Crossover Framework
Think of this one like a Venn diagram with a purpose. The Crossover Framework helps you find that one message that really hits—by blending what your brand does best with what actually matters to people. It was popularized in brand strategy and creative planning circles, not attributed to a single author.
It all comes together at the sweet spot between:
Category / Product Insight – what makes you stand out from the competition.
Audience / Cultural Insight – what clicks with people's mindset, habits, or what's going on in the world.
Smash those two together and you get your Single-Minded Proposition — a sharp, no-fluff message that sticks and makes people care.
