Category Design
In one line
Category design is the strategy of defining and owning a new category rather than competing inside an existing one — rewriting the market's rules in your favour.
Going deeper
Category design was crystallised in the book Play Bigger. The thesis is blunt: the category leader captures roughly 76% of the category's value. So don't try to be #2 in someone else's category — define a new one and own it.
The canonical examples are Salesforce's 'No Software' and the cloud CRM category, HubSpot's Inbound Marketing, and Drift's Conversational Marketing. None of them tried to be a better version of an existing category. They defined a new one and led it.
Category design is less a marketing campaign and more a whole-company strategy that requires product, messaging and sales to tell one coherent category story. It matters even more under GEO — once AI starts answering 'who's the leader in this category?', the brand that defined the category gets disproportionate upside.
