Sigma Design vs Integra Sources: overview

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.

Integra Sources

Integra Sources was founded in 2014 and is headquartered in Astana, Kazakhstan, with a team reported between roughly 24 and 51 employees across Asia, North America, and Europe. The company's scope covers electronic device design, firmware and software development, and full-cycle engineering from PCB and FPGA design through robotics and connected-product monitoring systems, with more than 250 completed projects for over 100 clients across Europe, the USA, Australia, and Asia cited as its delivery track record. For an RFP evaluating project-volume evidence, that 250-project figure is a specific, referenceable claim.

Sigma Design vs Integra Sources: pros and cons

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
Integra Sources
+ More than 250 completed projects across four continents is a specific, checkable delivery-volume claim
+ Full-cycle scope from PCB and FPGA design through firmware and connected-product monitoring reduces vendor coordination
+ 11 years of operating history with a client base spanning Europe, the USA, Australia, and Asia
+ Robotics engineering experience is a specific capability not every embedded firmware vendor lists
- Reported team size varies between roughly 24 and 51 across sources, worth confirming for large concurrent RFP capacity needs
- No published pricing or minimum engagement figure
- Its Kazakhstan headquarters may raise timezone or in-person coordination questions for some North American or European RFPs
