ByteSnap Design vs RCM Technologies: overview
ByteSnap Design
ByteSnap Design was founded in 2008 by Dunstan Power and Graeme Wintle and operates from Birmingham, UK with roughly 37 employees, with stated plans to grow toward 50. Its engagement scope covers embedded software and firmware design, electronics design, and embedded Linux and Android porting, with wireless protocol coverage spanning ZigBee, LoRa, Wi-Fi, Bluetooth Low Energy, and GSM. For a procurement evaluation comparing bidders on breadth of connectivity support alone, that protocol list is wider than most competing firmware-only vendors can claim.
RCM Technologies
RCM Technologies was founded in 1971 and is headquartered in Pennsauken, New Jersey, with 4,930 total employees across its full business. Its Aerospace & Defense division brings over 50 years of product lifecycle engineering experience, with embedded systems work covering mission and safety-critical software development, verification and validation up to DAL-A standards, and manufacturing and supply chain engineering. For a defense or aerospace RFP requiring DAL-A verification and validation experience, that specific certification level narrows the field of qualified bidders considerably.
