Deloitte is implementing Anthropic's Claude artificial intelligence assistant across its entire global workforce, which includes over 470,000 employees. This initiative represents Anthropic's largest enterprise deployment to date, expanding upon an existing partnership between the consulting firm and the AI startup. To facilitate this massive integration, Deloitte will create specialized Claude "personas" tailored to different roles, such as accounting and software development, and will support staff through a dedicated Claude Center of Excellence.
