With nearly 13 years of experience designing Pitch Decks...I have a LOT of samples to show. Examples below include projects that sold, received development funding, though many I'm not aware how far along in the process they got (sometimes I don't know until I see it airing!)
My design process is dictated by the project and what assets are provided (and look/style references help!). I usually like to see everything before I decide how to tackle things. So there is no set "template," as every project is different. InDesign is my preferred program to build in. And as someone who views a LOT kinds of content (films, documentaries, unscripted/scripted television), you'll also be getting a wealth of knowledge and references to help shape visuals your concept!
While many of my clients have found it helpful to see some of my work, or to see how some pitch decks are supposed to be organized, some still don't know where to start. I can help walk you through the process with a deck consultation to get you from a concept in your head or loosely written down, to a visual deck that you will make you feel excited and confident to pitch!
