ByteSnap Design vs Very: 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.

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.
