Thoughtworks vs Capgemini: overview

Thoughtworks

Thoughtworks was founded in Chicago in 1993 and has roughly 10,000 staff. Apax Partners took it private in a deal announced in August 2024 and valued at about $1.75 billion. The firm popularized continuous delivery for machine learning (CD4ML), and its production AI work applies the same habits of automated testing, versioning, and small releases to models and prompts. Its twice-yearly Technology Radar lets you see its tool opinions before you hire it.

Capgemini

Capgemini was founded in Grenoble in 1967, is headquartered in Paris, and employs more than 340,000 people. In October 2025 it completed its acquisition of WNS, adding business process services that it plans to run with AI agents. Production AI here is usually part of a large program that includes process redesign and outsourced operations. It's a strong fit for European multinationals and a poor one for a single pilot.
