Bluefruit Software vs Elinext: 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.

Elinext

Elinext was founded in 1997 by Dr. Khoa Nguyen and now reports about 700 employees, with delivery centres in Poland, Georgia, Kazakhstan, Vietnam and Uzbekistan. Sources disagree on its headquarters (Warsaw and Syosset, New York both appear); this review uses Warsaw. Embedded software development and IoT are listed services, and one client testimonial describes firmware for transferring data between sensors and a user interface. Most of its business is enterprise, web and mobile development, which makes it a generalist pick for firmware.
