ByteSnap Design vs Integra Sources: overview

ByteSnap Design

Graeme Wintle and Dunstan Power founded ByteSnap Design in Birmingham in 2008, and both still run it from Park Point in Longbridge. With about 40 people, it is small by the standards of this list but covers a wide technical spread: schematic and PCB design, embedded Linux and Android board bring-up, RTOS firmware and touch interfaces. It is a Silicon Labs certified design partner and an Analog Devices partner. Trade press has linked recent growth to medical device work, alongside EV charging and industrial clients.

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.
