Voler Systems vs Sigma Design: overview
Voler Systems
Voler Systems has operated from Sunnyvale, California since 1979, a 46-year track record that few independent electronic design consultancies can match, with a current team of roughly 22 engineers. The firm's scope combines analog circuit design, FPGA programming, and embedded firmware, with a specific emphasis on ultra-low-power wearable and biomedical sensor products where power budget, sensor integration, and wireless transmission all have to be engineered together. For a procurement evaluation weighing longevity and financial stability as a vendor-risk factor, Voler's decades of continuous operation carry real weight.
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.

Voler Systems vs Sigma Design: pros and cons
| Voler Systems | |
|---|---|
| + | 46 years of continuous operation is an unusually strong vendor-stability signal for a long-term or multi-phase RFP |
| + | Combines analog, FPGA, and firmware disciplines, reducing the number of specialist vendors a procurement team needs to coordinate |
| + | Ultra-low-power design is a named specialty backed by a long history of wearable and biomedical sensor projects |
| + | Small, senior team gives direct engineering access rather than routing through account management layers |
| - | 22 engineers means an RFP requiring several concurrent large workstreams should confirm capacity before committing |
| - | Public case study volume is thinner than its tenure would suggest, so verifying specific past programs needs a direct conversation |
| - | No published pricing or minimum engagement figure |
| 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 |
