Analytics
定义
Cohort analysis tracks groups of customers who started at the same time (e.g., all customers signed in March 2025) and measures their behavior over subsequent periods. Cohort retention curves reveal whether newer cohorts retain better or worse than older ones — a critical signal for product-market fit trajectory.
要点
- Cohorts defined by start period: monthly, quarterly, annual
- Retention curves plot % remaining over time
- Improving retention curve cohort-over-cohort = improving PMF
- Cohort revenue analysis reveals expansion patterns
示例
Jan 2025 cohort: 100 customers signed. Jan+6 months: 80 remain (80% retention). Jul 2025 cohort: 100 customers. Jul+6 months: 85 remain (85% retention). Newer cohort retains better — positive signal.
