USA Firmware vs Oxalis Design: overview

USA Firmware

USA Firmware was founded in 2011 by Bob Scaccia and operates from Brecksville, Ohio with a small team of around 17 people. Its managed design services combine electrical engineering, firmware, FPGA design, embedded software, and Linux expertise into a single discovery-through-production-enablement process, aimed at clients who want one accountable partner rather than coordinating separate electrical, firmware, and FPGA vendors. Leadership brings a stated 150-plus combined years of experience, concentrated in a small team rather than spread across a large organization.

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.

USA Firmware vs Oxalis Design: pros and cons

USA Firmware
+ Leadership brings a stated 150-plus combined years of experience concentrated in a small, senior team
+ Combines electrical engineering, firmware, and FPGA design under one managed process rather than three separate vendors
+ Discovery-through-production-enablement scope covers the full program, not just firmware coding
+ 14 years of operating history under its founder, Bob Scaccia
- 17 employees is among the smallest teams on this list, limiting concurrent capacity for large programs
- Public case study detail is limited, so verifying past client work requires direct outreach
- 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
