M&C Saatchi was founded in 1995 by brothers Maurice and Charles Saatchi alongside several key colleagues after a dramatic boardroom coup forced their departure from their original namesake agency, Saatchi & Saatchi. Starting as an independent challenger agency in London with high-profile accounts like British Airways, the firm expanded rapidly across global markets through organic growth and strategic acquisitions. Over the decades, it evolved into a vast international network specializing in advertising, public relations, design, and digital transformation, listed publicly on London's AIM market while continuously adapting its operating model to modern marketing landscapes.
