Everything we do is driven by data and embraces technology. We employ close to 4,000 people across 42 offices in 15 countries, incorporating 22 subsidiary agencies spanning digital content, marketing, PR, consumer, technology, marketing software, market research, public affairs and policy communications.

Our Mission

We view our clients through this digital lens to knit together insight, creative, business design, digital build and customer engagement under one roof to solve today’s most pressing business challenges.
