Roblox operates a virtual platform where users can learn, work, play, and socialize. The platform is built around a community of developers and creators who use Roblox Studio, a user-friendly design tool, to create engaging multiplayer experiences. It primarily targets audiences under the age of 18, making it one of the leading entertainment platforms for this age group, as shown by its high monthly visits and user engagement. Unlike many other platforms, Roblox focuses on user-generated content, allowing millions of new users to join each month, often through recommendations from friends. The company generates revenue through in-platform purchases and subscriptions, creating a thriving ecosystem for both users and creators.
