Cognizant vs Sigma Software Group: overview
Cognizant
Cognizant started in 1994 in Chennai, India as an in-house technology unit inside Dun & Bradstreet, and today runs out of Teaneck, New Jersey with roughly 349,800 employees. It now brands itself an AI Builder, positioned as the bridge between AI investment and enterprise value, a deliberate shift from its older IT-outsourcing identity, even though the underlying delivery model and scale still read as a large IT services firm rather than a boutique AI agency.
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 sitting as one specialty among several. A Nordic base gives EU clients a Scandinavian legal entity to contract with, distinct from the Central and Eastern European base most peers use.
