Cohort Analysis
정의
Cohort analysis groups customers by their start period and tracks each group’s behavior (retention, spending) over time, revealing whether the product actually keeps users.
투자유치 시 활용 방법
Investors read retention cohorts before almost anything else: flattening curves signal product-market fit, decaying-to-zero curves signal churn wearing a growth costume.
자주 묻는 질문
Why are cohorts better than average retention?
Averages blend old and new customers, masking decay; cohorts show whether each successive group retains better or worse, which is the real trend.
What does a good cohort curve look like?
It drops initially and then flattens at a stable floor, meaning a durable core keeps using the product month after month.
