Cohort analysis would be incredibly helpful for subscription merchants. Right now, we need a clearer way to understand customer retention by signup month, including how long each cohort stays subscribed, where the biggest drop-offs happen, and how many customers are still active after month 1, 3, 6, 12, etc. For subscription businesses, this is essential because it helps us understand churn, customer lifetime value, and whether changes we make are actually improving retention over time.
