Product-Led GrowthPLG
PLG (product-led growth) is a go-to-market model in which the product itself is the main way customers find, try, adopt and buy it. Users start with a free plan or trial, reach value without a sales call and upgrade on their own. Sales joins later, usually for larger accounts that need approvals, security reviews or custom terms.
How PLG works
- A user signs up for a free plan or a trial, often without talking to anyone.
- They reach a first useful result quickly: the moment the product proves its value.
- Usage spreads. They invite colleagues, connect other tools and hit plan limits.
- They upgrade with a card, or the account shows enough usage for sales to step in.
- Expansion follows as more teams in the company adopt the product.
In a product-led model the product does the work a seller would do in a sales-led one: it explains, demonstrates and qualifies. That is why onboarding, pricing pages and in-product prompts matter as much as ads.
PLG vs sales-led growth
| Product-led | Sales-led | |
|---|---|---|
| First contact | Sign-up or free trial | Meeting with a seller |
| Who qualifies the buyer | Product usage | SDRs and AEs |
| Best for | Products that show value fast to one user | Complex buys with several stakeholders |
| Typical deal | Many small self-serve plans | Fewer, larger contracts |
| Main risk | Free users who never pay | High cost per customer |
PLG companies choose how much of the product to give away. The three common entry models:
- Freemium: a free plan with limits, with no end date.
- Free trial: the full product for a limited time, then pay or lose access.
- Reverse trial: the full product for a trial period, then a drop to the free plan unless the user upgrades.
PLG metrics to track
- Activation rate: the share of sign-ups who reach the first useful result.
- Time to value: how long that takes.
- Free to paid conversion: the share of free users or trials who upgrade.
- Product-qualified accounts: accounts whose usage looks like what paying customers did before they bought.
- Expansion revenue and net revenue retention: whether paying accounts keep growing.
Free to paid conversion rate = Sign-ups from a cohort who upgraded ÷ Total sign-ups in that cohort × 100For example, if 1,000 accounts sign up in March and 50 of them have upgraded by the end of June, the March cohort's conversion so far is 50 ÷ 1,000 × 100 = 5%.To define a product-qualified account, look back at accounts that became paying customers and find the usage they had in common before they paid, such as a number of active users or a key feature used. Then flag new accounts that reach the same pattern.
When B2B companies add sales to PLG
Pure self-serve stops working when the buyer needs approval from several people, when security reviews start, or when one account could pay far more than any self-serve plan. Many PLG companies then add a sales team that works the accounts product usage has already warmed up. This hybrid is often called product-led sales.
- Route accounts by usage signals: several active users from one company, plan limits reached, pricing or security pages viewed.
- Enrich those accounts to find the decision maker, who is often not the first user.
- Reach out with context from usage, not a generic pitch.
That outbound layer works like any signal-based outbound. See sales trigger events for timing and lead generation for SaaS companies for the engine around it. For contracts of $50K+ sold to buying committees, a sales-led motion usually carries the deal, even when a free plan opens the door.
