ByteSnap Design vs Punch Through: 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.

Punch Through

Few firms go as deep on Bluetooth LE as Punch Through. The Minnesota company was founded in 2009 by Colin Karpfinger and employs somewhere between 11 and 50 people according to directory listings. It builds connected products where the radio link is the hard part: device firmware on Nordic, Silicon Labs and TI chips, plus the iOS and Android apps that pair with them. Its public guides on BLE throughput, pairing and power use are widely read by embedded engineers. A large share of its client work is medical and consumer health devices.
