Endava vs Zühlke: 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.

Zühlke

Zühlke was founded in Switzerland in 1968 and employs close to 2,000 people, with nearshore centres in Serbia, Bulgaria, Portugal and Vietnam. The UK business marked 25 years in 2025 and has nearly 150 staff across London, Manchester and Edinburgh, led by UK CEO Angela Bishop since October 2024. UK clients include HSBC and NHS England. Its medical-device and regulated-industry engineering background is unusual for a services firm of this size.
