The Power of a Customer Cohort

One of the central ideas of the book is is the importance of cohorts. A customer cohort is a group of customers who were acquired or born in a specific period, whether that could be a year or a quarter or a month. Once you're a member of a particular cohort, you are a member of that cohort for life. So we do think that there is a kind of a foundational nature of the way that we think about the cube and the lenses that is a whatever other analysis you do. Start with start with the customer base audit because everything else builds upon that.
