Thoughtworks vs EPAM Systems: overview
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.
EPAM Systems
EPAM Systems was founded in 1993 and is headquartered in Newtown, Pennsylvania. It reported more than 62,750 employees in Q1 2026. In the UK it has offices in London and Newcastle, but most delivery comes from Central and Eastern Europe, India and Latin America. Its size suits large regulated programmes better than small or mid-sized builds.
