The Zentropy move comes as McCann WorldGroup brings two other businesses into the MRM operation, which already numbers Avaya, Buick, General Motors, Coca-Cola and L'Oreal among its clients.
Duncan, who was responsible for launching Zentropy Partners in the UK, will oversee the integrated London offices of: MRM Partners; Zentropy Partners; offline content publishers, Just Communications; and database analytics company Millar Starr.
"The focus on customer-centricity is changing the way every business interacts with its existing and potential customers. Bringing together the specialist divisions that deliver MRM Partner's focused customer relationship programmes -- and placing interactivity at the heart of them -- represents an important step forward," he said.
MRM partners has 62 offices in 37 countries and more than 1,700 employees.
