Big four consultancy Deloitte has committed to deploying Anthropic's Claude across its entire global workforce of more than 470,000 employees spanning 150 countries.
It's the AI startup's largest enterprise deployment since its founding four years ago, and the expanded partnership builds on an alliance first struck in July 2024.
Neither company disclosed financial terms, though Anthropic's chief commercial officer, Paul Smith, told CNBC both firms are investing heavily in the partnership through direct capital and engineering resources dedicated to the rollout.
Deloitte will establish a Claude Center of Excellence staffed with specialists developing implementation frameworks and providing technical support to move AI pilots into production at scale.
It will also co-create a certification program to train 15,000 professionals on Claude for internal and client deployments.
The firm plans to deploy different Claude "personas" tailored to specific roles over the coming months, from accountants analysing financial structures to developers writing production code.
Ranjit Bawa, Deloitte's global technology and ecosystems leader, said the internal deployment serves dual purposes - boosting productivity whilst positioning Deloitte to advise clients more credibly on AI transformations.
The collaboration extends into building AI solutions for regulated industries, including financial services, healthcare, and public sector organisations, combining Claude's safety-first design with Deloitte's Trustworthy AI framework, where compliance requirements run deep.
For Anthropic, the Deloitte deployment validates its enterprise positioning against OpenAI and Google as the AI race matures beyond prototype experiments into production systems handling sensitive data.
The Amazon-backed AI tech now counts more than 300,000 business customers, with nearly 80% of usage coming from outside the U.S.
Anthropic hit a US$5 billion revenue run-rate recently, up from $87 million at the start of 2024, following its $13 billion funding round at a $183 billion valuation.
The company said in September it would triple its international workforce this year, recruiting country leads across India, Australia, Korea, and Singapore, whilst expanding across Europe.
