Your PLG product has 50,000 signups this quarter. The marketing team is celebrating. But when you look deeper, only 8 percent of those signups ever completed the setup flow. Of those, half never came back after day one. The signup number is a vanity metric masking a product that is leaking users at every stage of the funnel.
PLG requires a different measurement framework than sales-led models. Traditional metrics like MQLs and pipeline value do not apply when the product is the acquisition engine. Instead, PLG teams need metrics that reveal whether the product is actually delivering value, retaining users, and generating organic growth. Getting these metrics right is the difference between a PLG strategy that works and one that just produces impressive signup charts.
The Core Idea
Four metrics predict PLG success more reliably than anything else. Activation rate measures the percentage of signups that reach the product's value moment, the specific action that correlates with long-term retention. Time-to-value measures how quickly users reach that moment. Viral coefficient measures how many new users each existing user generates. And net revenue retention (NRR) measures whether existing customers are spending more over time after accounting for churn.
