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..
