Inside the Stack

ChatGPT has officially entered the advertising business. But launching ads is the easy part.  In this episode of Inside the Stack, Mary Gabrielyan, Chief Strategy Officer at AI Digital, explains why measurement, attribution and transparency remain the biggest challenge for determining whether ChatGPT becomes a meaningful media channel. She also shares why ChatGPT ads are likely to be contextual, intent-based, and performance-driven. The episode also dives into what the rise of another walled garden means for marketers, the Open Garden approach, why Google may still have the edge and why AI still needs human judgment.

Tatari CRO Andy Schonfeld argues that programmatic isn't a TV strategy. It's simply one tool in a much bigger stack. He talks about why DSP-only buying misses a huge chunk of the TV marketplace, including live sports and linear. Schonfeld also explains Tatari's Upstream technology for automating direct IO buying with major networks and shares how AI is used within the platform — from media planning to creative compliance. Plus, we talk about why he thinks the future of TV comes down to three words: direct, automation, and convergence.

On this episode of Inside the Stack, Cynopsis' Lynn Leahey sits down with Benjamin Heaton, Senior Director of Product Management at Tatari, to talk about why TV ad measurement is breaking down, and what it will take to fix it. They dig into signal loss, why traditional identifiers no longer work, and why most clean rooms weren't built for TV workflows in the first place. Heaton explains how Tatari's Vault was designed to support privacy-first infrastructure that works across publishers and advertisers. No double-counting or black boxes. If you're trying to measure TV performance in an ad tech world with fewer signals and higher expectations, this conversation is for you.  

On this episode of Inside the Stack, we sit down with Brian Gleason, CEO of Seedtag, to talk about the future of contextual advertising. We dig into neuro-contextual advertising, how Seedtag's AI understands tone, emotion, and environment across web and CTV, and why the industry needs to move from relevance to resonance. We also unpack what this shift means for brands chasing impact, agencies planning in a privacy-first world, and publishers seeking to have their quality content rewarded again. The future of contextual is less about targeting people and more about what content surrounds an ad and how it makes people feel.

Most marketers obsess over online conversions — but 85–90% of transactions still happen in physical retail. So why isn't in-store media getting the same attention? On this episode of Inside the Stack, Grocery TV CEO Marlow Nickell tells us why in-store retail media is "inevitable" and what brands miss when they overlook the influence happening at the shelf. We get into: • Why in-store screens are becoming a core part of retail media • How context and placement shape shopper behavior • What brands can realistically expect when it comes to measurement • Why attribution doesn't need to mirror digital to prove value • The shift toward true omnichannel planning As Nickell asks: "Do you really need that level of granularity — or do you just want to understand how your campaign performed?" Here's a fresh look at the channel hiding in plain sight.
