The Magic Cohort is the sub segment of customers who represent your a set of customers that have the highest CAC to LTV ratio.
It’s a fallacy to only look at the Magic Cohort because you also spend money on acquiring and servicing all the customers who are not part of the magic cohort.
If I take out the customers that we acquired that only stayed 2 months, then our LTV:CAC ratio is 100 times bigger. 🙂
We frequently use Cumulative CAC to highlight this point.
