Amazon's in-house cloud consulting arm, ProServe, is undergoing radical changes driven by the adoption of AI technology. This shift within ProServe, which influences over $10 billion in annual revenue for AWS, provides a glimpse into how the broader consulting industry may evolve in the AI era. As firms like PwC, EY, and KPMG grapple with how to deliver value and charge for their services in this new landscape, the impact of AI on hiring and workflows remains uneven across the industry.

This shift is impacting how firms like the Big Four (PwC, EY, KPMG, Deloitte) approach hiring, service delivery, and pricing models. Understanding these industry-wide changes is crucial as the next generation, like the author's daughter, prepares to enter the consulting field.

The details

ProServe, Amazon's in-house cloud consulting arm, is undergoing a radical transformation driven by the adoption of AI technology. The unit, which influences over $10 billion in annual revenue for AWS, is serving as a bellwether for the broader consulting industry as it grapples with how to deliver value and charge for services in the AI era. While the Big Four consulting firms (PwC, EY, KPMG, Deloitte) have a more diversified business model spanning audit, tax, risk, and strategy, they are also embracing AI and adapting their approaches unevenly. Hiring trends across the industry vary, with some firms like McKinsey, Accenture, and PwC reducing hiring, while EY is generally increasing entry-level hiring and KPMG is not making significant changes.
