ByteSnap Design vs Intellias: 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.

Intellias

Intellias was started in Lviv in 2002 and has grown into one of Ukraine's largest software engineering employers, with several thousand staff. Its strongest embedded-adjacent work is in automotive: in-vehicle software, navigation and maps (it has a long partnership with HERE Technologies), and software-defined vehicle projects for OEMs and Tier 1 suppliers. Client names cited include HERE, TomTom, Elmos and JOYNEXT. It is a reasonable choice for automotive application and middleware layers, and a less obvious one for bare-metal MCU firmware.
