GRIMM is a new approach to brand storytelling for the 21st century that focuses on engaging consumers and allowing stories to unfold across multiple platforms. It recognizes that consumers now control their media experiences and seeks to provide an evolving narrative that consumers can pull together themselves from different touchpoints. The approach involves developing a strong brand story, understanding target audiences, and using transmedia planning to tell the story through different channels in a way that generates communities where consumers share and contribute to the brand narrative. GRIMM aims to be the designer and enabler of modern brand stories through bringing together storytellers, strategists, creatives and researchers to craft the best story and most effective way to distribute it.
