Deloitte, founded in London in 1845, has about 470,000 people and provides audit, tax and consulting services1.
Best for: Large companies that want AI built on a modernised data foundation, from a firm that also audits and advises.
Not the right fit for: Mid-sized companies that want quantified, named results before they engage, and accounting firms, for whom it is a competitor.
What Deloitte's AI practice does
The AI & Data practice designs, builds and runs AI solutions, including generative and agentic AI, alongside data engineering, analytics and DataOps. On 31 August 2026 it announced the acquisition of Wavicle, a data and AI engineering firm2.
The case studies on its AI & Data page include a B2B commerce platform for an unnamed equipment manufacturer and data work for banks and a university. None gives a quantified result, and none is in the six industries this site covers2. Accounting firms should note that Deloitte is itself one of the largest audit and tax firms.
