Sigma Software Group vs Ciklum: overview

Sigma Software Group

Five friends, four programmers and a lawyer, started Sigma Software Group in Kharkiv in 2002. More than two decades later the company runs roughly 40 offices across 19 countries with over 2,100 engineers, building software for aerospace, gaming, fintech, and automotive clients under named domain practices rather than one generic development service. Its post-2022 expansion has shifted a real share of delivery capacity outside Ukraine, so a buyer who specifically wants Ukraine-based engineers should confirm current team location.

Ciklum

London is where Ciklum's legal paperwork lives now, even though its engineering roots and a large share of its roughly 3,900-person team trace back to a 2002 founding in Kyiv. The company builds software across cloud, data, and digital work at a scale closer to SoftServe or GlobalLogic than to the mid-size studios elsewhere on this list, and it has broadened its skill footprint through acquisitions over the years. A buyer who cares specifically about Ukraine-headquartered status, versus Ukraine-staffed only, should confirm the current corporate structure directly.
