Endava vs Thoughtworks: 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.

Thoughtworks

Thoughtworks was founded in Chicago in 1993 and has had a significant UK presence for decades. Apax Partners took it private in a deal valued at about $1.75bn that closed in late 2024, after a NASDAQ listing in 2021, and the transaction came with job cuts affecting about 6–7% of its 10,500 staff. It is known for its Technology Radar and for shaping agile and continuous-delivery practice. It has delivery centres in India, China, Brazil and elsewhere, but UK engagements usually lean on senior onshore consultants.
