Roblox › Help Center › Roblox History & Company
Roblox looks like a huge corporation today, but it started as a small project by two software developers. If you are asking who made Roblox, who created it or who invented it, the answer is the same: David Baszucki and Erik Cassel.
Key facts at a glance
- Roblox was created by David Baszucki and Erik Cassel.
- Baszucki has led the company as its chief executive for most of its history.
- The platform grew from a small educational physics tool into a global creator platform.
- Roblox is a company, but the games on it are made by millions of independent creators.
Quick answer
Roblox was created by David Baszucki and Erik Cassel. They started work around 2004 on a physics-based sandbox originally called DynaBlocks, renamed it Roblox in 2005 and launched it publicly in 2006. Baszucki remains the public face and chief executive of Roblox Corporation.
Who is David Baszucki?
David Baszucki is the co-founder and CEO of Roblox. Before Roblox he co-founded Knowledge Revolution, a company that built educational physics simulation tools. That background explains why early Roblox put so much emphasis on bricks, joints and physics, and why the platform is still described as a place to build and experiment.
Who is Erik Cassel?
Erik Cassel was Baszucki friend and fellow developer, and the two worked together on Knowledge Revolution before Roblox. He is credited as co-founder and was instrumental in building the first version. Cassel died in 2013, and Roblox has publicly honoured his role in founding the company.
How did they come up with Roblox?
The idea grew out of educational software. Sources describe the founders as wanting an environment where users could both play and create games of their own without needing extensive coding knowledge. The first concept, DynaBlocks, let people build with simple physics-driven pieces and share what they made.
Who invented Roblox?
Inventor is a loose word, but sources consistently credit the pair. You may see a few unreliable pages naming other people or giving wrong details, so check against the founding stories told by reputable outlets and Roblox itself.
Who owns Roblox now?
Roblox Corporation is a public company listed on the NYSE under the ticker RBLX, so it is owned by its shareholders, with the founders holding a stake. Its headquarters are in San Mateo, California. Our page on who owns Roblox covers this in more detail.
Who makes the games on Roblox?
This is a different question. The experiences you play are mostly made by independent creators and studios, not by Roblox Corporation. Roblox provides the platform, tools and payments, and creators build and publish games using Roblox Studio.

Common myths about the creators
One myth says Roblox was made by a famous YouTuber or by a large game studio. It was not. Another says the game was invented overnight. In reality it grew slowly from a teaching-software background and took years to reach a wide audience. A third myth is that Roblox Corporation makes every experience on the platform, when most are built by independent creators.
Why the origin story matters
Knowing who made Roblox explains why the platform is built around creation. The founders came from education technology, so letting people build, test ideas and share them was the point from the start. That philosophy is still visible in Roblox Studio and the Creator Hub today.
How Roblox makes money
Roblox Corporation earns revenue when players buy Robux and spend them on experiences, items and passes. Creators receive a share of what players spend inside their games, which is why many independent developers and small studios build on the platform. Understanding this economy helps explain why the founders focused on creator tools from the beginning.

Timeline of the company
The company began with a small team working on a physics sandbox in the mid-2000s. It spent its early years growing slowly, then added creator tools and a currency system that drew in developers. It later became a public company, and today it serves a very large audience across phones, computers and consoles. The founders vision of a place where people create as much as they play has remained central through each stage.
Who runs Roblox today?
According to company materials, David Baszucki remains the public face of the company and its chief executive. Roblox Corporation employs engineers, safety teams and community staff, but most experiences on the platform are built by outside creators, from solo teenagers to professional studios.
Did one person make Roblox games?
No. Roblox the platform was founded by two people, while the individual experiences are made by a huge community. That is why quality and themes vary so much from one game to the next, and why the platform publishes creator rules and safety standards that every experience must follow.

- Founder: A person who starts a company, in this case Baszucki and Cassel for Roblox.
