Churn cohort
A churn cohort is the group of customers that signed up in the same month (or quarter), tracked over time to measure how many remain. Healthier than aggregate churn because it controls for seasonality and product-version differences.
More detail
Healthy SaaS cohort curves: 90%+ retained at month 3, 80%+ at month 12, plateau above 70% by month 24. Aggressive declines in early months → onboarding problem. Steady decline throughout → product fit issue. Aiprosol's CCO agent monitors retention cohorts weekly; >5% month-over-month decline triggers an exec Slack alert.
