About this project
Cohort retention is one of the most-asked analyses in product / SaaS roles. This project teaches the methodology: cohort definition (signup vs purchase vs first-value), period granularity (day / week / month), and the visualization (heatmap vs survival curves). Use a public dataset or simulate one with realistic decay.
Why build this in 2026?
Retention work is one of the most-protected data analyst skills — judgement-heavy and AI-resistant.
