Top 10 Business Consultant Companies in 2023 (Updated)

business consultant companies

The demand for business consultants is on the rise; leading to the establishment of business consultant companies across the globe.

This high demand stems from the strong desire for growth by business owners and CEOs.

As a matter of fact, statistics show that, in the United States alone, business consultants receive over $2 billion for their services.

Though that amount is not a pretty large sum given the kind of services they render. These services range from effective diagnosis and in-depth analysis to permanently improving the business’ effectiveness.

But a problem arises with questions like:

“Which business consultant company should I hire?”

“How do I know this business consultant company is reliable?”

Take a deep breath, because you are about to get answers to these indecisive questions.

This post covers the top 10 business consultant companies to hire if you are ever confused.

Also, I ranked these companies with the following criteria:

  • Revenue
  • Prestige
  • Employee Satisfaction
  • Compensation
  • Benefits

However, let’s start with the basics…

What Makes Top Business Consultant Companies Rank as One?

Yes, MBB firms have the most prestige, but there may be other firms that are more suited to your unique career path. Do you have a plan for what you want to do a following consultation? Are you going to choose the consulting organization with the most clients? If that’s the case, you might be startled to learn that neither McKinsey, BCG, nor Bain are among the top ten revenue-generating consulting firms.

Some consulting organizations require nearly all of their employees to travel, while others require far less. Some charge by the hour, while others charge by the project—there’s a major cultural difference between being rewarded for completing work swiftly and racking up billable hours. You might wish to join a specific diversity organization or live in a specific city. All of these factors should be taken into account as you narrow down your personal list of target companies.
