Thoughtworks vs Winder.ai: 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.
Winder.ai
Winder.ai is the trading name of Winder Research and Development Ltd, incorporated in Harrogate, England, in November 2013. Its chief executive, Phil Winder, wrote O'Reilly's book on reinforcement learning and was an early voice on MLOps. Company filings show a micro-sized firm, so expect a handful of senior people rather than a team. It lists Google, Microsoft, and Shell among past clients (per company website; independently unverifiable).
