According to MRM, the reorganisation includes integrating partner firms, database specialist Miller Starr and digital shop Zentropy Partners, into the brand.
As part of this Bradley Starr, of Miller Starr, takes the role of executive vice-president of database and analytics.
Reuben Hendell, MRM Worldwide chief executive officer, said: "We are very excited and proud to announce MRM Worldwide, a company born out of an innate understanding of how customer relationship management has changed in the 21st century."
MRM Worldwide, which has 2,000 employees in 34 countries and is part of the Interpublic Group-owned McCann WorldGroup, has a client list that includes Microsoft, General Motors, Nestle, Johnson & Johnson and Dell.
Earlier this month, MRM announced a series of new hires, including Maria Dillon from Good Technology to work on the Unilever account and Robert Mahadeo joining the Microsoft and Nestle teams, having previously worked at Abbey National.
MRM Partners was recently dropped from the COI direct marketing roster, along with FCBi and Lida.
