The Data Collaboration Summit
AI-era solutions for the advertising ecosystem
Sony Hall, 235 W 46th St, New York
Oct 23, 2025, 9:30am - 5:00pm
The rules of publishing and digital advertising are being rewritten. With the rise of LLM-driven search, browsers are reshaping how audiences discover and engage with content. This shift is already having a meaningful impact on publisher referral traffic. Yet where there is strong, high-quality data, there is potential for AI to thrive. Unlocking that potential requires the right tools, approaches, and collaboration models.
The Walled Gardens - Google, Meta, Amazon - are proving just how powerful effective collaboration strategies can be. The rest of the ecosystem now faces a pivotal moment: adapt with smarter, data-driven partnerships or risk being left behind.
We're in the Outcomes Era, where the ability to collaborate, activate, and curate data will determine success.
Hosted by Permutive, this Summit is more than a discussion. It’s a demonstration of what’s possible when collaboration is built on direct relationships and a shared ambition to reimagine advertising - raising the performance of the Open Internet to rival, or even outperform, search and social.
Expect candid conversations, breakthrough case studies, and connections that accelerate outcomes. Complete the form to save your spot.
Meet our first confirmed speakers below. Stay tuned, the agenda will be announced shortly!
