Convergence of Advertising Technology (AdTech) and Marketing Technology (MarTech) is inevitable due to the need for cohesive cross-channel experiences, transparency, and ROI. The industry shift is driven by factors such as massive drive towards customer experience, first-party data, audience attribution, subscription recurring revenue, and advances in AI/ML. Data plays a crucial role in connecting these two worlds, enabling relevant impressions at scale, tying aggregated pools to individuals, personalizing ad messaging and creative, and powering mass personalization. The virtuous exchange of value occurs by combining the strengths of AdTech's decision-making capabilities with MarTech's data analysis and attribution, offering customers transparency and agility. As a result, we are witnessing a broader array of engagement and touchpoints throughout a customer journey at a better economic outcome.
