tellfilm was founded in 1997 by Stefan Jäger and Markus Kaeppeli under the name handsUP! Film Production. In 1998 the GmbH produced their first feature film Misguided Angel, which was shot in the USA and sold worldwide. When actor Stefan Gubser joined the management in 2007, the company was restructured and renamed tellfilm.

Katrin Renz has been working for tellfilm as a producer and dramaturge since November 2007, and has been managing director since 2014, when Stefan Gubser left the company. In February 2020, Danielle Giuliani joined tellfilm as another producer and partner.
