Byte Lab vs Sirin Software: 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.

Sirin Software

Sirin Software is registered in Florida, but its engineering happens at R&D offices in Kyiv and Ivano-Frankivsk. The company dates from 2014 and focuses on embedded Linux, firmware and IoT device software, with directory headcount estimates between roughly 25 and 50. Clutch reviews describe board bring-up, driver development and IoT gateway projects for US and European hardware companies. For buyers who want a US contracting entity and Ukrainian engineering rates, it is one of the more direct options here.

Byte Lab vs Sirin Software: 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
Sirin Software
+ Embedded Linux, Yocto and Buildroot work is the core of its portfolio
+ US entity simplifies contracts for American buyers
+ Rates closer to Eastern European than US levels
- Directory headcount estimates vary widely, so confirm team size and seniority up front
- No in-house hardware design
- Delivery depends on engineers based in Ukraine, which some buyers will want covered in continuity planning
