Endava vs N-iX: overview

Endava

Endava is the largest UK-headquartered company on this list built around nearshore delivery. It reported 11,479 staff at the end of June 2025, and the UK supplied 33% of revenue in the final quarter of that fiscal year. Delivery centres in Romania, Moldova, North Macedonia, Serbia, Bulgaria, Argentina and elsewhere let it staff large programmes at below-London cost. Headcount fell from 12,085 a year earlier, which reflects softer demand across the IT services market.

N-iX

N-iX started in Lviv in 2002 as Novellix, building applications for Novell's Linux platform, and Novell became its first large client. It now reports more than 2,400 engineers in Ukraine, Poland and other countries. In the UK it trades through N-iX Technologies Limited, registered in London in 2022, though public sources do not show a staffed UK delivery office. It suits buyers who want a large Central and Eastern European engineering pool and are comfortable managing it remotely.
