Codurance vs Thoughtworks: overview

Codurance

Mashooq Badar co-founded Codurance in London in 2013. Its pitch is software craftsmanship: test-driven development, pairing and clean architecture. Besides London and Manchester, it has offices in Barcelona, Madrid and Lisbon, which bring Iberian rates into the mix. Headcount estimates range from roughly 170 to 300.

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.
