Adrian Coleman, co-founder and group chief executive at VCCP, said: "Growth for us isn’t about having dots on a map all over the world, it’s about having a small number of offices strategically positioned in global client hubs.
"What’s most important to us is the culture and creativity within each of our offices being unified. We believe creativity is still the biggest multiplier for any business, and we want to offer that creativity to ambitious brands all over the world."
