Euristiq vs Tallium: overview

Euristiq

Euristiq's Warsaw office keeps the company inside the EU's GDPR framework directly, useful for a UK buyer's data-processing terms, one part of a commercial footprint that also reaches Toronto alongside its Lviv engineering base since launching in 2016. The company is one of the newer firms on this list, with a shorter multi-year track record than the decades-old companies elsewhere in this review. Its public work spans general product development rather than one named vertical.

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.
