ByteSnap Design vs Promenade Software: 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.

Promenade Software

Promenade Software was founded in 2013 and is headquartered in Irvine, California with a small team, most recently reported around 11 employees. The firm built its practice specifically to accelerate embedded medical device software development while holding to FDA-relevant safety-critical requirements, applying web-framework concepts to a domain that traditionally moves slower. Regulatory-compliance certifications and a CyberMed·Cloud product line targeted at medical device security give it a specific credential set relevant to a medical device RFP beyond general firmware capability.

+ Embedded Linux and Android porting experience covers higher-complexity connected products beyond bare-metal MCU work
- 37 employees, growing toward 50, is smaller than firms bidding on the largest connected-device programs
- No published pricing or minimum engagement threshold
- Some wireless protocol claims are per company website and independently unverifiable beyond that source
Promenade Software
+ Development approach specifically targets faster iteration within FDA-relevant safety-critical constraints, a stated differentiator against slower-moving medical firmware vendors
+ CyberMed·Cloud product line signals dedicated medical device cybersecurity expertise beyond general firmware work
+ 12 years of operating history focused entirely on medical device software
+ Small team size gives an RFP evaluator direct access to senior engineers during technical evaluation
- Around 11 employees is a small bench for an RFP requiring multiple concurrent medical device programs
- Sole medical-device focus is a narrower fit for an RFP spanning non-medical hardware categories
- No published pricing or minimum engagement figure
