Oxalis Design vs Blue Sparq: 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 who remain personally involved in client work rather than having moved fully into management. For a client evaluating team fit at the smallest scale, this means the people making architecture decisions are the same people who will be reachable throughout the engagement, not a sales contact who hands the work to unnamed staff.
Blue Sparq
Blue Sparq was founded in 2008 and is headquartered in Cape Coral, Florida with 20 employees. The firm's stated specialization in control system design and manufacturing means engineers on staff have specifically worked the intersection of firmware and physical mechanism control, a narrower skill set than general embedded firmware alone. For a hiring buyer building a product with real physical actuation, that concentrated experience is worth more than a generalist team's broader claims.
