Different kinds of consultants

Consulting is much like other industries, with a few big companies and a long tail of competitors.

The Big 4

The Big Four are the world’s largest consulting firms, accounting for nearly 40% of the industry's $150 billion global market. PwC, Deloitte, EY and KPMG are followed by US strategy giants McKinsey & Company and The Boston Consulting Group..

When it comes to strategy, McK, BCG, Bain dominate the market.

The mid-tier

Below the big guys are many smaller mid-size consultancies who specialize in one industry or vertical. During our interviews 20200617 consulting interviews notes we heard about:

The small fry

There are endless independent consultants and smaller consulting firms. They are generally geographically or vertically (sales, marketing) focused. Some examples
- “The world expert on subscription pricing and membership models” -
- Keynote speaker and best-selling author Nir Eyal writes, consults, and teaches about the intersection of psychology, technology, and business -
- BtoB specialist, WHY Consulting supports you from the definition of your development strategy to its execution
