Bluefruit Software vs Capgemini Engineering: overview
Bluefruit Software
Paul Massey started Bluefruit Software in 2000, and it has been employee-owned since 2019. Based in Redruth, Cornwall, it employs 70+ developers, testers and user experience specialists. It works on embedded and device software, often for medical, industrial and scientific products, with a strong emphasis on testing. Hardware design is left to the client or a partner.
Capgemini Engineering
Capgemini Engineering is the result of Capgemini's purchase of Altran, which closed in April 2020. Revelio Labs estimated around 64,700 employees in September 2025, down about 5% on the year. It combines Altran's engineering and R&D services with Capgemini's digital manufacturing work, and analysts pointed to Altran's operational technology skills as the reason for the deal. It is the strongest option here for large, compliance-heavy programmes.
