DataArt vs Thoughtworks: overview

DataArt

Eugene Goland founded DataArt in New York in 1997, and the company opened in London in 2001. It reports more than 6,000 people as of September 2025, spread across Central and Eastern Europe, Latin America and elsewhere. Travel and hospitality, finance and healthcare are its strongest industries. UK clients get a long-standing London presence with delivery from lower-cost locations.

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.
