Byte Lab vs Integra Sources: 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.
Integra Sources
Two hardware and software engineers set up Integra Sources in 2014, and it now operates from Astana, Kazakhstan with a team in the low dozens. Its service list covers electronics design, embedded firmware, Linux kernel and driver development, computer vision and robotics, and it has collected a long run of Clutch reviews for IoT and device projects. Rates are below those of the European and US firms on this list. Buyers get engineers comfortable at the register level, though with less of the process documentation that regulated industries expect.

Byte Lab vs Integra Sources: pros and cons
| 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 |
| Integra Sources | |
|---|---|
| + | Kernel module and device driver work is a stated speciality |
| + | Rates make it one of the more affordable options for low-level engineering |
| + | Can take a product from schematic through firmware for small hardware startups |
| - | Small team with limited capacity for parallel projects |
| - | Little public evidence of IEC 62304, ISO 26262 or similar regulated development |
| - | Time-zone gap with North American clients |
