The professional services pyramid has always rested on a particular trade. A wide base of junior auditors and consultants would work eighty-hour weeks during busy season at modest hourly rates. A thin layer of partners at the top would extract the difference between what those juniors cost and what their hours billed. Everyone signed up for the deal on the understanding that the long climb up the pyramid was worth it because the view from the top — partnership, equity, seven-figure pay — was worth the years of cheap labour underneath. The shape of the structure was justified by the size of the reward at its apex.
Reporting this month in the Cayman Compass suggests that structure is now being eaten from below. Artificial intelligence has begun to perform the basic audit work — data aggregation, sampling, document review, testing, presentation — that the bottom of the pyramid was built to absorb. Clients know it. They are paying for it accordingly. And the firms, whose entire economic model presumes a particular ratio of cheap juniors to expensive partners, are now navigating a transition whose endpoint nobody yet has the courage to describe out loud.
What the Pyramid Was For
Cayman is one of the more concentrated expressions of the pyramid model anywhere in professional services. Statute requires that Cayman-registered funds and operating companies be audited by firms physically based in the jurisdiction. That single legislative provision guarantees a recurring stream of audit revenue to the firms that maintain offices on the islands, and gives the Big Four — Deloitte, EY, KPMG, and PwC — a structurally protected client base. The competitive question for those firms is therefore not how to win the work, but how to deliver it at the lowest possible cost.
The cost-control strategy that emerged is the one familiar to anyone who has worked at a Big Four firm anywhere in the last two decades. Entry-level audit staff are recruited from progressively lower-income jurisdictions. A mid-level professional quoted by the Compass put entry-level audit pay in Cayman at roughly $55,000 a year for what can be eighty-hour weeks in busy season. The composition of the workforce has shifted accordingly. In the 1970s and 1980s, almost all auditors in private practice were Caymanian or British. Canadians dominated the 1990s and 2000s. South Africans arrived in the 2010s. By the early 2020s the intake had widened to include large numbers of Indians, Kenyans, Zimbabweans, Tanzanians, Filipinos, and Nepalese. The work itself, increasingly, is performed offshore in global delivery centres in low-cost jurisdictions and signed off by a Cayman-based partner. The local firm operates as the regulatory wrapper. The actual hours sit elsewhere.
The AI Squeeze
What is changing is that artificial intelligence has begun to do, in minutes, the work that the global delivery centres were built to do at scale. The signal that the industry has crossed a threshold came earlier this year when the Financial Times reported that KPMG had asked its own auditor, Grant Thornton UK, to reduce its monthly accounting fees — on the grounds that KPMG knew, from its own use of the technology, that AI made the work cheaper to perform. Clients have absorbed the implication. If the Big Four are using AI internally to compress the cost of producing audit reports, the rates being charged for those reports should fall accordingly.
The headline numbers are now visible in the firms’ own employment data. KPMG announced approximately 600 UK job cuts earlier this year. PwC made 175 junior auditors redundant in the UK in 2025. The Financial Times reported that across 2025 the Big Four collectively advertised more AI specialist roles than auditor positions — a structural inversion of the pyramid that is hard to read as anything other than a deliberate substitution. Starting salaries for Big Four consultants, the FT also reports, have not risen since 2022.
The economic model that is breaking is, more precisely than “AI replaces auditors,” the model of time-and-materials billing. The Big Four sold hours. Hours were the unit because hours were the input. When the input collapses to a fraction of its former cost, the price the market will bear for the output collapses with it. A former partner quoted in the Compass piece described the shift directly: the historic billing model is giving way to value-based pricing on the relatively narrow band of work where critical thinking is genuinely required, with everything below that band priced toward zero.
Where the Pressure Lands
Inside the firms, the politics of where to absorb the squeeze are unambiguous. Partners control the decision. The former partner quoted in the reporting put the calculation in the plainest possible terms: if cuts have to be made, partners want them made below the partnership line. In a pyramid model, that means the base. Junior and mid-level staff perform exactly the tasks AI is now best at — the market research, the document review, the modelling, the testing, the sampling, the presentation work — and they are therefore exactly the staff whose roles compress first.
For Cayman specifically, this raises a question the jurisdiction has not yet had to confront in this form. The audit firms will continue to exist because statute requires them to. The partners will continue to be well compensated because the regulatory wrapper retains its value. What is uncertain is how many junior auditors the islands will need going forward, and where they will come from. Every professional interviewed for the Compass piece expected fewer junior hires in Cayman in the coming years. The concentrated effect on the local labour market is straightforward: fewer entry-level slots, harder competition for Caymanians attempting to enter the profession, and a continuing reliance on cheap offshore inputs for the work that AI has not yet absorbed.
A wider question sits underneath. The Big Four employment pyramid has historically been one of the most reliable training grounds for the global accounting and finance professions. A generation of CFOs, controllers, and finance directors learned their craft inside it. If the base of the pyramid shrinks decisively — not as a cyclical adjustment but as a structural one — the question of where the next generation of senior finance professionals is trained becomes an open one. The firms themselves have a clear short-term interest in defending partner economics. The longer-term replenishment of the talent that eventually becomes those partners is somebody else’s problem.
None of this is, in the words of the mid-level source in the Compass piece, going to destroy the Big Four. It will, however, drastically change the business and revenue models on which they have operated for thirty years. The pyramid was a deal between a generation of juniors and a generation of partners. The deal is being renegotiated, and the juniors are not at the table.
