Sigma Software vs Capgemini Engineering: overview
Sigma Software
Sigma Software was founded in 2002 and is part of the Swedish Sigma group. It describes a team of over 2,100 professionals in offices across 19 countries. Embedded and automotive software are among its practices, alongside a wide range of web, cloud and enterprise work. IoT buyers will find capable firmware and cloud engineers, but not a hardware design house.
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.
