Promwad vs Byte Lab: overview
Promwad
Roman Pakholkov started Promwad in Minsk in 2004 to design mass-produced electronics on system-on-chip platforms, and the company has since moved its business into the EU, with headquarters in Essen, Germany and a client delivery office in Lithuania. It reports more than 100 employees across 15 countries (per company website; independently unverifiable) and over 500 completed projects. Work spans schematic and PCB design, FPGA logic, embedded Linux, RTOS firmware and preparing designs for factory production. Broadcast video, telecom, automotive and industrial automation are its most frequently cited sectors.
Byte Lab
Byte Lab began in Zagreb in 2011 and has grown into a group of roughly 150 people with offices in Croatia and Austria (per company website; independently unverifiable). It is a design partner for both STMicroelectronics and Nordic Semiconductor, and its services include embedded hardware design, firmware and embedded software development, GUI work and low-volume manufacturing. That last point is unusual among firmware vendors: a client can receive working boards in small quantities from the same company that wrote the code. Clutch reviews describe IoT, industrial and consumer device projects.

Promwad vs Byte Lab: pros and cons
| Promwad | |
|---|---|
| + | FPGA and firmware engineers work in the same team, which helps on video and high-speed interface products |
| + | Design-for-manufacturing experience reduces surprises when a prototype moves to a contract manufacturer |
| + | Twenty years of shipped products gives it a long reference list across telecom and broadcast |
| + | Contracting through EU entities simplifies procurement for European buyers |
| - | Founded in Belarus and relocated to the EU; some buyers will want to confirm where their engineers are actually based |
| - | Headcount figures vary by source, so ask who will be assigned before signing |
| - | Pure firmware jobs without a hardware component are a smaller share of its portfolio |
| Byte Lab | |
|---|---|
| + | Low-volume production lets a startup get pilot units without finding a separate manufacturer |
| + | Design partner status with ST and Nordic covers the two MCU families most IoT products use |
| + | Croatian base means EU contracts and rates below Western European design houses |
| + | GUI work on LVGL and TouchGFX suits products with small touch displays |
| - | Low-volume manufacturing stops well short of mass production, so a contract manufacturer is still needed later |
| - | Less public material on regulated medical or automotive safety projects than larger firms |
