SoftServe vs Sigma Software Group: overview

SoftServe

SoftServe was founded in 1993 in Lviv, Ukraine, and now operates with dual headquarters in Lviv and Austin, Texas, with more than 10,000 employees. Its three-decade data, cloud, and Microsoft-centric digital transformation practice has built out a dedicated generative AI practice with particular depth in healthcare. Its Ukrainian origin means it sits outside the EU proper, though its European delivery centers (including EU member states) give it meaningful EU-adjacent capacity for buyers comfortable with a Ukraine-founded, dual-HQ structure.

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.
