MediaPost Planning & Buying Insider Summit 2026
Why this event matters
The MediaPost Planning & Buying Insider Summit is an invite-only gathering of senior media, marketing, and agency leaders focused on the future of media planning and buying. Unlike large-scale conferences, the event brings together a smaller, highly curated group — which makes the conversations far more candid, practical, and useful.
For Atidiv, events like this are where the real signal is. The openness of agency leaders and brand marketers sharing operational realities — not just high-level trends — gives us a much clearer picture of where media and campaign operations are actually headed.
Four themes that defined the floor
AI-driven workflows are reshaping how campaigns are planned and executed.
Across discussions, teams were moving past the "should we use AI" question and into the harder ones — which workflows, which tools, and how to maintain quality at speed.
Audience fragmentation is making media buying more complex, not less.
Creator-led ecosystems, platform proliferation, and shifting consumer behavior are forcing planning teams to rethink how they build and measure reach.
Measurement remains the industry's biggest unsolved challenge.
Multiple conversations returned to the growing disconnect between campaign activity and attributable outcomes — and the pressure this creates on agency-client relationships.
Operational efficiency is now a strategic priority.
As campaign complexity grows across platforms, teams are actively looking at faster turnaround times, better QA processes, and leaner support structures without slowing down delivery.
Who we met
Across the summit, we spent time with agency leaders managing large-scale media operations, brand marketers navigating increasingly complex campaign ecosystems, and platform partners building tools for the next generation of media buying. The smaller setting created space for unusually candid conversations about the real operational challenges teams are facing.
Our take
The gap between campaign complexity and operational capacity is widening.
Most teams we spoke with are running more campaigns, across more platforms, with the same or smaller internal teams — and the cracks are starting to show in QA, reporting, and turnaround times.
Brand-building and performance marketing are no longer separate conversations.
The most sophisticated operators at the summit were finding ways to run both in parallel — and looking for support structures that could flex across both without switching gears.
The agencies best positioned for growth are investing in operational infrastructure now.
Not just tools — but the processes, people, and partners that allow them to scale execution without proportionally scaling headcount.
What this means for you
If you're running a media agency or in-house media team
The operational pressure is real and growing. Campaign complexity is outpacing the capacity of most internal teams, and the cost of slow turnarounds and QA gaps is showing up in client relationships.
If you're thinking about how to scale campaign execution
The agencies ahead of the curve are building leaner, more flexible support structures rather than hiring their way out of the problem.
If measurement and reporting are a pain point
You're not alone. Almost every team at the summit was grappling with the same challenge, and the ones making progress are investing in cleaner processes upstream, not just better dashboards downstream.

Let's talk about what comes next
If any of these challenges sound familiar, we'd love to connect. We work with media and agency teams to build the operational infrastructure that lets them scale without the growing pains.
