The founding day of Roblox was September 1st 2006.
The founders were David Baszucki and Erik Cassel. Telamon and Matt Dusek joined the team soon after Roblox was founded.
The first couple hundred builders of Roblox were all developers, investors, testers, and friends of the founders. It's hard to say who the first player of Roblox was, since some of those early accounts are still active.
Our project straddles several rapidly-developing aspects of internet entertainment: virtual worlds, casual gaming, and player-constructed content. Roblox is free to play and safe for kids aged 4+. Our product remains under development and changes to the site and product happen frequently. We deeply value community feedback as we continue to make Roblox into a game that will excite the imagination of the young and the young at heart. We encourage you to provide your ideas, suggestions and feedback by posting here.
We know that many builders are excited about the idea of visiting the Roblox offices. You can read more about going Behind the BLOX by clicking here and scroll to "Tour Roblox."
