Sigma Software Group vs Tallium: 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.
Tallium
Every other company on this UK-facing list quotes engagements privately; Tallium, founded in Kyiv in 2012, simply posts its rate on GoodFirms instead: $25-$49 per hour, backed by a 5.0-star rating across more than 40 verified reviews. That transparency makes genuine cost comparison possible before a first call, a real advantage for a UK buyer sizing up a budget before committing to a discovery process. Its boutique scale suits single-team engagements rather than the multi-hundred-person programs a firm like SoftServe or Ciklum can staff.
