Conclusive Engineering vs Oxalis Design: overview

Conclusive Engineering

Conclusive Engineering was founded in 2018 by Jakub Klama and Wojciech Kloska in Katowice, Poland, and has grown to a team most sources place between 30 and 50 engineers. The company works across the embedded stack, from bootloader and RTOS architecture through embedded Linux and FreeBSD systems, with named clients in automotive and healthcare where ISO 26262 and IEC 61508 alignment matters. It is also a listed Nordic Semiconductor and Texas Instruments partner, giving it direct access to chip-level support on those platforms rather than working purely from public datasheets.

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.

Conclusive Engineering vs Oxalis Design: pros and cons

Conclusive Engineering
+ Nordic Semiconductor and Texas Instruments partner listings give direct chip-vendor support channels rather than public-datasheet-only development
+ FreeBSD expertise is uncommon among firmware vendors, most of whom default to Linux or bare-metal only
+ ISO 26262 and IEC 61508 alignment work suits safety-relevant automotive and industrial clients
+ Founder-led team formed specifically around embedded systems rather than growing out of a general software house
- Team size estimates vary by source between roughly 30 and 50 people, capping concurrent large-program capacity
- Founded in 2018, so its public track record is shorter than firms with 15 to 25 years of delivery history
- No published pricing or minimum engagement threshold
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
