Scott Logic vs Thoughtworks: overview
Scott Logic
Former Lehman Brothers executive Gary Scott founded Scott Logic in Newcastle in 2005. It now employs 400+ people across Newcastle, London, Edinburgh, Bristol and Leeds, all in the UK. The firm is best known for trading and capital-markets software and for central government digital work. Every engineer is UK-based, which suits security-cleared and data-sensitive projects but rules out offshore cost savings.
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.
