N-iX vs Thoughtworks: overview
N-iX
N-iX started in Lviv in 2002 as Novellix, building applications for Novell's Linux platform, and Novell became its first large client. It now reports more than 2,400 engineers in Ukraine, Poland and other countries. In the UK it trades through N-iX Technologies Limited, registered in London in 2022, though public sources do not show a staffed UK delivery office. It suits buyers who want a large Central and Eastern European engineering pool and are comfortable managing it remotely.
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.
