Growth & retention

Zero-party data

Definition

Information a customer intentionally and proactively shares with you, such as preferences, intentions and context, as opposed to data observed from behaviour or bought from third parties. It is consent-clean and usually more accurate than inference.

Defined in DTC Growth & Retention in the Agentic Era.

How else it gets framed

The same term carries different emphasis depending on the surface it’s used on. Both readings are correct.

Information a customer intentionally and proactively shares with a brand - preferences, use case, fit, intentions - as opposed to data observed from behavior (first-party) or acquired from others (third-party).

Owned channel: A communication channel where you hold the relationship directly, such as email and SMS lists built on explicit consent, as opposed to rented reach (ads) or mediated reach (assistant shortlists). No algorithm re-ranks who receives your message.
Machine-visible trust: The part of your operational performance an AI system can check from data: review content and recency, delivery promises, published return and shipping policies, and support outcomes that become public. Agents can't feel your brand; they can read your record.
Trust transfer: The degree to which a shopper's confidence in the AI assistant that recommended a product carries over into confidence in the brand itself, surviving past the first purchase into repeat behavior. High trust transfer looks like an organic-search-level or better repeat rate; low trust transfer looks like a one-and-done customer who reverts to asking the assistant again next time.
Agent-influenced arrival: A new subscriber whose path to signup included an AI assistant's recommendation, comparison, or summary - on-site (a Brand Agent conversation) or off-site (ChatGPT, Claude, Perplexity, Gemini, Google AI Overviews, or Amazon's Alexa for Shopping). Distinct from organic browsing, where the shopper found and evaluated the brand unassisted.
Post-purchase Brand Agent: A Microsoft Brand Agent (in beta) scoped to post-order conversations — order status, delivery issues, warranty, product care, and returns — with access to live order data and the merchant's enriched catalog.
WISMO: "Where is my order?" — the shipping-status question that dominates post-purchase support volume. Trivially answerable by any system with live access to order and carrier state, which is exactly what most legacy chatbots never had.
