What's a cohort retention curve?

• mygo 7y ago
  define a cohort. Say, people who signed up during a given month = 12 cohorts per year Or people who signed up during a given week = 52 cohorts per year Then, given a set of cohorts, what percentage of people per cohort are retained over time?

    Ah, so basically the GP is saying "your users should be sticking around"?

      At some point, no more users should leave. For example after registration week 1, retain 60%, week 2 30%, week 3 10%, week 4 1%, week 5 0.1%. In that case, you don't have PMF. Unfortunately my numbers look a lot like this :,( But assume week 4 has 10% and week 5 has 10%, that curve flattened out at 10%, and so you have product market fit.
