Thoughtworks vs Hippo Digital: 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.

Hippo Digital

Hippo Digital launched in Leeds in 2016, founded by Adam Lewis with co-founders including Robert Coop. Its early years were shaped by the DWP and Government Digital Service academies, and several academy graduates joined the firm. It employs around 400 people, with work centred on user research, service design and agile delivery for government and health.
