A freemium model is a business strategy where a product or service is offered for free, but with limited features or capabilities. Users can access the basic version without any cost, which helps attract a large audience. To unlock additional features, users can choose to pay for a premium version. This model is commonly used in software applications, online games, and digital services. The freemium approach allows companies to build a user base quickly while generating revenue from a smaller percentage of paying customers. Popular examples of this model include Spotify, Dropbox, and LinkedIn, which offer free access alongside paid subscriptions for enhanced functionalities.
