Sigma Software Group vs Jelvix: overview
Sigma Software Group
Five friends started Sigma Software Group in Kharkiv in 2002; the company now runs roughly 40 offices across 19 countries with more than 2,100 professionals. It runs practices across gaming, aerospace, fintech, and automotive engineering, positioning itself as a technology consulting and product development partner rather than a pure staffing vendor. The company's own relocation and expansion since the 2022 full-scale invasion has moved a meaningful share of delivery capacity outside Ukraine, which buyers who specifically want Ukraine-based delivery should confirm directly.
Jelvix
Jelvix lists headquarters across four cities at once, Tallinn, Kharkiv, Stuttgart, and London, an unusually distributed structure for a company founded in 2011. It positions itself as a general custom software and staff-augmentation vendor for mid-size businesses, with case studies leaning toward standard web and enterprise application work rather than a named technical specialization. That distributed footprint can make it harder for a buyer to pin down which legal entity they would actually be contracting with, worth confirming directly before signing.
