The Verticalization Hypothesis is that MMM engines can be shared across industries, but MMM implementations are usually vertical-specific. Different verticals use different structural forms, measure outcomes differently, and require different controls, data, experiments, and decision workflows. As engines become open and interchangeable, commercial advantage will shift to vertical expertise and implementation.

In this essay, I want to convince you that, unless steps are taken, the future of MMM as a robust and commercially viable area for analytical decision-making products is in jeopardy. If the category continues on its current path, MMM risks joining the dust heap of analytics history alongside other once-promising technologies whose commercial claims raced ahead of any practical way to evaluate them before purchase. That’s a bold claim, and bold claims require both disclaimers and evidence. My disclaimers are simple: GDP is a boutique analytics consultancy. We are not selling an MMM product, and we have no intention

Peter Drucker once wrote “The only way to discover your strengths is through feedback analysis. Whenever you make a key decision or take a key action, write down what you expect will happen. Nine or 12 months later, compare the actual results with your expectations. I have been practicing this method for 15 to 20 years now, and every time I do it, I am surprised.” It’s a simple idea, but in practice it’s surprisingly hard to do consistently. People forget what they thought, lose the original context, or never quite get around to doing the retrospective analysis. But

I recently published a blog post arguing that over the next 5 years many commercial MMM engine developers might face an uncomfortable truth: their code and algorithms are not defensible. As part of that article, I separated the “MMM Vendor Value Prop” into four components: I then sketched out an argument that because the first two bullet points are very hard to defend, durable value will move “up the stack” into domain-and-vertical-specific intelligence, operational reliability, and ease of integration (into both other product-based components of the marketing stack and with internal toolchains and processes). Here’s the actual statement: The

Open-source frameworks increasingly provide the estimation, transformations, diagnostics, and optimization required for modern MMM. As those frameworks improve, proprietary engines become harder to defend as a source of lasting commercial advantage.

We walk through seven big bets for the games industry in 2026—from revenue growing while headcount keeps shrinking, to adjacent consumer apps poaching mobile‑game marketers, to AI‑generated ads that are often weirder and more entertaining than the games they promote. I argue that GTA‑6 will reset the conversation about live‑ops, Apple will finally standardize app‑store fees at 15% (with Google close behind), Elon Musk will drag Neuralink into the “ultimate gaming platform” discourse, and the PS6 will slip to 2028.

Understanding advertising effectiveness is crucial for any marketing strategy because it directly impacts resource allocation, campaign optimization, and overall return on investment (ROI). Integrating experimentation into marketing measurement is one of the most effective ways to achieve advertising effectiveness.

Apple will not be able to charge a 27% “tax” on web storefronts that are linked from the game for much longer. This is a huge win for developers but is best understood as part of a larger trend towards government regulation of “walled gardens.”

Want to learn more about revenue optimization in gaming? Join us for the Revenue Optimization in Games Mini-Summit and Happy Hour at 2 PM on March 19 at the American Bookbinder’s Museum in downtown San Francisco. We’re a little over two weeks away from our yearly GDC event (signup here) and I’m really excited. This is our once-a-year community-building event where we take some time to talk revenue optimization with our peers, as a community, and it’s looking incredible. We’ve got a great schedule: That’s an amazing set of speakers and talks. But, to be honest, I’m equally excited by the
