10Clouds vs Tallium: overview

10Clouds

10Clouds was founded in Warsaw, Poland in 2009 and has built a reputation for strong design culture layered onto mobile-first product development, serving international clients including UK businesses. Its EU headquarters gives it the same straightforward GDPR posture as its Polish peers on this list, useful for a UK buyer's data-processing agreements. Public information on its current team size is thinner than for some peers, so buyers should confirm current capacity directly.

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.
