In 2015 Sebastian Martinez and Leo Silkeberg in collaboration with other college students created the film "City Boys"  a movie about a group of Stockholm teens that showcases how male violence affects the social relations of the youth today. Inspired and empowered by the experience the pair started the production company ON NOX PICTURES. 

On Nox has since then worked in collaboration with non-profit organizations, artists and other film producers to create music videos, commercials and TV-series. 2019 the team expanded by adding the project manager and producer Natli Flach to the On Nox family to broaden our managerial and marketing skills.
