About the company

Deloitte audits companies and advises businesses and governments on tax, technology, and risk, and it is one of the Big Four, the world's four largest accounting firms. In 1849 its founder became the first independent auditor of a public company, Britain's Great Western Railway. Its auditors check companies' financial reports for errors and fraud before investors rely on them, while its consultants design strategy, install business software, and defend clients against cyberattacks. Clients pay fees for each audit or project, and each country's Deloitte firm is a separate business owned by its local partners. Deloitte was founded in London in 1845 and is based in New York.

What believers are saying

  • Growth keeps hiring going: revenue rose 5.7% to $74.5 billion and staff neared 500,000 in the year to May 2026.
  • AI is part of the job: in October 2025, Deloitte opened the Claude assistant to 470,000 people, Anthropic's largest rollout.
  • Making partner pays off: Deloitte UK's 784 equity partners averaged £1.125 million in profit in the year to May 2026.

What critics are saying

  • Tech consulting is lagging: it grew 2.5% in the year to May 2026, the slowest of Deloitte's four businesses.
  • Back-office benefits are shrinking: Deloitte US will halve parental leave to 8 weeks for internal staff in January 2027.
  • Federal work brings scrutiny: Deloitte agreed to pay $21.5 million in August 2026 over claims diversity targets swayed promotions.

AI forces companies to rethink hiring practices as job applications surge and entry-level pipelines shrink

Business Insider convened 15 HR and C-suite leaders in Davos to discuss how AI is reshaping hiring and talent pipelines. The roundtable, presented by Indeed, revealed growing concerns about entry-level positions and skills assessment. Deloitte's Elizabeth Faber emphasised maintaining a "human-led, technology-powered" approach whilst carefully navigating reduced junior hiring. TCW's Melissa Stolfi noted her firm has downsized its analyst class but maintains a pyramid structure to preserve apprenticeship culture and future leadership pipelines. Indeed's chief economist Svenja Gudell warned that whilst tech employers now demand five-plus years' experience, this creates future talent shortages if junior hiring continues declining. Salesforce's Nathalie Scardino said her company receives two million applications annually and has shifted focus from years of experience to learning aptitude. Manpower Group's Becky Frankiewicz noted AI can process candidates faster whilst reducing bias, potentially unlocking opportunities beyond traditional qualifications.
