Integra Sources vs MistyWest: 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.

MistyWest

MistyWest is a Vancouver engineering consultancy that has worked on hardware, firmware and mechanical design for deep-tech companies since about 2010. Directory estimates put the team between 20 and 100 people, and it regularly hires contract firmware engineers for specific projects. Its sweet spot is early-stage hardware: proof-of-concept boards, battery-powered connected devices and robotics, carried through to designs a factory can build. Firmware is part of that product-development package rather than a standalone service line.
