BUSINESS MODEL
Consulting 4.0: The Core Thesis
THE CHALLENGE
Traditional consulting has a structural limitation: linear relationship between revenue and headcount.
THE SOLUTION
Embed AI and automation into consulting delivery to "augment" the consultant rather than replace them.
"Not since the company was founded has such a fundamental strategic direction been made."
— Matthieu Courtecuisse, CEO
