Freemium is a business model in which a company offers a basic version of their product or service for free, while also providing a premium version with additional features or content for a fee. This approach allows customers to try out the product or service at no cost, with the option to upgrade to a more comprehensive version if desired. The term is a combination of the words “free” and “premium,” highlighting the dual nature of the offering. Freemium has become a popular strategy for software and app developers, as well as online services, to attract and retain customers while generating revenue through premium upgrades.
