David Baszucki is the co-founder and chief executive officer of Roblox Corporation. He helped establish Roblox in 2004 with Erik Cassel after building software that let people experiment with physics. His role is bigger than making one popular game: he helped create the tools and platform on which other people build their own experiences.
Roblox’s official investor-relations biography identifies Baszucki as founder, president, CEO and a board member since March 2004. The company’s support page names both Baszucki and Cassel as founders.
Who is David Baszucki?
Baszucki is a software entrepreneur and engineer best known for co-founding Roblox. He studied electrical engineering at Stanford University. Long before Roblox became a destination for games, avatars and user-created worlds, he worked on programs that made physics and engineering concepts interactive.
That background helps explain the original approach to Roblox. Instead of designing one fixed story, the early team pursued a system in which people could construct environments, give objects behavior and experiment with how things interact.
What did Baszucki do before Roblox?
Knowledge Revolution and Interactive Physics
Baszucki worked at Knowledge Revolution from 1989 through 1998, according to Roblox’s official executive biography. That company developed motion-simulation software, including the educational product Interactive Physics. Users could place objects in simulated environments and observe what happened when forces acted on them.
The business later developed more sophisticated engineering simulation products. Knowledge Revolution was acquired by MSC Software in December 1998. Baszucki then worked at MSC before returning to new software ideas.
In a Stanford Graduate School of Business interview published May 14, 2026, Baszucki discussed how the lessons from educational simulation influenced his later approach to building Roblox. The connection is not that Roblox is simply a physics textbook: it is that accessible tools can make people curious enough to create things themselves.
How did David Baszucki and Erik Cassel start Roblox?
Baszucki and Erik Cassel worked together on the technology that became Roblox. Cassel had been a lead engineer at Knowledge Revolution, and the two renewed that collaboration while working on an online, physics-based creation environment. Roblox says the company was founded in 2004.
Founding and public launch are different dates. The project existed before the publicly available platform was launched in 2006. Our Roblox founding-versus-launch timeline explains why both 2004 and 2006 appear in answers about when Roblox started.
Cassel was an essential co-founder, not a footnote in a story about Baszucki alone. He died in 2013. Baszucki Group’s account of the company’s history describes their collaboration and notes that Baszucki continues the work in Cassel’s memory.
Why is Roblox different from a single game?
Roblox is a platform for user-created experiences. Players choose from many games and social spaces made by different creators. Developers use Roblox Studio and the platform’s systems to build, publish and maintain experiences that can look and play very differently from one another.
That distinction matters when people ask who made Roblox. Baszucki and Cassel co-founded the platform; they did not personally develop every popular game that now runs on it. Individual Roblox experiences have their own creators, teams, update schedules and rules.
It is also why Roblox changes over time. New safety tools, creator features and game genres may reshape how users experience the platform without changing who originally founded it.
Does David Baszucki own Roblox?
Baszucki co-founded and leads Roblox Corporation, but that does not mean he privately owns every share of it. Roblox became a publicly traded company in March 2021. Ownership in a public company is distributed among its shareholders; the CEO’s job and a founder’s status are separate from owning the entire business.
Claims that he receives every Robux purchase directly or personally owns every game are inaccurate ways to describe how the company and its creator ecosystem work. Likewise, online estimates of a founder’s wealth can change with share prices and are not useful evidence for explaining the company’s origin.
What is Baszucki working on beyond Roblox?
Baszucki and Jan Ellison Baszucki launched Baszucki Group in 2021. The organization describes philanthropic work and research funding, including interests in mental health and other social issues. This is distinct from Roblox’s game platform and should not be mistaken for a feature or product inside Roblox.
