Integra Sources vs Mistral Solutions: overview
Integra Sources
Two hardware and software engineers set up Integra Sources in 2014, and it now operates from Astana, Kazakhstan with a team in the low dozens. Its service list covers electronics design, embedded firmware, Linux kernel and driver development, computer vision and robotics, and it has collected a long run of Clutch reviews for IoT and device projects. Rates are below those of the European and US firms on this list. Buyers get engineers comfortable at the register level, though with less of the process documentation that regulated industries expect.
Mistral Solutions
Anees Ahmed and Rajeev Ramachandra started Mistral Solutions in Bengaluru in 1997, and it has grown into one of India's better-known embedded design houses, with 300 or more staff at the time of its acquisition. AXISCADES Technologies announced the purchase in 2017 and completed it in December 2022 for Rs 296 crore. Mistral designs boards, writes BSPs and firmware, and builds rugged systems, with defence and aerospace programmes as its largest market. It is a long-time Texas Instruments design partner.
