Witekio vs Oxalis Design: overview

Witekio

Witekio began as Adeneo Embedded, founded in Lyon, France in 2001, and rebranded to Witekio as it grew its embedded Linux and IoT software practice across Europe and North America. Avnet, a global electronics distributor, acquired the company in September 2019 to add embedded software depth to its IoT hardware distribution business, and Witekio now operates as an Avnet subsidiary rather than an independent firm. Its services span firmware development, embedded Linux implementation, and secure boot, encryption, and OTA update mechanisms, and the Avnet relationship can simplify sourcing when a client also needs component distribution alongside software.

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.

Witekio vs Oxalis Design: pros and cons

Witekio
+ 24 years of operating history under the Adeneo Embedded and Witekio names, with continuous focus on embedded Linux and IoT software
+ Secure boot, encryption, and OTA update implementation is a stated core capability, not a bolt-on service
+ Avnet ownership since 2019 connects software delivery to component sourcing and distribution
+ European and North American office presence gives broader timezone coverage than a single-region firm
- Ownership by Avnet, a component distributor, since 2019 means Witekio no longer operates as an independent consultancy
- No published minimum engagement figure or pricing structure
- Public team size figures are inconsistent across sources, making current headcount harder to verify precisely
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
