Former Nielsen exec joins MediaMath

Nicholas joins the company from Nielsen, where she spent 28 years, most recently as global client leader of the company’s FMCG global markets group. She also launched new vertical practice areas of Nielsen Europe, including automotive and financial services, and served as global client business partner for Unilever. 

At MediaMath, Nicholas will lead all client-facing teams and work alongside clients, reporting to president Konrad Gerszke.

Gerszke said: "Eleni’s experience in developing and leading large global client relationships, her passion for building world-class teams, and her client-centric continuous improvement mindset make her ideally suited to lead MediaMath’s client-facing teams through this next chapter of our operational transformation."

MediaMath has also appointed Guillermo Abud as senior vice-president of business development for Latin America and US multicultural, while Allie Kline, previously chief marketing officer at Verizon Communications’ subsidiary Oath (now Verizon Media) has joined the company’s board of directors. 

The new hires will all focus on initatives including expanding the company’s Source supply chain ecosystem and connected TV offer.
