Definition

Product-led growth is a go-to-market approach where the product drives acquisition, activation, retention, and expansion through self-serve value.

How to use it

  • PLG needs strong activation and short time-to-value to work.
  • Use cohorts to ensure growth quality: PLG can hide churn if onboarding is weak.

Why this matters

This term matters because small changes compound in SaaS metrics. Use consistent definitions by cohort and segment so you can diagnose retention, payback, and growth quality.
