The 11 Most Prestigious Consulting Firms in the World (2020)

What are the most prestigious consulting firms in the world? While prestige should not be the only factor in deciding which consulting firm to work for, working for a prestigious consulting firm can provide you with a strong network and attractive exit opportunities.

 

There are many different types of consulting, including management consulting, technology consulting, and economic consulting to name a few. This article focuses on identifying the top 11 most prestigious management consulting firms.

 

To do this, we analyzed over 75 different consulting firms that were ranked by Vault and Consulting.com.

 

We excluded consulting firms that are not management consulting firms, do not have a global presence, and do not serve a wide range of industries and functions.

 

Of the remaining management consulting firms, we grouped them into three different tiers:

  • Tier One: MBB (McKinsey, BCG, Bain)

 

  • Tier Two: Well Known Management Consulting Firms

 

  • The Rest: Lesser Known Management Consulting Firms


Tier 1: MBB (McKinsey, BCG, Bain)

 

The top-tier consulting firms are collectively known as MBB, which stands for McKinsey, BCG, and Bain. These three companies are the most prestigious management consulting firms to work for.

 

MBB hires the smartest people, pays the highest compensation, and has the best exit opportunities. These firms have the biggest name clients and charge the highest billing rates.

 

McKinsey & Company: The oldest and largest firm out of MBB has over 30,000 employees, 130+ offices around the world, and $10.5B in annual revenue. McKinsey is known as the “gold standard” in management consulting and is the most recognized management consulting firm in the world. McKinsey hires the smartest and most talented people and has generated the greatest number of Fortune 500 CEOs. McKinsey has knowledge and expertise in all industries, but is the clear leader in healthcare, government, education, and public sector work.

 

Boston Consulting Group (BCG): The second oldest and largest firm out of MBB has 21,000 employees, 90+ offices around the world, and $8.5B in annual revenue. BCG has knowledge and expertise in all industries. They are known for being academic thought leaders.

 

Bain & Company: The smallest, but newest firm in MBB, Bain has 8,000 employees, 59 offices around the world, and $4.5B in annual revenue. Bain has knowledge and expertise in all industries, but is the clear leader in private equity work. Bain is known for its amazing culture with an emphasis on being fun and collegial.

 

Tier 2: Well Known Management Consulting Firms

 

The next tier of consulting firms are all well-known, but do not have the same prestige as MBB. Nevertheless, they are still management consulting firms that serve clients in a variety of industries and functions.

 

Deloitte Strategy & Operations: Although part of the Big Four Accounting Firms, Deloitte does have consulting services, which is comprised of Strategy & Operations, Technology, and Human Capital. Collectively, these generate $11.5B in annual revenues. Their management consulting division is known as the Strategy and Operations practice area.

They have experience working in many different industries, but are best known for their expertise in the financial services sector.
