Product-led growth (PLG) is a strategy where the product itself drives signups, conversion and spread, through free tiers, trials, self-serve setup and features that invite others.
Instead of a sales call, users try the product, reach value on their own and upgrade when they need more.
Sharing features, public pages and badges let the product spread each time it's used.
Why it matters for a launch
For a solo maker without a sales team, a product that sells itself is often the only scalable option.
