# Frameworks to Validate PMF

A set of methods and tools to measure whether a product has achieved Product–Market Fit. Each framework provides a different lens on retention, satisfaction, and growth.

## AARRR / Pirate Metrics

Acquisition, Activation, Retention, Referral, Revenue. A holistic funnel framework: healthy conversion at each step signals progress toward PMF.

## Growth Accounting Framework

Breaks growth into new, retained, and resurrected users. If retention and organic growth drive expansion more than paid acquisition, PMF is likely present.

## Net Promoter Score (NPS)

Measures how likely users are to recommend your product (0–10 scale). High NPS (30–50+) correlates with PMF and adds insight into customer sentiment.

## Retention Curve Analysis

Track user cohorts over time. A healthy retention curve flattens instead of dropping to zero, showing real stickiness—especially relevant for SaaS and apps.

## Superhuman PMF Engine

Rahul Vohra’s structured method: run the Sean Ellis test, segment 'very disappointed' users, identify their top 3 benefits, and double down to strengthen PMF.

## Sean Ellis Test (40% Rule)

Survey customers: 'How would you feel if you could no longer use this product?' If 40%+ say 'very disappointed,' that’s a strong PMF signal. Simple and widely used.
