Product-led growth (PLG) — where the product itself drives user acquisition, activation, and expansion — has become the dominant go-to-market strategy for B2B SaaS. But PLG is not just a marketing strategy; it requires specific technical capabilities that many organizations don't have in place.
In-Product Analytics
PLG strategies live or die on deep understanding of user behavior within the product. This requires instrumentation far more granular than typical web analytics — tracking specific feature adoption, time-to-value, activation milestones, and usage patterns. Tools like Mixpanel, Amplitude, and PostHog are the foundation of any PLG analytics stack.
Usage-Based Billing Infrastructure
PLG frequently pairs with usage-based billing (pay for what you use), which requires billing infrastructure that can meter usage in real-time, calculate complex pricing, handle overages and upgrades automatically, and integrate billing data with product analytics. Stripe Billing, Orb, and Chargebee are common solutions for this infrastructure layer.
