Answer
Key metrics for measuring product-led growth include free-to-paid conversion rate, time to first value, net dollar retention, trial-to-paid conversion rate, and product-qualified leads. These metrics track how effectively the product drives user engagement, monetization, and expansion without heavy sales involvement.
Free-to-paid conversion rate shows how many users upgrade from free access to paid plans. Time to first value measures how quickly users experience core benefits. Net dollar retention tracks revenue growth from existing customers. High net dollar retention above 100% indicates strong expansion. Tools like Pendo and Mixpanel help companies monitor these metrics and optimize user journeys based on behavioral data.
