DataRoot Labs vs Sigma Software Group: overview
DataRoot Labs
Kyiv is home base for DataRoot Labs, founded in 2016 with a stated focus on applied data science research rather than broad IT outsourcing. Sources disagree on staff size, some citing as few as 11 employees and others closer to 200, likely reflecting how contractor networks get counted differently across platforms. What stays consistent across sources is the firm's specialization: machine learning models, computer vision pipelines, and hands-on AI R&D for startups that need research capability without building an internal team from scratch.
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 solutions development as one of several listed specialties rather than a founding focus. Its Nordic base and enterprise scale make it a fit for buyers who want AI paired with broader software engineering under one European vendor.
