Lemberg Solutions vs Voler Systems: overview

Lemberg Solutions

Lemberg Solutions was founded in Lviv in 2007 and has grown to a 200+ person team with additional offices in Hamburg, London, and Kraków. Its firmware practice covers RTOS and bare-metal architecture on FreeRTOS, Zephyr, and Azure RTOS, secure boot and OTA update design, MCU and platform migration, and embedded GUI work in Qt, LVGL, and TouchGFX, backed by direct partnership status with NXP, STMicroelectronics, and Microchip. An in-house lab with oscilloscopes, evaluation kits, and hardware-in-the-loop testing lets the team validate board bring-up rather than outsource it. ISO 9001, ISO 27001, and ISO 13485 certifications, plus MISRA-aware testing, support regulated healthcare, automotive, and industrial clients, and the company transfers full IP and source code rights to the client on delivery.

Voler Systems

Voler Systems has operated out of Sunnyvale, California since 1979, making it one of the longest-running independent electronic design consultancies still active in the niche, with a team of roughly 22 engineers today. The firm pairs analog circuit design and FPGA programming with embedded firmware, and its wearable device work leans specifically on ultra-low-power system design, sensor integration, and wireless transmission, the constraints that separate battery-powered wearables from mains-powered embedded products. It also does biomedical sensor and regulatory-support work for medical wearables, an area that draws on both its electronics and firmware disciplines together.

Lemberg Solutions vs Voler Systems: pros and cons

Lemberg Solutions
+ Direct partner status with NXP, STMicroelectronics, and Microchip gives chip-level support most firmware vendors have to route through a distributor
+ In-house lab with oscilloscopes, evaluation kits, and HIL testing covers board bring-up work that many pure-software firms outsource
+ ISO 27001, ISO 9001, and ISO 13485 certifications plus MISRA-aware testing fit regulated medical and industrial clients
+ Embedded GUI capability across Qt, LVGL, and TouchGFX is broader than most competitors that only support one framework
+ Full IP and source code rights transfer to the client on every engagement
- Does not run mass production in-house, so device manufacturing still requires a separate partner
- Does not handle regulatory certification submissions on the client's behalf, only the supporting technical documentation
- No published minimum engagement figure, so smaller teams need a scoping call before knowing if budget fits
Voler Systems
+ 46 years of operating history is unusually long for an independent firmware and electronics design house
+ Ultra-low-power design is a stated specialty, not a general capability applied to a battery-powered project after the fact
+ FPGA programming alongside firmware covers projects that need custom logic as well as MCU code
+ Biomedical sensor and wearable regulatory-support experience spans both hardware and firmware sides of a project
- 22 engineers limits the firm to a small number of concurrent client programs at any time
- Public case study volume is lower than larger firmware consultancies, so verifying specific past projects requires a direct conversation
- No published pricing or minimum engagement figure
