🌯 The Programmatic IO 2025 Publisher Dossier

AdMonsters Wrapper: The weekly ad tech news wrap up
When you think of Las Vegas, you probably don’t think of programmatic, DSPs, incrementality measurement, and brand safety. That's unless you were at AdExchanger’s Programmatic IO conference this week, which dove deep into the programmatic supply chain in the middle of Sin City.

I usually write on the publisher side, so I felt like a secret agent among many brands and agencies. And I got some top-secret publisher intel you can deploy on your next programmatic mission.

Here is my personal Programmatic IO dossier.

Secrets from Sin City: A Publisher’s Dossier from Programmatic IO
File 1: The Buy Side Secrets on Brand Safety

Brand safety is no longer just about avoiding harmful content; it's about fostering meaningful, positive connections with consumers.

Mark Proulx, global director, media quality and responsibility at Kenvue, said, “Brand safety has really expanded from just a checkbox to responsibility, quality, fraud, viability, emissions and attention.”

This evolution moves the industry beyond rigid keyword blocklists toward AI-powered, semantic tools that can understand nuance and context. Rather than just protecting brands, these tools help them build mental availability and favorable associations in consumers’ minds.

Inefficient blocking can lead to significant media waste, sometimes to the tune of millions of dollars. “We’ve been able to generate $4.2 million in cost avoidance,” Proulx noted, by reducing unnecessary blocked impressions. Traditional verification methods often fail to grasp the full context, leading to costly mistakes. To get the most out of every dollar, verification needs to be actively managed and continuously optimized.

But publishers are no strangers to brand safety's stickiness. As Jana Meron, Strategic Advisor, Lioness Strategy, noted at Programmatic IO last year, “It’s time for both advertisers and publishers to face facts and stop letting fear dictate brand safety strategies.”

File 2: The New York Times’ View on Curation

According to Courtney Glaze, VP of revenue operations at The New York Times Advertising, publishers must treat curation as a strategic solution to post-cookie challenges.

Glaze further emphasized that curation is about “solving for volume without relevance” by using first-party data and audience intelligence to create meaningful, targeted segments for marketers.

It’s a way to enhance signal fidelity for buyers, enabling smarter, more effective targeting across curated marketplaces. But, Courtney noted, publishers lack consistent methodology, making it even more important to take a disciplined, audience-first approach.

Glaze said this strategic mindset extends to how publishers value and package their inventory. The New York Times created its own hierarchy—prioritizing direct deals, premium PMPs, and finally, the open market—to ensure inventory is not undervalued or oversold.

Instead, publishers must treat their inventory as a premium asset, using performance data to guide pricing and packaging decisions. Not all curation is created equal, and buyers often struggle to distinguish true value from simple repackaging. That’s why transparency, selective partnerships, and a deep understanding of one’s audience are essential.

“Marketing and publishing objectives are aligned," Glaze said, and programmatic strategies must reflect that shared goal.

File 3: The Challenger Platforms

Google recently suffered a major legal setback with the DOJ's ruling, and other platforms are eager to take advantage of the programmatic opportunity.

Challenger platforms create unique niches to compete with Google’s and Meta’s dominance. LinkedIn, Spotify and Reddit strategically differentiate themselves by leveraging their platform-specific strengths.

Jae O., head of ad product, ads measurement at LinkedIn, emphasized the company’s B2B focus, highlighting how it targets professionals with precise audience insights.

Chloe Wix, global head of product and commercial growth at Spotify, is expanding beyond audio to create more immersive advertising experiences through video and AI-generated content.

Jyoti Vaidee, VP of ad product management at Reddit, points out that their platform offers unique reach, with 40% of conversations about products and services, and 30%-60% of users are not on other social platforms.

Each platform invests heavily in AI to enhance targeting, improve ad creation and provide deeper insights, whether it’s LinkedIn’s professional graph, Spotify’s generative ad tools or Reddit’s community intelligence. The key theme emerging is the need for differentiation.

These challenger platforms create value by offering more specialized, context-rich advertising environments. They’re addressing advertiser demands for transparency, privacy and performance by developing unique ad formats, leveraging first-party data and creating tools that make advertising more efficient and targeted.

As Jae O. said, "it’s about providing not just reach but meaningful, measurable outcomes that go beyond traditional digital advertising approaches.
