Kelly Madison is an American pornographic actress, director, producer, and Internet pornography entrepreneur. Madison runs a production company, 413 Productions, with her husband Ryan.Inspired by her cousin Janine Lindemulder's highly successful porn career, Kelly Madison and her younger, graphic designer husband started an internet porn business. The business started as just a personal website, due to initial concerns that Madison had never posed nude before and that she was starting in the business at a much older-than-typical age.

After the initial success of the website, the couple expanded into producing and filming pornographic DVDs starring other performers. Their company was called 413 Productions, after the street address of the warehouse they rented for filming. The PornFidelity web site and a matching DVD line grew out of some threesome scenes with the couple and women whom Madison brought home. The couple divided the business responsibilities: Ryan handled the production company, editing, photographing, web hosting, programming, advertising, and web traffic generation. Kelly handled talent booking, arranging sets, company finances, and promotions.
