The Dual-Journey Model of Marketing in the Agentic Era
What changes when AI agents become the first audience for B2B brands — and the mechanism by which the human journey programs them.
Marketing has been built around one journey for sixty years. That journey is splitting in two.
When a B2B buyer delegates research and shortlisting to an AI agent, the agent walks in with a stored preference — something the buyer said in passing weeks earlier, something the agent retained, something the buyer may not even remember saying. The agent is not a neutral evaluator. It carries the buyer's prior brand experience into every comparison it makes on their behalf.
This paper names that mechanism as agent bias and the window in which it forms as the pre-delegation layer. Both are already operating in production systems. Perplexity stores favorite brands as structured preference data. Mem0 retains behavioral patterns across sessions at a benchmarked 26% accuracy gain. Amazon AgentCore extracts semantic preference facts and applies them to future recommendations. The buyer's journey did not end at purchase. It now feeds the agent's memory.
What has not yet been theorized is the mechanism connecting the two — human and algorithmic audiences — and its strategic implication: the human work has to happen first, because it is the upstream that programs the agent. From the paper, Section 5
A February 2026 Harvard Business Review article identified the gap explicitly: marketing must adapt to a customer that may be a machine with its own decision logic, but the mechanism connecting the two audiences had not yet been theorized. This paper, posted the following month, names that mechanism.
