MadTech refers to the convergence of marketing technology (MarTech) and advertising technology (AdTech). It aims to bridge the gaps between these fields by combining customer data from various sources and using it to inform targeted digital advertising campaigns. MadTech benefits marketers by providing better customer insights, streamlining media buying and targeting, and eliminating data silos between MarTech and AdTech platforms. It is emerging as an important trend as the lines between marketing and advertising continue to blur.
