īaszucki owns a roughly 13% stake in the Roblox Corporation, the company that owns Roblox, a stake estimated to be worth roughly $470 million as of 2020.

In a June 2016 interview with Forbes, Baszucki stated that the idea for Roblox was inspired by the success of his Interactive Physics and Working Model software applications, especially among young students. It was later renamed Roblox, a portmanteau of 'robots' and 'blocks', in 2005. In 2004, Baszucki, along with Erik Cassel – who worked as Baszucki's VP of Engineering for Interactive Physics – began working on an early prototype of Roblox under the working title DynaBlocks. While an investor, he provided seed funding to Friendster, a social networking service. Baszucki led Baszucki & Associates from 2003 to 2004. Baszucki was named vice president and general manager of MSC Software from 2000 to 2002, but he left to establish Baszucki & Associates, an angel investment firm. In December 1998, Knowledge Revolution was acquired by MSC Software, a simulation software company based in Newport Beach, California, for $20 million. Īs a follow-up to Interactive Physics, Knowledge Revolution launched the mechanical design software Working Model in the early 1990s. In the late 1980s, Baszucki, together with his brother Greg Baszucki, founded the company Knowledge Revolution and developed and distributed a simulation called 'Interactive Physics', which was designed as an educational supplement that would allow the creation of 2D physics experiments. He graduated in 1985 as a General Motors Scholar in electrical engineering. While there, he did a summer internship at General Motors where he worked in a lab focused on controlling car engines with software.

Baszucki studied engineering and computer science at Stanford University. He later went on to host his own talk radio show for KSCO Radio Santa Cruz from February to July 2003. He attended Eden Prairie High School in Eden Prairie, Minnesota, where he was the captain of his high school TV quiz team. As a child, he was interested in dirt bikes, go-karts, and science fiction. Early life and educationīaszucki was born on January 20, 1963, in Canada. He previously co-founded and served as the CEO of Knowledge Revolution, which was acquired by MSC Software in December 1998. He is best known as the co-founder (along with Erik Cassel) and CEO of Roblox Corporation.
