Voler Systems vs Oxalis Design: overview
Voler Systems
Voler Systems has operated from Sunnyvale, California since 1979, a 46-year run that means most of its roughly 22 engineers have deep, overlapping tenure rather than a constantly rotating bench. The firm combines analog circuit design, FPGA programming, and embedded firmware, with a specific focus on ultra-low-power wearable and biomedical sensor products. For a client evaluating team stability, a firm that has retained its identity and core expertise for over four decades signals something different than a firm assembled quickly to staff up for a hiring surge.
Oxalis Design
Oxalis Design is a Bristol, UK electronics and embedded systems consultancy founded by Alex Turner and Alex Thornicroft, both experienced electronics and software engineers who remain personally involved in client work rather than having moved fully into management. For a client evaluating team fit at the smallest scale, this means the people making architecture decisions are the same people who will be reachable throughout the engagement, not a sales contact who hands the work to unnamed staff.

Voler Systems vs Oxalis Design: pros and cons
| Voler Systems | |
|---|---|
| + | 46 years of continuous operation suggests a team with deep institutional knowledge, not high turnover |
| + | Combines analog, FPGA, and firmware disciplines in one small team, reducing the number of specialists a client has to coordinate |
| + | Ultra-low-power design expertise built up over decades of the same core focus area |
| + | 22-person size means direct access to senior engineers, not junior staff routed through a larger organization |
| - | 22 engineers means a client needing several concurrent teams should confirm capacity before committing |
| - | Public case study volume is thinner than its tenure would suggest, worth a direct reference conversation |
| - | No published pricing or minimum engagement figure |
| Oxalis Design | |
|---|---|
| + | Both founders remain personally involved in engineering work, not just business development |
| + | Focus on electronics and embedded firmware exclusively, without a broader IT practice diluting attention |
| + | RF design capability in-house means wireless connectivity work doesn't require a separate specialist |
| + | Serves medical, consumer, and industrial clients from concept through pilot build |
| - | A team of 2 to 10 people limits capacity to a small number of concurrent client programs at any time |
| - | Publicly verifiable founding date and detailed case study history are limited |
| - | No published pricing or minimum engagement figure |
