Goldschmidt, Knox and Piacenza resigned from their posts at the end of March. 

Ebeling (pictured) is CEO of ProSiebenSat while Huth and Freise both hold positions at private equity firm KKR (head of EMEA operations and head of technology, media and telecommunications, Europe, respectively). KKR acquired an 18.54% stake in GfK in February.

“The outgoing supervisory board members welcome the partial new composition of the supervisory board sought by KKR and GfK Verein," said Ralf Klein-Bölting, chairman of the supervisory board of GfK SE. 

"Accordingly, they have offered to vacate their respective seats in an extraordinarily unselfish manner from the onset. Therefore, also on behalf of the other supervisory board members, I sincerely thank them for their outstanding efforts, great engagement and competent support of GfK.

"Peter Goldschmidt, Aliza Knox and Bruno Piacenza have done an excellent job for GfK, actively supporting the company’s digital transformation with their passion and diverse experience from different industries. We are delighted to have worked with them over the past years and are very grateful for their valuable contributions to the development of GfK.” 

GfK named Peter Feld as CEO last month after previous CEO Matthias Hartmann left the company last year.
