Sigma Software Group vs Tallium: 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.
Tallium
A published hourly rate is what sets Tallium apart on this list: $25-$49 per hour per GoodFirms, backed by a 5.0-star rating across more than 40 verified reviews, out of a company founded in Kyiv in 2012. That published rate is unusual among the companies reviewed here, most of which don't disclose pricing publicly, and it makes Tallium a genuine cost-transparency option for smaller buyers. Its boutique scale suits single-team engagements better than very large, multi-team enterprise programs.
