About the Marketing Helix
The origin, scope, and purpose of The Marketing Helix as a customer behavior framework.
The model emerged from operational gaps, not theoretical ones.
The Marketing Helix emerged from observed gaps between traditional funnel-based marketing assumptions and measured customer behavior in fragmented, AI-influenced search environments. The gaps were not theoretical: they were operational. Campaigns structured around funnel-stage logic were producing inconsistent results in contexts where customer discovery was non-linear, trust was the primary variable determining conversion, and post-purchase behavior had measurable effects on new customer acquisition that the funnel model did not account for.
The framework was developed in the context of work with franchise brands, professional services firms, and product brands where customer trust, not awareness reach, was the primary variable determining growth. In these categories, customers frequently encountered a brand through peer recommendations, third-party reviews, or algorithmically surfaced content before any intentional brand-level awareness activity had reached them. The funnel's assumption that brand-controlled awareness precedes consideration did not match what was actually occurring.
The Marketing Helix was developed to describe these dynamics accurately, without the prescriptive overlay of a tactical framework. It does not tell practitioners what to do. It describes what is happening: and why alignment, when it occurs, produces selection while misalignment does not.
Market in Motion
The market is not a single customer: it is many customers, all moving at once, each on a different orbit. The same message sits far out from one, closer to another, and close to a third. Marketing is not a campaign aimed at one stage; it is a field condition maintained across all of them.
A descriptive lens, not a predictive formula.
The Marketing Helix is a descriptive model, not a prescriptive one. It identifies conditions (trust, relevance, timing), describes a mechanism (signal gravity), and states a consequence, that alignment is temporary and therefore has to be managed continuously, without specifying which tactics produce those conditions or what measurement systems should be used to track alignment frequency. The model is intentionally agnostic about channels, budgets, and industry categories.
The framework has no controlled empirical basis in the sense of a randomized experiment. Its claims are supported by the consistency of observed patterns across different brand categories and customer behavior research, not by a single definitive study. Practitioners using the framework should treat it as a lens for diagnosis rather than a formula for prediction.
The Marketing Helix is the behavioral layer of a small set of related properties, and the separation between them is deliberate. The Helix explains customer behavior. MarketingOB1 is Mike Millett's online publishing and video channel, where he explains and discusses the framework in plain language. Digilu applies the model through Adaptive Brand Management, with the Observatory as its operational visibility and record. The Marketing Helix explains why adaptation is necessary. Digilu accepts responsibility for doing it. Neither claims to own how customers behave. Questions about the framework's application may be directed to Digilu: see the contact page for details.

Gravity Well
The sheet bends into a well around the customer at its center. A message that carries trust, relevance, and timing comes closer with every turn; one without them drifts past. As trust, relevance, and timing accumulate, the customer moves closer. The customer remains in motion. The pull is not built by the marketer; it forms where alignment has been earned over time.
Developed in practice, then written down.
The Marketing Helix was developed by Mike Millett, who founded Digilu in 1999, joined Stratus in April 2022, and served as VP of Marketing through March 2026. The model came out of more than thirty years of brand, reputation, search, and growth work across franchise systems, professional services, product brands, and nonprofits, where the same pattern kept appearing: alignment with a customer is earned, temporary, and has to be re-earned.
His online essays and videos about the framework are published through MarketingOB1, and Digilu applies it commercially through Adaptive Brand Management. The separation is deliberate: Marketing Helix describes the behavior. MarketingOB1 publishes his online explanations and commentary. Digilu applies the thinking commercially.
