Klika Tech vs Oxalis Design: overview

Klika Tech

Klika Tech was founded in 2013 and is headquartered in North Miami Beach, Florida, with delivery centers across North America, Europe, and Asia, including a Wrocław, Poland office opened in 2021. The company builds IoT, cloud, and embedded product solutions together, holding AWS IoT and DevOps competencies alongside STMicroelectronics partner status on the hardware side, positioning itself for clients whose firmware needs to talk directly to an AWS-based backend from day one. That cloud-first framing distinguishes it from firmware vendors that treat cloud integration as an afterthought handled by a separate team.

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.

Klika Tech vs Oxalis Design: pros and cons

Klika Tech
+ AWS IoT and DevOps competency status backs its cloud-first firmware positioning with a verifiable AWS partner credential
+ STMicroelectronics partner status on the hardware side pairs cloud integration with direct chip-vendor support
+ 12 years of operating history with delivery centers spanning North America, Europe, and Asia
+ Cloud-and-firmware co-design suits products where the backend and the device firmware are built by the same team from the outset
- Its AWS-centric framing is a narrower fit for firmware projects that need to stay cloud-agnostic or target Azure or GCP instead
- Public team size is not published, making capacity harder to gauge against other mid-size firms
- No published pricing or minimum engagement figure
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
