Endava vs Tallium: overview

Endava

Endava was founded in London in 2000 and remains headquartered there today, now listed on the New York Stock Exchange, with roughly 11,300 employees delivering primarily out of Central and Eastern European centers. That combination, UK incorporation with public-company financial transparency, is genuinely rare among the companies serving British buyers on this list. Named practices in payments, banking, and insurance technology give it real depth in the financial services sector UK buyers frequently need.

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.
