Here's the uncomfortable truth most product marketers haven't internalized yet: your buyer is disappearing.
Not literally — there are still humans making decisions. But increasingly, those humans are deploying agents to do the work that used to land them on your website, in your webinar, or on your SDR's calendar. Enterprise buying teams are building evaluation agents that crawl vendor ecosystems, score capabilities against requirements, and surface recommendations — all before a human ever reads your messaging. On the consumer side, it's happening even faster. Personal AI agents are filtering, comparing, and shortlisting on behalf of people who will never see your carefully optimized landing page.
This isn't a future state. It's the current state, accelerating.
I've spent the better part of two decades writing about the evolving relationship between brands and customers — through the data lens, through the identity and platform lens, and now through what I believe is the most fundamental disruption yet: the moment when "the customer" stops being a person interacting with your brand and starts being an agent acting on a person's behalf.
Everything downstream of that shift changes. And I mean everything.
The Old Frameworks Are Broken
Product marketing has operated for decades on a set of assumptions that feel so foundational we forgot they were assumptions at all. That buyers research by searching. That they consume content linearly. That messaging hierarchy matters because humans process information in predictable patterns. That competitive positioning works because someone is reading your battlecard output in the context of a decision.
When your buyer's agent is the one doing that work, every one of those assumptions collapses.
Think about what a PMM actually does day-to-day. We build positioning. We craft narratives. We enable sales teams. We create launch plans. We obsess over personas. Nearly all of it assumes a human on the other end — someone who can be persuaded, emotionally engaged, anchored by a compelling story.
An agent doesn't care about your story. It cares about structured data, verifiable claims, and capability matching against a requirements set you probably never saw.
This doesn't mean positioning and narrative are dead. It means they serve a different function now — they're for the humans who set the agent's parameters, not for the agent itself. And that's a fundamentally different design problem.
The K-Shaped Future
Here's where it gets interesting — and a little dark.
We're heading toward a K-shaped divergence in marketing teams, and in the workforce more broadly. On one branch, you have the super users: PMMs who've wired agents into their competitive intelligence workflows, who use AI to generate first drafts of positioning docs in minutes, who've built agentic systems that monitor market signals and flag strategic shifts in real time. These people aren't just more productive — they're operating at a qualitatively different level. They see patterns their peers miss. They move faster. They have time to think because the execution layer is increasingly automated.
On the other branch, you have the PMMs still working the way they worked in 2023. Still manually building decks. Still doing competitive research by reading analyst reports one at a time. Still treating AI as a novelty rather than infrastructure. These folks aren't bad at their jobs — many of them are excellent. But the gap between the two branches is widening at a pace that should alarm anyone paying attention.
The uncomfortable implication: within 18 months, the difference between a top-quartile PMM and a median one won't be talent or experience. It'll be tool adoption and workflow design. And that K-shaped curve applies just as much to the buyers as it does to the marketers — the most sophisticated buying teams are already agent-enabled, and they're making the non-agent-enabled sellers' playbooks obsolete.
