Butterfield has nearly 30 years' experience in building brands and has advised a range of UK and international clients including British Airways, BT, Mercedes-Benz, Waitrose, Orange, Chrysler, Seagram and the UK Government.
Jez Frampton, group chief executive, said: "We are experiencing a growing need for our clients to assess how brand drives demand and an increasing desire to really understand brand ROI.
"It doesn't matter if it's a new identity, retail environments and packaging, or an analytics-driven demand model -- understanding value creation is ever more vital to business leaders."
Butterfield began his career in advertising at Boase Massimi Pollitt (now DDB London). He went on to become head of planning at Abbott Mead Vickers and later founded Partners BDDH.
In 2001, Butterfield created Butterfield8, a consultancy that later became one of the cornerstones of the Ingram Partnership -- the company started by Chris Ingram and his partners in 2003.
Ingram's decision to close the business in late 2007 lead to the creation of ButterfieldPartners.
Butterfield said: "I've always seen Interbrand as the world's leading brand consultancy and clearly the first name that comes to mind when you think of the sector, no matter where you are in the world.
"When offered this role, I jumped at the chance. It's a really exciting opportunity to join such a professional team and help them build on Interbrand's leadership position, and excellent reputation with clients."
