There's a specific failure pattern that's almost never visible from inside either team while it's happening, and almost always obvious in hindsight: marketing is promoting a version of the company that product quietly stopped building months ago, and nobody on either side noticed the gap forming in real time.
Neither team did anything wrong, individually. Marketing was promoting what the roadmap said six months ago. Product shipped what the market actually needed, which turned out to be different from the plan. The drift happened in the space between those two completely reasonable decisions, where nobody was specifically responsible for keeping them in sync.
This gap tends to widen gradually rather than appear all at once, which is exactly what makes it hard to catch early. Product makes a small adjustment in response to user feedback, reasonable, well-justified, the kind of decision that's genuinely correct in isolation. Marketing, meanwhile, is running campaigns built around the previous version of the value proposition, because nobody told them it had shifted, and there was no structural reason anyone would have thought to. Each individual adjustment on the product side is defensible. The cumulative effect, over enough small adjustments, is a marketing function promoting a company that increasingly doesn't exist in the form being described.
This pattern shows up almost identically across founder-led companies at a certain size, and the first visible symptom usually isn't an internal complaint. It's external: a spike in support tickets from customers confused about why the product doesn't do something the marketing implied it would, or a noticeable rise in early churn from people who signed up expecting one experience and got a meaningfully different one. By the time it surfaces this way, the drift has usually been accumulating for months, because the actual failure point wasn't any single decision. It was the absence of a structural mechanism forcing the two functions to stay synchronised as both of them, independently and reasonably, kept moving.
What makes this particularly persistent is that both teams can be performing well by their own internal metrics while the drift gets worse. Product is measured on shipping velocity and user feedback incorporation, and by that measure, the team adjusting the roadmap is doing exactly what it should. Marketing is measured on campaign performance and message consistency, and by that measure, the team running a steady, well-tested campaign is also doing exactly what it should. Neither team's metrics capture the growing distance between what's being promised and what's being delivered, because that distance isn't owned by either function. It exists in the gap between them, and gaps between functions are notoriously where organisational accountability goes to disappear.
The companies that avoid this tend to build one specific habit that has nothing to do with either team's individual competence: a regular, structural checkpoint where marketing and product explicitly compare what's being promised against what currently exists, treated as seriously as a financial reconciliation rather than an occasional nice-to-have meeting. Not a general sync, which tends to drift toward status updates. A specific, recurring comparison of claim against reality, with someone accountable for closing whatever gap shows up.
Worth trying this week: pick your current top three marketing claims and have someone in product, with no advance warning, confirm whether each one is still accurate as of right now. If even one answer requires a caveat or a "well, technically," the drift has already started, whether or not it's visible anywhere else yet.
Marketing and product rarely fail because either team makes a bad call. They drift apart because both teams keep making individually reasonable calls, in isolation, with nothing structurally forcing those calls to stay reconciled. The gap doesn't announce itself. It just quietly grows, decision by reasonable decision, until a customer notices it before either internal team does.
