Voler Systems vs Promwad: 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.
Promwad
Promwad was founded in 2004 by Roman Pakholkov and is headquartered in Essen, Germany with roughly 146 employees across Europe, North America, and Asia. Its advisory work bundles embedded software architecture, hardware design, and PCB layout guidance, with ASIL-C functional-safety experience in automotive infotainment and ECU development alongside telecom, digital TV, and industrial automation consulting. For an automotive or safety-relevant architecture review, ASIL-C is a checkable credential rather than a general safety claim.
