What problem does it solve?

This Skill helps teams understand how user retention, engagement, and revenue change over time by comparing cohorts instead of only looking at aggregate metrics.

Core Features & Use Cases

  • Cohort Segmentation: Group users by signup date, acquisition channel, or plan type.
  • Retention Tracking: Measure how cohorts return week over week and compare performance across segments.
  • Insight Generation: Identify the cohorts that retain best and the behaviors that drive long-term engagement.
  • Use Case: A growth analyst can compare free versus paid users across the last quarter to see which acquisition sources produce the strongest week 8 retention.

Quick Start

Analyze the last three months of weekly retention cohorts by signup date and plan type, and summarize the most important retention trends and drivers.

How do I segment user behavior by acquisition channel for cohort analysis?

To segment user behavior by acquisition channel, you group users into cohorts based on their source channel, then calculate their return rates and engagement metrics over time to evaluate which channels drive the strongest retention.

Does this cohort analysis approach work with PostgreSQL data?

Yes, this approach works with PostgreSQL data. You can use your PostgreSQL database to group users by signup date or acquisition channel, calculate return rates, and extract actionable retention insights.

What is the best way to extract actionable insights from cohort retention data?

The best way to extract actionable insights from cohort retention data is to compare week-over-week return rates across segmented cohorts, identifying the specific acquisition channels and plan types that drive long-term engagement.
