Barr Group vs Voler Systems: overview
Barr Group
Barr Group was founded in 2012 and is headquartered in Gaithersburg, Maryland, with a team in the 51 to 200 employee range. Led by CTO Michael Barr, a former editor-in-chief of Embedded Systems Design magazine and author of multiple embedded software books, the firm's identity centers on independent training, firmware process and architecture consulting, and legal and corporate technical expert-witness work rather than volume development. That positioning, expertise as the product rather than headcount as the product, is what a consulting-first buyer is specifically looking for when the engagement is advisory rather than build-and-ship.
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.

Barr Group vs Voler Systems: pros and cons
| Barr Group | |
|---|---|
| + | Led by Michael Barr, a widely recognized embedded software authority and published author, giving the firm's advisory opinion real external credibility |
| + | Training and expert-witness services are core, established business lines, not a marketing add-on to a dev-shop offering |
| + | 13 years of operating history built specifically around advisory and process-improvement work |
| + | 51 to 200 employees give enough bench depth for concurrent training and consulting engagements without positioning as a large build shop |
| - | Volume development capacity is not the firm's stated focus, so a buyer needing a large parallel build program may need a second vendor |
| - | No published consulting rate or minimum engagement figure |
| - | Legal expert-witness work is a distinct service line from product consulting; confirm which practice area an inquiry is routed to |
| 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 |
