ELEKS vs Tallium: overview

ELEKS

Lviv sits one to two hours ahead of UK time depending on the season, close enough for a full overlapping working day, which matters for ELEKS specifically given the company has been running continuously from there since 1991, a year before Ukraine declared independence. That three-and-a-half-decade history has produced a deep healthcare, insurance, and fintech track record and a stable, senior-heavy delivery process. Its public positioning leans on decades of history more than any single sharp technical specialty.

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.
