What Does MBB Mean?

MBB is an acronym that represents the three leading consulting firms globally: McKinsey, BCG, and Bain. These firms are renowned for their expertise in strategy consulting and are consistently ranked as the top destinations for aspiring consultants.

The Origins of MBB

The term "MBB" has become synonymous with excellence in the consulting world, but its origins are rooted in the unique history of each firm. McKinsey & Company was founded in 1926 by James O. McKinsey as a firm that combined accounting principles with management theory to solve complex business problems. BCG was established in 1963 by Bruce Henderson, introducing new strategic frameworks that reshaped industries. Bain & Company was founded in 1973 by Bill Bain, revolutionizing client engagement by ensuring that the firm's compensation was tied to the success of its clients.

Why MBB Firms Are Considered the Best

MBB firms are distinguished by several key factors that set them apart from other consulting firms:

• Prestige and Reputation: MBB firms consistently rank at the top of industry surveys and are known for their prestigious client list, which includes Fortune 500 companies, governments, and large global organizations.
