Everyone keeps saying AI will change everything. But how? Here’s one inevitability from our MMA board conversations:   • Ads will be personalized on the fly via GenAI   • Media will be placed and optimized entirely by machines That future is closer than you think, so how do

“We don’t need dogma, we need science.” That’s what I told 𝘌𝘹𝘢𝘮𝘦 during our interview at MMA Impact in São Paulo. Too much marketing still relies on tribal knowledge, legacy methods, and flat-out false beliefs. Ideas are passed down without being tested, and practices are

The best-performing marketing teams have something more than budget or headcount; they have trust. In our MOSTT (Marketing Org Strategy Think Tank) research, orgs with the highest psychological safety shipped 27% more campaigns on time and ran 2.3x more test-and-learn iterations

From counterterrorism to media buying with AI. Yes, really. Mark Polyak isn’t your typical adtech exec. As Chief Product & Technology Officer at MINT, he’s embedding intelligent agents into every layer of the media supply chain and using synthetic data and emerging AI protocols

Let’s be honest... Most marketing events are content dumps or vendor parades. This isn’t that. The CMO & CEO Summit is where the top 100+ marketing leaders meet off-the-record and tell the truth. What’s working? What’s failing? What no one wants to say out loud. If you’re a

Your brain decides whether to pay attention to an ad in 0.3 seconds. Demographics don’t explain that—neuroscience does. That’s the problem with most marketing today. We’re targeting identities, not attention. And then we wonder why performance flatlines. Until we stop guessing

Marketing has gotten faster, flashier, and more automated. But Doug Martin, CMO of General Mills, kicked off our convo with a gut check: Do you actually understand the person you're trying to change? Simple question. Brutal to answer. In this episode of Building Better CMOs,

I have run countless experiments with countless brands, and there has been one constant. Stop targeting based on demographics or past purchases. Start targeting based on propensity. At MMA, we call them the Movable Middles. They are people with a 20–80% chance of choosing your

In a recent MMA Board session, one question stopped the room: How do we build AI-powered personalization that’s accurate, compliant, and still resonates? That’s the tension top CMOs are navigating right now. These conversations are about what it really takes to modernize

Vikrant Batra left his CMO role at HP to build an AI company. That should tell you everything. He saw what’s coming and what most marketers still refuse to face. In this episode of Decoding AI for Marketing, we explore why he made the leap and what it means for the rest of us.

Charlotte Blank, U.S. CMO at Jaguar Land Rover NA, shares a powerful reminder: “Behavioral science is a verb.” It’s not something you know. It’s something you do. You experiment. You adapt. You test again. You get better. Marketing leaders have more tools than ever, but to

Raise your hand! No waiting. No polishing your résumé. Just jumping in and figuring it out later. Lauren Beckstedt did that and ended up running marketing at Brunswick, reshaping the entire organization, and turning boaters into a movement. Curiosity + guts = career rocket

Most marketers say they want better results from their creative. However, many are still stuck in outdated thinking. They are still relying on guesswork, static templates, and generic messaging. At MMA, we ran the data. Real machine learning–driven personalization lifted

AI and compliance don’t have to be enemies. For marketers in regulated industries, AI can feel like an impossible task of balancing innovation with trust and speed with oversight. But it is possible to make it work. On the latest Decoding AI for Marketing, we talk with Steve
