Voler Systems vs Integra Sources: 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.
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.

Voler Systems vs Integra Sources: 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 |
| 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 |
