N-iX vs Tallium: overview

N-iX

N-iX was founded in Lviv in 2002 and has grown to more than 2,000 professionals spread across eight countries, Poland, Ukraine, Sweden, Bulgaria, Malta, the UK, the US, and Colombia, giving it a genuine UK presence rather than a purely offshore sales relationship. Its practice spans custom software, cloud, and data engineering for enterprise clients, with the multi-country footprint offering real delivery-risk diversification a single-country vendor can't match. That spread is a real advantage for a UK buyer wary of concentrating delivery risk in one location.

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.
