Oxalis Design vs Instinctools: 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. 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.

Instinctools

Instinctools was founded in 2000 by Alexey Spas and Diethard Sohn, with a US headquarters in Potomac, Maryland and a European headquarters in Stuttgart, Germany, and reports between roughly 350 and 500 employees across development centers in Poland, India, and Kazakhstan. The company's primary identity is enterprise software development, with embedded systems and IoT firmware work positioned as one applied domain among cloud, data, and enterprise IT modernization services for Fortune 500 clients. That framing suits organizations whose firmware need is embedded inside a larger enterprise IT modernization program rather than a standalone hardware product launch.

- 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
Instinctools
+ 25 years of operating history under its original two founders
+ Fortune 500 client relationships indicate experience navigating large-enterprise procurement and compliance processes
+ Development centers across Poland, India, and Kazakhstan give broad delivery capacity and cost flexibility
+ Embedded and IoT work is positioned inside a larger cloud and enterprise-modernization practice, useful when firmware is one part of a bigger program
- Firmware and embedded systems are a secondary applied domain, not the company's primary identity or deepest bench
- No published pricing or minimum engagement figure
- Reported employee counts vary across sources between roughly 350 and 500, making exact current capacity harder to pin down
