SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps teams interpret cohort retention data to find where users drop off, measure retention against benchmarks, and convert those insights into prioritized actions to improve long-term user retention.

Core Features & Use Cases

  • Cohort interpretation: Parse cohort tables or CSVs to compute cohort sizes and retention rates at common intervals (D1, D7, D30, W1, M1, M3).
  • Benchmarking & verdicts: Compare observed retention to industry benchmarks (Lenny Rachitsky, mobile, SaaS, freemium) and give a clear above/at/below assessment.
  • Diagnosis & experiments: Identify the elbow/drop-off point, diagnose likely causes (activation, habit formation, value realization), recommend segmentation cuts, and propose the top 3 actions plus one sprint experiment.
  • Use Case: Given a product analytics CSV, this Skill will summarize retention curves, highlight the sharpest drop, segment by acquisition channel or activation, and output prioritized fixes and an A/B experiment to validate the diagnosis.

Quick Start

Analyze this cohort CSV, compute D1/D7/D30 retention, compare to relevant benchmarks, identify the primary drop-off point, and recommend the top three actions and one experiment.

FAQPage Schema
How do I analyze cohort retention data to find user drop-offs?

To analyze cohort retention data, you parse cohort tables or CSVs to compute cohort sizes and retention rates at common intervals like D1, D7, and D30. This identifies the elbow point where users drop off and highlights retention leaks for further diagnosis.

How do I compare my D7 and D30 retention rates against industry benchmarks?

Comparing D7 and D30 retention rates against industry benchmarks involves evaluating your observed metrics against established standards for mobile, SaaS, or freemium products. This provides a clear above, at, or below assessment to gauge your product's performance.

Can I use a product analytics CSV to calculate retention for weekly and monthly cohorts?

Yes, you can use a product analytics CSV to calculate retention for weekly and monthly cohorts. The analysis requires cohort definitions and measurement events to compute retention rates and summarize curves for mobile, SaaS, and freemium products.

What is the best way to segment cohort retention by acquisition channel?

The best way to segment cohort retention by acquisition channel is to apply segmentation cuts to your cohort tables. This isolates specific channels or activation events to pinpoint where retention curves degrade and diagnose the root cause.

What retention experiments should I run after identifying the primary drop-off point?

After identifying the primary drop-off point, you should run experiments targeting the diagnosed causes such as habit formation or value realization. The analysis proposes the top three prioritized actions and one sprint A/B experiment to validate the retention diagnosis.
