What is freemium?
Also called: free plan, free tier, freemium model, free trial vs freemium
Definition
Freemium is a pricing model where a product offers a free plan with no time limit, alongside paid plans that add more features, usage, seats or support. Free users can upgrade when they need more.
Freemium, explained
Freemium and free trials solve different problems. A free trial gives full access for a limited time, then asks for payment; it works when value is obvious quickly and the product is expensive or complex. Freemium gives limited access forever; it works when the free plan is useful on its own, costs little to serve, and naturally leads some users to need more.
The design question is where to draw the line. The free plan must be good enough that people use it and tell others, but constrained enough that serious users hit a limit. Common lines are usage (projects, documents, API calls), team features (collaboration, admin, permissions), advanced capabilities, and support or security requirements. The best limits correlate with getting more value, so upgrading feels fair.
Freemium has real costs. Free users use servers, storage, support and, for AI products, inference that can be expensive per user. Only a small share usually upgrade, so the free tier has to pay for itself through word of mouth, virality, marketplace visibility or eventual conversions. Model the cost per free user before committing.
It pairs naturally with product-led growth and with launches: anyone who finds you on a launch platform, directory or search result can start immediately. It also helps SEO indirectly, because free users write reviews, tutorials and templates that link back.
Revisit the line as you learn. If almost nobody upgrades, the free plan may be too generous or the paid plan not compelling. If free users churn fast, the free plan may be too limited to deliver value.
Why it matters for founders
A free plan can be your strongest acquisition channel or your biggest cost center. Drawing the upgrade line where value grows decides which one it becomes.
Example
A diagramming tool allows three free boards forever. Solo users stay free and share boards publicly; teams hit the limit within weeks and upgrade. The public boards bring new users from search.
Common mistakes
- A free plan so limited it never shows the product's value.
- A free plan so generous nobody needs to upgrade.
- Ignoring the cost of serving free users, especially with AI features.
