In high school he took part in cross-country running, skiing, soccer, and band, served as captain of the school’s quiz bowl team, and graduated from high school in 1981.⁠[1][2]

He later recalled that his two or three years of work after college were not satisfying to him; after trying to analyze a range of career directions with a spreadsheet, he turned to educational software, which interested him more, and wrote early code for Interactive Physics.⁠[4]

Baszucki founded Knowledge Revolution in July 1989 and served as its president. The company developed physics simulation software such as Interactive Physics and Working Model for teaching and engineering design. His brother Greg and Erik Cassel, who later co-founded Roblox, took part in this venture.⁠[3][2][1]

In December 1998, MSC Software acquired Knowledge Revolution. Baszucki then worked at MSC until December 2000, finally serving as general manager. After leaving, he made angel investments, hosted a talk radio show, and traveled with his family in an RV.⁠[3][1]

In 2004, Baszucki and Erik Cassel co-founded Roblox; from March of that year Baszucki served as the company’s president, CEO, and a director. The two developed the platform in a small office in Menlo Park, aiming to let users create and experience 3D worlds together.⁠[5][3][1]

Baszucki recalled that an early concept called DynaBlocks was a 3D puzzle game, and after invited testing almost no one kept using it. The team then spent about nine to twelve months rebuilding the product, shifting the focus to multiplayer interaction and user creation; after opening self-service publishing, they soon saw a marked increase in user creation.⁠[4]

Roblox launched in 2006 and gradually became a platform where creators make content and players take part in experiences. Baszucki also uses the name Builderman on the platform and in public posts.⁠[6][7]

In August 2025, Louisiana Attorney General Liz Murrill filed a lawsuit against Roblox, alleging that it failed to adequately protect children and misled parents in its safety messaging. These are allegations made in litigation against the company and are not equivalent to a judicial finding.⁠[11]

On August 15, Roblox publicly denied intentionally endangering children’s safety, said it had added more than 40 safety features over the past year, and acknowledged that its safety systems are not perfect. The company listed measures including age estimation, parental controls, human and automated moderation, and reporting to law enforcement and child protection organizations.⁠[12]

Ready Player Me, in which Baszucki had invested, was acquired by NetflixNetflixNetflix is a U.S. entertainment company that offers streaming series, films, games, and live programming, headquartered in Los Gatos, California.

Users must complete facial age estimation or an applicable ID verification process to get chat access; the platform then limits communication by age group and adds a parental consent requirement for children.⁠[14]

On January 19, 2026, Frame, a platform that uses Ready Player Me, announced that Ready Player Me had said it would shut down its service on January 31; Frame therefore planned to turn off the corresponding avatar editing features while keeping users’ existing avatars. This was a subsequent change to the portfolio product’s public service and does not mean that Baszucki’s personal investment return has been disclosed.⁠[15]

On April 15, 2026, the Nevada Attorney General announced a legal agreement with Roblox. The company committed $10 million to support offline activities and education for children and to strengthen age verification, parental controls, and limits on communication between adults and minors; it also committed to supporting public safety awareness and law enforcement liaison work.⁠[16]

During the 2026 developer conference, Baszucki announced plans including Roblox Everywhere, letting creators further publish experiences in forms such as standalone apps. Browser support was expected to launch in late 2026 and offline support was planned for mid-2027, both part of the roadmap announced at the time.⁠[6]
