Thoughtworks vs EPAM Systems: 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.
EPAM Systems
EPAM Systems was founded in 1993, is headquartered in Newtown, Pennsylvania, and employs more than 61,000 people. It bought NEORIS and First Derivative in recent years to expand in Latin America and financial services. Its AI work sits inside a large software engineering business, so production AI usually arrives as part of a broader platform or product program. That suits enterprises with many products more than a company with one stalled pilot.
