Deloitte on Monday revealed plans to integrate Anthropic’s AI assistant, Claude, across its global workforce of over 470,000 employees.

This initiative marks Anthropic’s largest enterprise deployment to date, expanding on a partnership the firms announced last year.

Deloitte, a provider of consulting, tax, and audit services, is among the 300,000 business clients Anthropic has gained since its founding four years ago.

“We are both investing a significant amount in this partnership, whether that’s financial or whether it is just simply the engineering resource that we’re going to put into this as well,” Paul Smith, Anthropic’s chief commercial officer, told CNBC.

The companies did not reveal the financial terms of the agreement.

Over the coming months, Deloitte plans to develop and roll out different Claude “personas” tailored to various employee groups, including accountants and software developers.
