What if the biggest problem in digital advertising isn’t creativity or budget—but waste? In this episode of Leader Generation, Tessa Burg talks with Zach Rosen of Multilocal to unpack the growing shift happening in programmatic media and why brands are rethinking how they buy and optimize advertising.
Zach explains how AI-powered curation and sell-side decisioning are helping marketers reduce waste, improve performance and reach audiences in more meaningful moments. The conversation goes into why “cheap CPMs” are no longer the goal, how brands can focus more on outcomes instead of impressions and why better targeting doesn’t have to come at the expense of inclusivity or sustainability.
If you’re trying to make sense of AI’s impact on media, personalization and advertising performance, this episode offers practical insights without the hype. You’ll walk away with a better understanding of how smarter media buying can improve ROI, uncover overlooked audiences and help brands adapt to the rapid pace of change happening across marketing today.
