Freemium is a pricing model in which one tier is permanently free to use and further features or capacity are paid for. It is not a marketing instrument but a product decision with substantial consequences for cost, support and development.
The two conditions
For freemium to work, two seemingly contradictory conditions must hold at once. The free tier must deliver genuine, standalone value — otherwise it goes unused and builds no user base. And it must have a natural limit that a growing user inevitably reaches — otherwise nobody ever upgrades. A free tier that does too little creates no users; one that does too much creates no customers.
Kinds of limit
Four patterns are common. Limiting by volume — number of projects, records, transactions. Limiting by users, where the free tier suffices for individuals and teams pay. Limiting by feature, where advanced capabilities sit behind the paywall. And limiting by usage intensity. The most durable is the limit that grows with the user’s success: someone using the product more intensively hits the limit because it is helping them — not because something is being withheld.
The cost side
Every free user creates cost: hosting, storage, compute, support, and in AI-adjacent products sometimes substantial processing cost. That cost is real and grows with user numbers, while revenue grows only with the paying share. A freemium model without a cost figure per free user is therefore a risk — particularly where marginal cost per use is high.
How it differs from a trial
Freemium and a time-limited trial are frequently confused and solve different problems. A trial creates urgency and suits products whose value shows quickly. Freemium creates reach and suits products whose value grows with use and which benefit from a large base. Offering both at once usually confuses more than it helps.
When the model does not fit
Freemium is the wrong choice with high marginal cost per user, with support-intensive products, with small audiences where reach has no value, and with products whose value only appears after extensive setup. In those cases a limited trial or a low entry price is the better route.
Practical consequence
Before introducing freemium, two figures belong settled: what does a free user cost per month, and at which concrete limit should they upgrade? Anyone unable to answer the first does not know their risk. Anyone unable to answer the second has no pricing model but a free product.
