Greenspoon (pictured) will replace Wayne Levings, chief client officer at Kantar, who also additionally led the Americas business for the data and analytics company for the past two years. Levings will return to the UK to focus on his chief client officer responsibilities.

Greenspoon joins Kantar from Dentsu, where he most recently served as chief global client officer and chief business officer for the Americas.

Other former Dentsu roles include becoming the business’ first chief product officer, followed by CEO of Canada and global president of integrated solutions.

Greenspoon was also co-founder and chief executive at Spoke, a digital creative firm acquired by Dentsu in 2014.

At Kantar, Greenspoon will sit on the group executive team, reporting to chief executive Chris Jansen.

Jansen said: “Jeff brings a wealth of experience in entrepreneurship, marketing and strategy. His deep understanding of the marketing ecosystem, global client c-suite experience and proven track record of building high-performing teams make him a great fit for Kantar and our Americas business.

“His fresh perspectives and passion for growth make him a powerful addition to our executive team. I’m confident our teams and clients will be struck – as I was – by his energy, creativity and commitment to client impact.”
