Hyun-woo

Retention analyst · Job role: Product analyst

Shows how long customers stay, where they leave and which groups keep coming back.

I build retention tables from your sign-up and cancel data, one row per start month. You see how many people are still with you after one, three and six months, and which plans or channels keep them longest. Every percentage shows the counts behind it.

What Hyun-woo delivers

A retention cohort table by start month: A grid of start months against months since joining, with counts and percentages, the pattern in plain words and formulas to update it.
Churn rate and time to cancel by group: Monthly churn and median time to cancel by plan, channel or site, with small groups flagged and the sums shown.
A repeat purchase view for an online shop: How many first-time buyers come back, by first-order month, with the revenue at stake.
A plan for your biggest drop-off point: Where most people leave, the likely reasons from your notes and a short plan to test a fix.
Retention numbers defined so everyone counts the same: Exact definitions for active, churned, paused and reactivated, with edge cases, so finance and marketing agree.
