Product-led growth
Also called: PLG, product-led, self-serve growth, freemium growth
Definition
Product-led growth is a go-to-market strategy where the product itself drives acquisition, conversion and expansion: people sign up, try it and get value before talking to sales, usually through a free plan or free trial.
Product-led growth (PLG) means the product does the selling. Slack, Notion, Figma, Calendly and Canva are the usual examples: you sign up yourself, get value in minutes, invite teammates, and only later pay. Sales, if it exists, comes in once usage shows a team is serious.
How it works
A PLG motion usually has these pieces:
- Self-serve signup: a free plan, free trial or open-source version with no sales call required.
- Fast time to value: the first useful outcome happens in the first session.
- Built-in sharing: the product spreads through use (shared documents, meeting links, invites).
- Usage-based upgrades: limits or team features that prompt payment once value is proven.
The strongest PLG products have a growth loop built in. Reforge's example is Pinterest: users save and share content, Pinterest distributes that content to search engines, new people find it and sign up, and the loop repeats. Calendly is a simpler one: every booking link a user sends shows the product to a new person.
Metrics that matter
- Activation rate: the share of signups who reach the first meaningful outcome.
- Free-to-paid [conversion rate](/glossary/conversion-rate/): the share of free users or trials who start paying.
- Time to value: how long it takes a new user to get the first useful result.
- Expansion: revenue growth from existing accounts adding seats or usage.
PLG tends to lower customer acquisition cost, because many customers arrive and convert without paid sales effort. It can also produce many low-value accounts, so it is not free.
How it plays out on Reddit
PLG and Reddit fit together well. When someone posts "is there a tool that does X?", a reply that says "try Y, there's a free plan, setup takes about 5 minutes" is easy to act on. The reader can check the claim immediately. Compare that with "book a demo", which most Redditors will ignore.
It also raises the bar. Because people can try your product right after reading the reply, the onboarding has to back up what you said. Redditors will report back in the same thread if it did not.
Hacker News works the same way. Its Show HN guidelines ask for something people can actually try, ideally without barriers such as signups or emails. See Hacker News launch.
Common mistakes
- Calling a demo request "free trial". If people cannot use it alone, it is not PLG.
- Gating value behind setup. If the first useful result needs a 30-minute integration, most signups will not get there.
- Ignoring sales entirely. Larger accounts often still want a human. PLG makes sales optional, not obsolete.
Frequently asked questions
What is an example of product-led growth?
Calendly: people sign up free, send booking links, and every recipient sees the product. Teams upgrade when they need shared features.
Is product-led growth only for SaaS?
It is most common in software, but any product people can try before buying, such as a free tool or a sample, follows the same logic.
How does PLG relate to Reddit marketing?
When people on Reddit ask for recommendations, products they can try instantly are easier to recommend and easier for readers to act on.
