Technical case
We want to create Retention Cohorts to evaluate how we retain users over time. The goal is to
create cohorts starting from the user’s First Transaction Month and check how they retain in the
following months. For example, for all those customers who are New Transacting Users in
January 2023, how many of them retained on month +1 (so, February) and on month +2 (so,
March) and on month +3 and so on.
Build a SQL query to create a retention cohort starting on First Transaction Month for all our
users since inception. Show the result only for Business Accounts. You have the following two
tables:
agents (our users table):
transactions (our transactions table):
Please note that you can use Sheets or Excel or any other visualization tool to end up getting
the desired viz.
