Ciklum vs Romexsoft: overview

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.

Romexsoft

Cloud-native application development on AWS is where Romexsoft has built its actual engineering credibility, holding AWS Certified Consulting Partner status out of a company founded in Lviv in 2004, with representative offices in London and Chicago. That certification is a verifiable signal a buyer can check directly, unlike a plain marketing claim of cloud expertise. Two decades of operating history give the company a mature development process, though it doesn't have one single named industry vertical beyond its cloud specialization.
