Mercer is advising clients on workforce well-being and retirement, and Stax is guiding investors through the high-stakes work of due diligence and value creation. In the industries they serve, these firms are delivering results that shape how modern businesses evolve.
Consulting has become one of the most consequential forces shaping modern institutions. The influence of these awardees is felt in boardrooms, on factory floors, in government agencies, and across digital ecosystems. Selected through a methodical process that considered each firm’s track record, leadership, and client impact, these consultancies represent the highest standards in the field.
