Oxalis Design vs Promenade Software: overview

Oxalis Design

Oxalis Design is a Bristol, UK electronics and embedded systems consultancy founded by Alex Turner and Alex Thornicroft, both experienced electronics and software engineers who remain personally involved in client work rather than having moved fully into management. For a client evaluating team fit at the smallest scale, this means the people making architecture decisions are the same people who will be reachable throughout the engagement, not a sales contact who hands the work to unnamed staff.

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 founders set out specifically to change how medical device software development works, applying web-framework development speed to a domain that traditionally moves slower while holding to FDA-relevant safety requirements. For a hiring buyer, that's a stated methodology difference, not just a claim of general competence, and its CyberMed·Cloud product line adds a dedicated medical device cybersecurity specialty.

Oxalis Design vs Promenade Software: pros and cons

Oxalis Design
+ Both founders remain personally involved in engineering work, not just business development
+ Focus on electronics and embedded firmware exclusively, without a broader IT practice diluting attention
+ RF design capability in-house means wireless connectivity work doesn't require a separate specialist
+ Serves medical, consumer, and industrial clients from concept through pilot build
- A team of 2 to 10 people limits capacity to a small number of concurrent client programs at any time
- Publicly verifiable founding date and detailed case study history are limited
- No published pricing or minimum engagement figure
Promenade Software
+ Founders explicitly set out to change how medical device software development works, a specific stated methodology rather than generic competence
+ CyberMed·Cloud product line signals dedicated medical device cybersecurity expertise
+ 12 years of operating history focused entirely on medical device software
+ Small team size gives direct access to senior engineers rather than account layers
- Around 11 employees is a small bench for a program requiring multiple concurrent medical device workstreams
- Sole medical-device focus is a narrower fit for hiring needs in unrelated verticals
- No published pricing or minimum engagement figure
