Thoughtworks was founded in Chicago in 1993 and states that it has more than 10,000 employees working from 45 offices in 22 countries. The firm became widely known in software circles for its early advocacy of agile methods, continuous delivery and its periodic Technology Radar publication. After a period as a Nasdaq-listed company, it was taken private again by funds advised by Apax Partners in a deal announced in August 2024 that valued it at about US$1.75 billion, or US$4.40 per share; Apax was buying the shares it did not already own. As a private company Thoughtworks no longer publishes quarterly financial statements, so no current revenue figure is given here.

Its continued operation through the war in Ukraine, with most staff still based in the country, is the defining feature of its delivery model and a point that clients typically address in business-continuity reviews. SoftServe works across software product development, cloud, data and AI engineering, and has long-standing partnerships with the major cloud providers.
