Episode 158: Rajeev Goel Is Making Agentic Advertising a Reality

Rajeev Goel, CEO of PubMatic, joins Ari Paparo and Eric Franchi to discuss how agentic AI and AdCP are reshaping the media buying process, collapsing the ad tech value chain, and creating new opportunities for publishers and advertisers to compete with walled gardens. Takeaways Agentic AI can automate planning, buying, and optimization beyond today’s DSP workflows. PubMatic’s AgenticOS lets advertisers transact through AI agents using AdCP. AI efficiency may grow digital ad spend and shift more ROI budgets to the open internet. Seller agents and marketplaces could help publishers unlock demand without big sales teams. The open web will compete better with stronger identity, measurement, and a simpler supply chain.

Paul Knegten draws on his experience as a former Beeswax CMO and long-time ad tech marketer to explain what actually works in marketing as the industry heads into 2026. The conversation covers AI hype versus real value, why founder voice matters more than positioning decks, how buyers actually make decisions, and the difference between a marketing problem and a real business problem. Paul also breaks down where ad tech companies lose the plot when talking to brands and agencies, and why relevance beats buzz every time. Takeaways AI does not fix weak positioning and only works when it solves a real customer problem. Founder-led communication often outperforms polished brand messaging in ad tech. Buyers care more about results than transparency when performance is strong. LinkedIn and major industry events remain the two most effective channels to reach decision makers. Many companies think they have a marketing issue when they actually have a product-market fit problem.

Ari Paparo and Eric Franchi are joined by Erez Levin, a former Googler who focuses on media and inventory quality. They dig into what “quality” really means in programmatic advertising, why short-term outcomes can be misleading, and how incentive structures have pushed spend toward lower-value impressions. Takeaways Quality is best understood through effectiveness, but most measurement overweights short-term signals.  “Not all impressions are created equal.”  quality varies by context, format, and goal.  Video definition loopholes led to premium pricing for lower-attention formats and contributed to market confusion.  MFA, SPO, and curation are connected symptoms of incentives that reward cheap scale and vanity metrics.  Verification helps, but quality needs to be addressed across the full media workflow, including experimentation and MMM.  Agentic buying could either improve quality controls or make it easier to optimize only to what’s measurable in the near term.  Publisher traffic declines reinforce the difference between commoditized content and differentiated journalism or creator-led media.  Chapters 00:00 Welcome and introduction to media quality 01:29 Marketecture Live updates and announcements 04:18 Erez Levin on why advertising quality matters 06:00 Defining quality vs outcomes in digital advertising 08:30 Brand impact, long-term effectiveness, and mental availability 09:43 Lessons from Google AdX and DV360 10:58 Video misclassification, IAB definitions, and market fallout 14:03 Outstream video, pricing, and mobile gaming use cases 17:00 MFA, SPO, and the real causes of inventory quality problems 19:03 Tools, verification, and the role of measurement frameworks 20:30 Agentic buying, AI, and control over media quality 22:41 AI news: Google UCP, AdCP, and agentic commerce 30:13 Apple, Siri, and Google Gemini’s implications 34:16 Publisher traffic decline and the future of content 36:23 Agentic buying vs RTB and portfolio theory 42:34 AppleCart funding and influence-based advertising 45:04 Liftoff IPO filing and the mobile ad tech landscape 47:57 Google antitrust lawsuits update 49:03 Closing thoughts and wrap-up Learn more about your ad choices.

From CES, Ari Paparo talks with Co-founder and CEO Tim Vanderhook and Co-founder and COO Chris Vanderhook of Viant about what automation looks like in a DSP workflow, using Viant’s Lattice Brain and Outcomes as the framing. They cover how goal-based optimization is set up (CPA/ROAS), what they observed in tests comparing automated and human-managed campaigns, and why “decision latency” is a recurring issue in day-to-day programmatic execution.  Takeaways They describe Outcomes as a goal-based workflow where an advertiser provides key inputs and the system handles ongoing optimization decisions. The guests share results from internal tests comparing automated vs human-managed campaigns, and discuss what signals they looked at beyond the final CPA. A main theme is “decision latency”; humans operate on meeting and approval cycles, while automated systems can adjust continuously. They distinguish between transparency and control: visibility into where spending goes, but limited ability to override optimization choices. They expect a hybrid approach, with some budgets remaining hands-on and others shifting toward more automation.

Takeaways Layers automates marketing for developers who lack marketing skills. Vibe coding allows non-professionals to create viable apps. AI tools are improving the quality of code produced by non-developers. Organic growth is becoming increasingly important for app distribution. App Store Optimization is crucial for visibility in app stores. TikTok and Meta are key platforms for app marketing. Non-technical individuals can successfully build and market apps. The rise of niche apps is creating new opportunities in the market. Developers can focus on building features rather than marketing. The future of app development is empowering individuals to create without needing extensive technical backgrounds.

Walmart Connect has quickly evolved from a search-driven retail media platform into a full-funnel advertising powerhouse. In this episode, Ari Paparo sits down with Khurrum Malik, VP of Business and Product Marketing at Walmart Connect, to unpack how Walmart is combining on-site search, off-site media, CTV via Vizio, and closed-loop measurement to spark real sales impact. Khurrum shares why he joined Walmart Connect, how “couch to cart” is becoming a reality, what performance TV means for emerging advertisers, and why incrementality is the new gold standard for retail media. The conversation also previews Walmart Connect’s CES announcements, including AI-driven ad tools, search incrementality GA, and new third-party benchmarks that position Walmart Connect against digital and social media. Takeaways Walmart Connect is a multi-billion-dollar retail media business growing 30%+ by focusing on sales impact, not just media delivery Search and PLAs remain the core, but Walmart Connect is expanding aggressively into brand, video, CTV, and off-site media Vizio enables true “couch to cart” activation by connecting CTV exposure directly to Walmart sales outcomes Incrementality and IROAS are becoming the measurement bar for retail media, not just attribution Walmart’s omni-channel footprint of 4,600+ stores and 150M weekly shoppers is a core competitive advantage CES announcements highlight AI-powered tools, search incrementality GA, and third-party benchmarks that outperform digital and social media norms Chapters 00:00 Welcome & Introduction 00:38 Why Khurrum Joined Walmart Connect 02:18 What Is Walmart Connect Today 03:57 Beyond PLAs and Search 05:03 Scale, Brand, and Performance 06:33 Measurement and Incrementality 06:47 Vizio and “Couch to Cart” 09:30 Performance TV for Emerging Advertisers 11:09 Third-Party Measurement & Trust 13:50 CES Preview 17:10 Lightning Round 19:31 Wrap-Up Learn more about your ad choices.

On Marketecture Live, Jayson Dubin, CEO and Founder of Playwire, explains how publishers can grow revenue and improve performance by combining machine learning with human intelligence. He shares concrete results from AI-driven traffic shaping and price floor optimization, walks through Playwire’s Quality, Performance, Transparency (QPT) initiative, and discusses major ecosystem issues like supply chain opacity, malicious ads, and the shifting realities of AI-driven discovery. He also introduces RAMP, Playwire’s Revenue Amplification Management Platform, built to give enterprise publishers control, visibility, and optional AI automation. Takeaways AI is best for repetitive, rapid decisions; humans are best for contextual strategy and judgment in a gray, complex ad ecosystem. AI traffic shaping drove a 21% lift in Revenue Per Session versus 9% without it. AI price flooring delivered about a 20% uplift in RPM through multidimensional, per-request adjustments. Cutting bid requests can increase performance and revenue while also improving page speed and traffic. QPT shifted Playwire from quantity to quality, strengthening trust with buyers and partners. Transparency remains uneven: publishers still struggle to identify buyers and stop malicious ads across the bidstream. RAMP unifies traffic shaping, bid shaping, and flooring into a platform designed for enterprise publisher control and visibility.

Dr. Mark Grether, SVP & General Manager, PayPal, unpacks how PayPal is reshaping commerce media by leveraging its transaction graph across 30 million merchants and 400 million consumers at Marketecture Live. From democratizing retail media for SMBs to monetizing Venmo’s social feed and enabling agentic commerce with trusted payments, this conversation explores why PayPal sits at the center of advertising, AI, and the future of buying online. Takeaways PayPal’s transaction graph spans 30 million merchants and 400 million consumers, giving it a horizontal view that powers audience targeting, market share insights, and closed-loop measurement. The new SMB Ads Manager unifies demand and supply so smaller merchants can both buy previously unreachable audiences and monetize their own site traffic. Venmo’s social feed and Gen Z heavy user base create high demand, upper funnel ad inventory tied to real spending behavior and cultural signals like emoji usage. Honey contributes large-scale intent and catalog visibility, letting PayPal connect discovery to checkout and measure impact even for off-site channels like CTV. In agentic commerce, PayPal aims to be the trust and payments layer that reduces friction while humans still make emotional final decisions.

Scott Spencer, co-founder of Rewarded Interest and former DoubleClick and Google product leader, explains why cookie banners failed, how consumer privacy still feels broken, and what it takes to give users real control without hurting publishers or advertisers. Takeaways RTB wasn’t invented in a single moment. It emerged organically as multiple teams solved latency, bidding, and scale problems in parallel. Cookie banners fail both consumers and regulators by creating friction without real control or understanding. Rewarded Interest aims to replace site-by-site consent with centralized, programmatic privacy preferences across devices. Privacy control likely belongs above the browser level, especially as agentic browsing and AI assistants become mainstream. Changes proposed to GDPR may reduce protections around pseudonymous identifiers, increasing the need for user-centric control tools. The industry risks pushing users toward ad blocking if it can’t offer meaningful, trusted privacy solutions. Scott’s biggest regret from the RTB era isn’t technical. It’s not taking time to appreciate the magnitude of the transformation and the people behind it.
