Voler Systems vs Sigma Design: overview
Voler Systems
Voler Systems has operated from Sunnyvale, California since 1979, a 46-year track record, with a current team of roughly 22 engineers. The firm combines analog circuit design, FPGA programming, and embedded firmware, and its long operating history means it is frequently brought in for early feasibility and architecture assessment on ultra-low-power wearable and biomedical sensor products before a client commits to full development. For a buyer evaluating a consulting relationship on longevity as a risk factor, 46 years of continuous operation is one of the strongest signals on this list.
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 advisory scope covers mechanical design, industrial design, testing, and software and firmware engineering, positioning itself as a full product design and engineering partner rather than a firmware-only consultant. For an architecture review that needs to weigh industrial design, mechanical engineering, and firmware decisions together, Sigma Design's breadth and headcount give it more parallel-program capacity than most boutique advisory firms.

Voler Systems vs Sigma Design: pros and cons
| Voler Systems | |
|---|---|
| + | 46 years of continuous operation is one of the strongest vendor-longevity signals for a long-term advisory relationship on this list |
| + | Combines analog, FPGA, and firmware disciplines, useful for feasibility questions spanning multiple engineering domains |
| + | Ultra-low-power design expertise, built over decades, suits early architecture decisions for battery-constrained products |
| + | Small, senior team gives direct access to experienced engineers rather than junior staff during a feasibility phase |
| - | 22 engineers means a large concurrent advisory-plus-build program should confirm capacity before committing |
| - | Public case study volume is thinner than its tenure would suggest, so verifying specific feasibility engagements needs a direct conversation |
| - | No published consulting rate or minimum engagement figure |
| Sigma Design | |
|---|---|
| + | 283 employees across five continents give substantially more parallel-program advisory capacity than most boutique firms |
| + | 31 years of operating history under continuous product-design focus |
| + | Industrial design and mechanical engineering advisory sits alongside firmware, matching multi-discipline architecture reviews |
| + | Onsite contracting option can place advisory engineers directly with a client team |
| - | Firmware advisory 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 advisory engagements, versus its broader product design portfolio, are limited |
