The company operates a creator-driven model: users upload experiences, which generate revenue through in-game purchases and advertising. Operationally, Roblox faces dual engineering challenges—enabling creators to build with relative ease while maintaining performance, safety, and compliance across multiple jurisdictions. Infrastructure scales across data centers and cloud systems to support low-latency multiplayer gameplay and real-time user presence. The company is headquartered in San Mateo and employs 1,001–5,000 people.
