Oxalis Design vs Developex: 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.

Developex

Developex was founded in Kyiv, Ukraine in August 2001 and has grown to approximately 255 employees, with a representative office in Canada supplementing its Eastern European delivery base. Its primary stated service is forming software development teams for mobile, cloud, web, and desktop projects, with a second specialization in software for electronic devices covering firmware, drivers, and companion apps. That ordering matters for buyers: firmware capability exists and is real, but it sits behind a larger cross-platform software practice rather than being the firm's lead identity.

Oxalis Design vs Developex: 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
Developex
+ 24 years of operating history with a team that has grown to roughly 255 people across three continents
+ Cross-platform mobile, cloud, web, and desktop capability suits firmware projects that also need a substantial companion application
+ Canadian representative office supplements its Eastern European delivery base for North American client coordination
+ Named second specialization in device firmware and drivers means the capability is deliberate, not accidental
- Firmware and drivers are explicitly the company's second specialization behind its cross-platform software practice, not its lead identity
- No published pricing or minimum engagement figure
- Public case studies specific to firmware projects, versus its broader software portfolio, are limited
