Brian Gleason wants you to know that cookies are dead.

Dead.

Gone.

Buried next to your retargeting pool and that creepy ad that followed you across the internet like a needy ex.

And in their place? A bold, shimmering, emotionally intelligent AI named Liz—Seedtag’s agentic answer to Freud in a hoodie. She doesn’t just scan keywords; she senses vibes, reads the emotional tenor of a moment, and places your ad next to the perfect piece of content when you’re most likely to laugh, cry, or—ideally—buy.

Gleason’s thesis?

That the real money isn’t in knowing what you did last summer, but in understanding what you’re feeling right now.

He says the opportunity in contextual advertising isn’t just bigger than retail media—it’s $350 billion big, with the emotional punch of a Pixar finale.

Sounds glorious, right?

So let’s break it down—because this is adtech, and we’ve all been burned before.
