Southbox Entertainment is an independent motion picture and television production company specializing in finance, co-finance, and development.

We maintain offices in both Los Angeles, CA and Atlanta, GA. However, Southbox was originally founded in 2017 in Philadelphia, PA when Founder and CEO Jon Gosier exited 10 years in tech and venture capital. The name “south box” refers to the company’s origins in South Philadelphia where our first office was a small, non-descript, and boxxy.

A long time lover of film and narrative, Jon began to invest more and more heavily into motion pictures and television.
