Ciklum vs Sigma Software Group: overview
Ciklum
Ciklum's legal headquarters moved from Kyiv to London some years after its 2002 founding, which is unusual on a UK-facing list: most outsourcing companies serving British clients are headquartered elsewhere and simply sell into the UK market. Its roughly 3,900-person team still delivers primarily from Ukraine, spanning full-lifecycle product engineering across cloud, data, and digital work for enterprise clients. That London incorporation gives UK buyers a domestic contracting entity, something several peers on this list, however strong their engineering, simply cannot offer.
Sigma Software Group
Five friends founded Sigma Software Group in Kharkiv in 2002; the company has since scaled to more than 2,100 professionals across roughly 40 offices worldwide, with its post-2022 expansion adding real Western European delivery presence alongside its original Ukrainian base. Named practices in aerospace, gaming, fintech, and automotive engineering give it a technical-consulting positioning UK buyers evaluating a specific vertical need can lean on. That same expansion means a buyer specifically wanting Ukraine-concentrated delivery should verify current team location directly.
