A business model that offers a fully functional product at no cost to the broadest possible audience, then converts a fraction of those free users into paying customers through premium features, expanded capacity, or enhanced capabilities. The economics are counterintuitive: you deliberately serve millions of users at a loss to find the thousands willing to pay.
Also called: Free-to-paid, Tiered free model

How It Works
Freemium is a customer-acquisition strategy disguised as a business model. The company builds a product that delivers genuine, standalone value at zero cost — not a trial, not a demo, but a real product that real people use every day without ever paying. Then it designs a premium tier that unlocks enough additional value that a small percentage of users voluntarily upgrade. The free tier is the marketing budget. The paid tier is the business.
The critical insight is that the free product must be good enough to create habitual usage, but constrained enough to create habitual frustration. This is the central design tension of every freemium business. Make the free tier too generous and nobody upgrades. Make it too restrictive and nobody adopts. The line between "delightfully useful" and "strategically limited" is where freemium companies live or die.
Monetization typically follows one of three patterns.
Feature-gating restricts specific capabilities to paid users — Spotify locks offline listening and ad-free playback behind Premium.
Capacity-gating limits usage volume — Dropbox offered 2 GB free, then charged for more storage.
Audience-gating makes the product free for individuals but charges teams or enterprises —
Slack's free tier limits message history, nudging organizations toward paid plans as institutional memory becomes critical. The best freemium companies combine two or three of these simultaneously.

Paid TierRevenue Engine2–7% of users, premium features, full economics
↑Free users cost ~$0.50–$3/year to serve; paid users generate $50–$300/year
The math is unforgiving. If your free tier costs $1 per user per year to serve and you have 100 million free users, that's $100 million in annual costs before a single dollar of revenue. If 4% convert at $120/year, that's $480 million in revenue — a healthy business. But if conversion drops to 2%, revenue halves to $240 million and the model starts to strain. Freemium is a leverage game: small changes in conversion rate produce enormous swings in profitability. This is why the best freemium operators obsess over conversion funnels with the intensity of a casino floor manager studying table layouts.
