About the Company

Roblox

Runs a platform where users build and play games

Roblox runs an online platform where people play, chat, and hang out in 3D games built by its users rather than by the company itself. In 2025, Grow a Garden, a game a teenager made on Roblox, set the record for the most people playing one video game at the same time. Creators build games with Roblox Studio, a free design tool, and players join through the free Roblox app on phones, computers, game consoles, and VR headsets. Roblox makes money by selling Robux, a virtual currency players spend on avatar items and in-game extras, and it shares part of that spending with creators, who can exchange their Robux for real money. Roblox was founded in 2004 and is based in San Mateo, California.
