-design focus
+ Industrial design and mechanical engineering sit alongside firmware, matching how a full product RFP is often scoped
+ Onsite contracting option can place engineers directly with a client team for close-coordination programs
- Firmware is one discipline inside a much broader product-design practice, not the firm's primary specialty
- No published pricing or minimum engagement figure
- Public case studies specific to firmware-only engagements, versus its broader product design portfolio, are limited
