<b>Growing users, dying product</b>

A freemium app reported monthly active users climbing every month and raised on that chart. Then revenue growth stalled and no one could explain it.

The clue was a cohort retention curve, which the rising MAU line hid. Each new cohort retained worse than the last: month-two retention had slid from 41% to 23% over a year. Active users only kept rising because acquisition outran the leak. They were filling a bucket that drained faster every month.

They froze acquisition spend and rebuilt the first-week onboarding around the one feature retained users adopted early.

Month-two retention recovered from 23% to 38%, and revenue per cohort finally rose — even as the vanity MAU line briefly flattened.

The lesson: total active users can grow while every individual cohort rots. Read retention by cohort, or acquisition will mask the product problem until it's expensive.
