AI as a Teammate Not a Party Trick with John Riewerts of Acoustic
Recorded live at eTail Boston, August 10 through 12, 2026.
Ask a marketer what they are trying to do and you will get a phrase back, bring the audience closer to the brand, and it arrives with the easy confidence of something everybody already agrees on, which is exactly why John Riewerts, who leads product engineering at Acoustic, takes it apart before he is willing to use it.
“If you break that down, it really means to get people to consume the goods that that brand is creating and putting in the market, and ultimately in a way that creates a tight relationship,” he says. “Because ultimately you want repeat buyers and a happy consumer.”
Acoustic is a marketing engagement company, and Riewerts frames the entire discipline as two tools and nothing else. Marketers send messages, which becomes campaigning, and marketers listen, which is the harder of the two.
Nobody Tells You They Like You
The listening problem is that the signal never arrives as a statement, so how do you read something nobody ever says out loud?
“No consumer is ever going to send a message to the brand and go, I like you, or I don’t like you. That’s not going to happen,” Riewerts says. “What’s going to happen is they’re going to respond through their actions.”
So the work is reading actions, whether someone engages in the channels you are engaging them on, and whether they are active in your digital footprint or your offline one. Translate that and you arrive at the question Riewerts calls foundational for every marketer, which is who is interested in what I am selling.
Context Is the Whole Argument
Acoustic is releasing Acoustic AI on top of its platform, and Riewerts leads with a caveat rather than a capability.
“Anybody who’s ever used chat or anything along those lines knows that it’s only as good as the context that it has,” he says.
That framing is the point of the product. Acoustic AI writes messages, builds segments, and assembles campaigns, which is table stakes now. What Riewerts is selling is what it gets to read while it does that. A marketer can ask it which products people are interested in but not purchasing, and it combs the data, answers, and then helps build a campaign against that answer with a personalized touch based on the behavioral activity underneath it.
Recommendations Nobody Asked For
The second half of the release is the part Riewerts spends the most time on. Acoustic AI pushes recommendations without being prompted.
“We believe that AI needs to be the best helpful teammate,” he says. “It doesn’t need to be a party trick. It needs to be a genuine teammate that’s helping marketing teams solve problems.”
It runs continuously across the relationships between audience, brand, products, campaign engagement, and incoming behavioral signals, and surfaces things a marketer had no reason to go looking for that morning. Repeat buyers whose repeat buying is slowing down. A rise in people interested in a product that is out of stock. Unsubscribes climbing because of one particular campaign. Consumer fatigue trending up.
Four Pillars and the Single Campaign Problem
Asked for a hot take, Riewerts goes back to structure, and names four pillars, product, campaign, audience, and behavioral intelligence.
“You boil down 95% of questions down to those four pillars,” he says.
His read on the current tooling is that it is good and lopsided. “A lot of great tools out there for marketing automation. But they’re so campaign focused that everything focuses on the campaign. But the reality is, we don’t live in a single campaign world. We live in multi-touch attributions.”
Which leaves marketers needing two things at once. To understand the problem statement, and to act on the insight quickly rather than admire it.
