Marko Matejcic: Media Buyers and Alternative Data

In this episode of Selling Signals, we’re joined by Marko Matejcic, who has spent more than a decade building and commercialising data products across the advertising and marketing ecosystem. Marko has worked across identity, privacy, measurement, modelling and activation, giving him a practical view of how alternative data is actually used in media.We discuss how media buyers evaluate alternative data, how planning, activation, and measurement differ from investment workflows, and why attribution is such a difficult problem to solve. Marko explains where alternative data vendors often struggle when moving from hedge funds into media and what needs to change for data to be adopted and licensed by agencies and brands.This episode is essential listening for anyone selling or building alternative data who wants to understand how a very different data buying world operates.
