BCG's biggest AI jobs now get paid on results, not hours.
The largest strategy house says most of its marquee AI engagements carry fees that rise and fall with the client's outcome, and the billable hour is losing its grip.
In a Wall Street Journal interview published May 28, 2026, BCG chief executive Christoph Schweizer said companies now have a near infinite need for help rolling out AI, and the firm is racing to meet it. Then came the pricing detail that matters. On BCG's largest AI engagements, roughly three quarters now carry a variable fee, meaning the payment moves with what the client actually achieves rather than the hours the team books. Schweizer told investors the firm expects AI work to make up around 40 percent of revenue by 2026, up from roughly 20 percent in 2024.
Consider what that reverses. The billable hour built the consulting industry. A firm sold time and expertise, and the meter ran whether or not the client got a result. A variable fee inverts the incentive: the house earns more when the client wins and less when it does not. For the sector that invented time and materials, agreeing to be paid against the outcome on its highest profile work is a structural concession, not a marketing line.
One caveat keeps this honest. A variable fee is not the same as guaranteeing a loss, and across BCG's broader book, outcome linked pricing still sits well under a third of the work. So this is a shift at the top of the engagement list, the flagship cases, not a firm wide rule. But the direction is unmistakable, and it is being named in the national press by the largest strategy house rather than whispered in a pitch.
Why now. Schweizer framed the value gap as BCG's own market: most chief executives struggle to get value from their AI spend, and that struggle is the opportunity. Pricing against the result is a way to sell into that skepticism. It is also a bet that the firm can measure the result precisely enough to invoice against it. That measurement, the audit trail behind the number, is the part still waiting to be shown.
