Sigma Software Group vs Netguru: overview

Sigma Software Group

Sigma Software Group was founded in 2002 and is headquartered in Stockholm, Sweden, with more than 2,100 professionals across 40 offices in 19 countries. Its AI practice spans AI-assisted development through agentic task execution in well-bounded modules, emphasizing quality and predictability in real production codebases. As a Swedish-headquartered EU company, it offers a strong Nordic data-residency option, while its wide multi-country office footprint gives European buyers additional choice on delivery jurisdiction.

Netguru

Netguru is a digital product consultancy founded in 2008 and headquartered in Poznań, Poland, with approximately 440–450 employees delivering product design, engineering, and AI/agentic development services.
