In 1990, she joined Nielsen in Cyprus for a role as a customized research executive. She would then rise through the ranks, with positions in Dubai, Moscow, Amsterdam and, ultimately, the English city of Oxford.
There, this veteran executive eventually rose to become the Global Client Business Partner for Unilever and, from June 2018, the FMCG Global Markets Group Client Leader.
Now, Eleni Nicholas has exited the only employer she’s ever known since graduating from the London School of Economics. She’s been appointed Chief Client Officer at a New York-based ad tech company for brands and agencies that is also welcoming a new SVP of Business Development for the U.S. multicultural market and Latin America.
Nicholas, who exited Nielsen in May, is now at MediaMath, which has brought on Guillermo Abud for the CALA region and U.S. multicultural efforts it will be carrying out.
“These additions will help propel MediaMath forward on its mission to rearchitect the digital advertising ecosystem with a fully accountable, addressable and aligned supply chain,” the company said on Wednesday.
Nicholas and Abud will focus on key initiatives, such as expanding the MediaMath SOURCE supply chain ecosystem “with new, industry-leading solutions at scale to unleash ever-growing advertising opportunities, and bolstering CTV solutions to deliver better accountability and addressability to brands and agencies through proven accuracy, scalability and fast time-to-insights.”
Nicholas will be responsible for leading all client-facing teams globally, assisting MediaMath’s clients in helping them improve the return on their digital marketing investment. She reports to MediaMath President Konrad Gerszke, who 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 that makes the vision reality more and more every day. I look forward to the many ways her leadership will improve relationships and results for our clients and partners.”
Nicholas added, “I built a belief in measurement as the solution at Nielsen and saw that the connection of business goals and metrics to media buying and execution directly was the future. That measurement will quickly become real-time decisioning for marketers with a globally addressable and accountable connection to consumers via high-quality media across all screens and speakers globally. I wanted to be in a mid-sized global company that had big ambitions and enough smart, talented, and good people to make them come true.”
He will be reporting to the GM of the Latin America region, Justin Kuykendall.
“His global expertise and extensive experience in leading teams focused on programmatic media buying across Latin America and the U.S., coupled with his agency background, makes him a strong addition to our leadership team,” Kuykendall said.
