Oxalis Design vs A-listware: 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. The firm's stated scope covers electronics hardware and RF design, embedded software development, and connected-device development for medical, consumer, and industrial clients, from early concept through pilot builds and the transfer to production. As a small, cohesive team focused solely on electronics and embedded firmware rather than a broader product-design or general IT practice, it suits clients who want senior engineers directly on their project rather than layers of account management.

A-listware

A-listware was founded in 2017 and is headquartered in London, UK, with an R&D center in Ukraine and a reported 51 to 200 employees. The company's core model centers on delivering remote engineering teams to clients, with embedded systems and IoT development, including firmware development, legacy system modernization, and hardware integration, named among its service lines. That staff-augmentation framing distinguishes it from project-based firmware consultancies: clients typically embed A-listware engineers into their own team and processes rather than handing off a defined firmware deliverable.

Oxalis Design vs A-listware: pros and cons

Oxalis Design
+ Founded and led directly by two working electronics and software engineers, giving clients direct senior-level involvement
+ Focus on electronics and embedded firmware exclusively, without a broader IT or general software practice diluting attention
+ RF design capability in-house means wireless connectivity work doesn't require a separate specialist vendor
+ Serves medical, consumer, and industrial clients from concept through pilot build and transfer to production
- 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
A-listware
+ Staff augmentation model gives clients direct control over embedded engineers working inside their own existing processes
+ Legacy system modernization is a named specialty, useful for firmware projects centered on an aging codebase rather than greenfield development
+ UK headquarters with a Ukraine R&D center gives Western business hours coordination with Eastern European delivery cost structure
+ 8 years of operating history with a reported 51 to 200 employees
- Firmware development is one line among several IoT and embedded services rather than the company's sole specialty
- Staff augmentation suits clients who already have in-house firmware leadership; it is a narrower fit for a client needing a fully managed project delivery
- No published pricing or minimum engagement figure
