Byte Lab vs Very: 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.

Very

Very is a US IoT engineering firm that grew out of a design and development agency founded in 2011 and now works as a distributed team, with its earlier base in Chattanooga, Tennessee. Directory listings put its size at 51 to 200 people. It builds IoT products across hardware engineering, firmware, mobile apps and data, and it hired a co-author of the Nerves project, which runs Elixir on embedded Linux. Reviews mention hardware, firmware, React Native and AI feature work, so firmware is one part of a broader product offer.

Byte Lab vs Very: 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
Very
+ Combines product strategy, design and engineering for teams new to hardware
+ Nerves experience is rare and useful for Elixir-based device software
+ Delivers the device, app and data platform together
- Firmware is one part of a product agency offer
- US rates without a lower-cost offshore option
- Office location and headcount details vary between sources
