AI is rebuilding the commercial layer of the internet. In the latest episode of Radical Talks, Firsthand Co-Founder & Co-CEO Michael Rubenstein joins Radical Ventures Partner Molly Welch to discuss why the current advertising model is structurally broken, and why the next era will be defined not by static ads but by intelligent Brand Agents. Drawing on decades of experience helping build the modern advertising ecosystem at DoubleClick and AppNexus, Michael makes the case for why this platform shift is larger than a new format or optimization layer — and what it means for the trillion-dollar market being rebuilt underneath it. The conversation covers: - Why AI changes the relationship between marketers, publishers, and consumers - How Brand Agents create adaptive consumer journeys in real time - Why context is becoming valuable again - What happens when AI intermediates discovery and decision-making - Why the future belongs to brands that own their own AI presence Check out the full episode below 👇
So fun to have Michael Rubenstein on!
Amazing discussion Molly and Michael!
