Capgemini Invent vs Sigma Software Group: overview
Capgemini Invent
Capgemini Invent launched in 2018 out of Paris as the digital innovation, consulting, and transformation brand of the wider Capgemini Group, and it now employs somewhere between roughly 17,000 and 18,000-plus people across six continents depending on the source. It combines strategy work with data science and design under a single brand, treating AI as a component of digital transformation rather than isolating it as its own standalone practice.
Sigma Software Group
Sigma Software Group was founded in 2002 and is headquartered in Stockholm, Sweden, with a reported headcount between 1,001 and 5,000 employees. The group covers Java and .NET development, web and mobile development, and general software delivery, with AI advisory functioning as one specialty among several. Its Nordic base is what stands out: most comparable agencies on this list run through a Central or Eastern European legal entity, and Sigma gives EU clients a genuinely Scandinavian alternative.
