Glossary

The language of retention.

The key terms around retention — explained clearly, without jargon.

Retention Operating System

A layer that unites context, decision and execution of retention — the category GRVITY builds.

Retention

The ongoing work of keeping existing customers active and happy — instead of only acquiring new ones.

Churn

When customers stop buying or cancel. The churn rate measures the share over a period.

Lifetime Value (LTV / CLV)

The total value a customer brings over the whole relationship.

Cohort

A group of customers with a common starting point (e.g. month of first purchase) to compare behavior over time.

Segment

A group of customers by shared traits or behavior. With GRVITY living, not static.

Lifecycle

The phases a customer moves through: new, active, fading, loyal, churned.

Onboarding

The first steps after purchase or signup that lead to first value.

Win-back / reactivation

Measures to bring inactive customers back before they're gone for good.

Trigger / event

A customer event (purchase, click, abandon) that can trigger an action.

CDP (Customer Data Platform)

A system that merges customer data from many sources into one profile.

Frequency capping

An upper limit on how often someone is contacted in a period.

Dunning

The flow that follows up on failed payments automatically to avoid involuntary churn.

Hyper-personalization

Content, offer and timing individual per person, not just per segment.

Agentic AI

AI that doesn't just suggest but acts on its own within a set frame.

Source of truth

The one reliable data source all systems refer to — e.g. points in the wallet.

Consent

The documented permission to contact someone over a specific channel.

NPS (Net Promoter Score)

A metric for how likely someone is to recommend a product.

From theory to practice.
