Endava vs Sigma Software Group: 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.

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.
