Alex Balfanz, (born May 5, 1999) known online as badcc, is an American video game developer who is the programmer and co-creator of the Roblox game Jailbreak.

Born in 1999, Balfanz began to code games using Roblox Studio at the age of 9.^[1] Balfanz's father worked as a programmer, which Balfanz cites as one of the main reasons for his early interest in coding.^[2] He attended high school at the Trinity Preparatory School.^[3] Prior to releasing Jailbreak, Balfanz had made several other games on Roblox, which he stated had made him "maybe a couple thousand" dollars.^[3]

In January 2016, Balfanz and his business partner, who goes by "asimo3089", created the game Volt, an open-world game in which players complete minigames.^[3]

In January 2017, Balfanz, along with asimo3089, uploaded Jailbreak, a cops-and-robbers game, to Roblox. On its first day of release, it reached 70,000 concurrent players, a number which Balfanz later said had shocked him.^[1] It quickly became one of the most popular games on the platform, and made Balfanz a millionaire.^[4][3]

Balfanz attends Duke University, where he is able to pay off his college debt using funds from his games.^[2][5] Balfanz has also been a YouTuber since 2011, maintaining a channel with over 100,000 subscribers and seven million views. The content uploaded includes Roblox building and scripting content, custom musical pieces, and showcases of new Jailbreak content.^[6]
