Product-led growth (PLG) is the GTM motion popularized by Slack, Notion, Calendly, and others. It is often misunderstood as just "have a free trial." Real PLG is structural. Here is the practical definition.
Product-led growth is a go-to-market strategy where the product itself is the primary driver of customer acquisition, conversion, and expansion — rather than relying primarily on sales-led motions.
Hallmarks: self-serve sign-up, free tier or trial, in-product conversion, expansion driven by usage patterns rather than sales upsell motions.
The product can demonstrate value quickly. If first-value takes 90 days of implementation, PLG does not fit.
The buyer can self-serve. If purchase requires committee approval, PLG fights uphill.
Usage data is rich. PLG depends on identifying users who are ready to upgrade based on behavior. Without behavior data, the model breaks.
The market is broad. PLG works best in horizontal categories with many small/mid-size buyers. Tiny niche markets fit sales-led better.
Enterprise-only ACVs ($100K+). PLG can complement sales but rarely replaces it at enterprise.
Complex, configurable products. Custom implementations resist self-serve.
Highly regulated industries. Procurement and compliance reviews break self-serve flows.
Bundled or platform products. Too many decisions for the buyer to make alone.
