Churn
Customers or revenue leaving over time.
What is Churn?
Churn measures how many customers or how much revenue is lost in a period. Buyers care because high churn makes MRR less valuable and can lengthen payback after acquisition.
In Vibe Coding
AI tools often get early trial interest, but churn reveals whether users keep paying after novelty fades.
Example
If 10 of 100 paying customers cancel in a month, customer churn is 10% for that month.
Why this matters
This matters because Churn appears repeatedly when building, deploying, debugging, or connecting services in vibe coding workflows.
When you'll hit this in practice
You will usually run into Churn when working on Customer Concentration Risk.
