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.
