Category design is the practice of defining, developing, and then dominating a new market category instead of competing inside an existing one. The company names a problem the market has not framed yet, names the new category that solves it, and teaches buyers to want that category. The idea was popularized in the 2016 book Play Bigger, whose research found that the category leader captures the majority of the category's economic value.
- Category design builds a new market frame rather than competing for a spot on an existing shelf.
- The term was popularized by Play Bigger in 2016, along with the finding that the category leader takes most of the category's value.
- Salesforce designed cloud software; HubSpot designed inbound marketing. Both set the criteria rivals were then judged against.
- Naming a category is the opening move. The market granting you the category is the result.
- Most companies should enter an existing category, not create one. Category design is a deliberate bet.
In the late 1990s Salesforce did not enter the software market as a better CRM. It attacked the market with a category. The message was "no software," complete with a logo of the word software in a red circle with a line through it. Salesforce was not selling a product feature. It was teaching buyers to want a new frame, software delivered over the internet, and casting every on-premise rival as the old way.
That is category design. Not a better answer inside the existing question, a new question the market had not been asking yet.
Category design is the practice of defining, developing, and then dominating a new market category rather than competing inside one that already exists. The term was popularized by the 2016 book Play Bigger, written by Al Ramadan, Dave Peterson, Christopher Lochhead, and Kevin Maney. Their research made the case bluntly: the company that designs and leads a category, the category king, captures the majority of the category's total market value.
Category design builds the shelf, positioning competes for a spot on it
Positioning places your company inside a frame buyers already carry. Category design builds the frame. It is the difference between arguing you are the best CRM and arguing that CRM should not run on-premise at all.
The reward for building the frame is that you set the criteria. When Salesforce made the argument about cloud software, every competitor had to answer on Salesforce's terms. HubSpot did the same a decade later with inbound marketing. It named the shift away from interruptive advertising, built the category around it, and became the reference point buyers used to judge everyone else. Own the criteria and you own the comparison.
The four moves of category design
Category design tends to run through four moves, in order.
Name the problem
Frame a problem the market feels but has not put words to. The problem, not the product, is what a category is built on. If buyers do not recognize the problem, no category name will stick.
Name the category
Give the solution space a name buyers can adopt and repeat. Cloud software. Inbound marketing. The name has to be sayable, teachable, and different enough from the old frame that it does not collapse back into it.
State the point of view
Make an argument about why the old way is ending and the new category is inevitable. A category without a point of view is a synonym. The argument is what moves buyers from curious to convinced.
Mobilize the ecosystem
Get analysts, customers, and partners to use the category language too. A category is real when other people repeat it. This is the slow, expensive part, and the part that separates a designed category from a clever slogan.
Not every company should design a category
Category design gets romanticized. The truth is most companies are better off entering a category buyers already understand and winning a clear position inside it. Entering is faster and cheaper to explain. Creating costs real time and money to teach the market, and the market can refuse to learn.
Category design fits one situation: the existing frame genuinely misrepresents the problem you solve, so competing inside it means competing on the wrong axis. When that is true, designing a new category can be the strongest move a company makes. When it is not true, it is an expensive way to confuse buyers who already knew where to file you. The difference between category creation and category ownership is the decision underneath this.
Designing a category is not the same as owning one
Here is the distinction the term category design tends to blur. Designing a category is something you do. Owning one is something the market grants back. You can name a category, publish the manifesto, and run the launch, and still not own anything if buyers keep describing the problem in the old words.
Petrichor separates the two on purpose. Category Ownership is the market association you earn when buyers, analysts, and competitors repeat your framing without you prompting it. Category Gravity is the accumulated force that follows: the pull that makes one company the default assumption for a problem, the one people reach for without consciously deciding to. Category design is the opening move. Ownership and gravity are the results, and they are what a growth-stage company is actually buying when it does this work.

Frequently asked
What is the difference between category design and positioning?
Positioning places your company inside a frame buyers already understand. Category design builds a new frame and teaches buyers to want it. Positioning competes for a better spot on an existing shelf. Category design builds the shelf. Category design is harder and slower, and the payoff is that you set the criteria every competitor is then measured against.
Does every startup need to create a category?
No. Most companies are better served by entering a category buyers already understand and winning a clear position inside it. Category design fits when the existing frame genuinely misrepresents the problem you solve. Creating a category costs real time and money to teach the market, so it is a deliberate bet, not a default.
What is a category king?
The term comes from Play Bigger for the company that defines and then dominates a category. The book's research found the category leader captures the majority of the category's total market value, which is why the category king economics attract so much attention. Salesforce in cloud software and HubSpot in inbound marketing are the standard examples.
How do you know if you own a category?
You own it when the market repeats your framing without you prompting it: buyers describe the problem in your terms, analysts use your category name, and competitors sell against criteria you set. Naming a category is a claim. Ownership is when other people make the claim for you.
