Sigma Software Group vs Trinetix: overview

Sigma Software Group

Five friends founded Sigma Software Group in Kharkiv in 2002; the company has since scaled to more than 2,100 professionals across roughly 40 offices worldwide, with its post-2022 expansion adding real Western European delivery presence alongside its original Ukrainian base. Named practices in aerospace, gaming, fintech, and automotive engineering give it a technical-consulting positioning UK buyers evaluating a specific vertical need can lean on. That same expansion means a buyer specifically wanting Ukraine-concentrated delivery should verify current team location directly.

Trinetix

Several of Trinetix's European delivery offices, Poland among them, sit comfortably inside UK working-hours range, part of a footprint that has grown quickly since a $10 million investment round in 2023 funded a new Argentina hub and a corporate office move to Nashville, Tennessee. The company itself dates back to 2011 in Kyiv and now runs roughly 1,200 engineers across Ukraine, Poland, Argentina, and additional offices in Spain, Portugal, Germany, Bulgaria, and Romania. Its recent, rapid expansion means less multi-year track record in the newer locations specifically than in its original Ukrainian base.
