In 2009, while living in Las Vegas, Kox worked part-time at a credit union as well as a waitress in order to establish an independent life. Through the service industry, she met her future husband, Rick Barcode, who owned a bar. "Rick said I'm good at technology… [he] and I decided we wanted to do something together. We wanted it to be long lasting and something that we were into." Their partnership resulted in KatieKox.com, a site that specializes in interracial pornography and cuckolding. Kox started to appear in adult movies around 2009.
She has appeared in films for major adult film companies Brazzers, Hustler Video, Adam & Eve, Elegant Angel and Vivid Entertainment, among others. Kox got breast augmentation surgery on March 12, 2009.
