Perfectial vs Tallium: overview

Perfectial

Access to a wider European client network, including UK relationships built through Avenga's own footprint, is what Perfectial gained when the German group acquired it in 2021, a decade after the company's 2010 founding in Lviv. That came at the cost of the fully independent ownership a buyer might otherwise assume from its Ukrainian origins; the roughly 450-person team itself still centers its engineering practice on product development and long-term dedicated teams rather than short-term staffing.

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.
