Byte Lab vs Developex: overview
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.
Developex
Developex has written software for hardware companies since 2001, and its client list leans toward consumer electronics and peripheral makers who need firmware, drivers and the desktop or mobile utilities that configure their devices. The company is based in Kyiv with offices listed in Munich, Kraków and Zagreb, and directory estimates put the team at about 250 to 350 people. A company blog post put its embedded group at more than 30 developers (per company website; independently unverifiable). That makes firmware a real practice inside a larger custom-software business.

| + | 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 |
| Developex | |
|---|---|
| + | Long experience with USB peripherals, audio devices and their PC utilities |
| + | Can staff firmware, drivers and desktop apps from a single team |
| + | Eastern European rates |
| - | Embedded is a minority of the business, so check engineers' firmware track records |
| - | No hardware design |
| - | Ukrainian delivery base may require continuity planning for some buyers |
