Six adtech founders. One moderator who's been inside the industry for 25 years. No slides, no spin — just the decisions, mistakes, and turning points behind the companies you know.

Adtech is in a genuine entrepreneurial moment. New companies are being built, old ones are being rebuilt, and the window created by AI is moving fast. But the story that gets told publicly is almost always curated — the raise, the launch, the growth chart.
This is the other version.
Six founders — bootstrapped and backed, early stage and scaling, building across every layer of the advertising stack — sit down with a moderator who has been inside the industry long enough to ask the questions nobody asks on stage. No polished origin stories. No highlight reels. Just the honest accounting of what it actually took: the moment it almost didn't work, the decision that changed everything, the cost nobody saw coming.
Corey Ferengul, Managing Partner at Aperiam Ventures and former CEO of Undertone and Magnetic, moderates.
Panel followed by drinks, smoothies, and networking.

The pivot, the layoff, the bet that should not have worked. The moment that never makes the keynote.
Not the keynote version. What founders are building, breaking, and rebuilding right now.
Six founders across every funding path compare what they gained, what they gave up, and what they would do again.
