Summary

Within the first hour, we were able to identify a list of the top 50 consulting firms globally by revenue, and to conclude that the number of branches broken down by country is available for most, if not all, companies on that list.

We have also identified other top lists of management consulting firms, like the top list from Consultancy.org, but these lists were either based on more subjective criteria, or were significantly shorter (the top 5 or the top 10, for example).

Please note that building on the top 50 list to arrive at a list of the top 100 management consulting firms globally would require manual research to determine the revenues of other consulting companies and to rank them accordingly.

For a deeper dive into the number of branches each of the top 50 consulting firms has in each country, we recommend further research. Details on our recommended research paths have been provided in our proposals below.
