Bluefruit Software vs MistyWest: overview

Bluefruit Software

Testing is the main reason buyers pick Bluefruit Software. The Redruth, Cornwall company has worked on embedded software since 2000, became employee-owned through an Employee Ownership Trust in 2019, and applies a Lean-Agile process with unit tests and test automation built in from the first sprint. It reports work on more than 100 products (per company website; independently unverifiable), with medical devices, scientific instruments and industrial equipment making up much of the portfolio. In 2023 it had about 75 staff and was hiring.

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.
