Janzen Madsen was 7 when he first wanted to make video games. He later found Roblox when he was 20 and built an entire business from it.

Roblox is an online gaming platform and a tool for game development created by the Roblox Corporation. It enables users to create games and play those that are made by others.

The company has built one of the top-grossing apps for Apple and Google devices by turning youthful users into game creators without forcing them to learn complicated coding.
