Metzke, who takes over from Gunnar Piening who has left the company, will oversee the separation of Ciao!'s two business units, online surveys and comparison shopping, into individual business units over the coming months.
Metzke said: "Separating the two businesses represents a new chapter in Ciao!'s lifecycle. I believe we have many opportunities in front of us and Ciao! has a strong team in place to help me execute on our sales growth and client service objectives."
This month Ciao!, part of Greenfield Online, has expanded in the Asia Pacific market with the opening of an Australian office in Sydney.
Earlier this year, the firm added 40 new jobs throughout Europe as part of a major reorganisation of its client services department in March.
