Traditional segmentation in business to business markets tends to sort buyers by industry, company size, and geography. That sort is cheap to build, easy to explain, and almost never useful as a commercial tool. The reason is simple. Two companies in the same industry, the same size, and the same country can buy in completely different ways, for completely different reasons, through completely different people.
A buyer archetype is a role in a decision, not a box on a chart
A buyer archetype describes the role the firm is trying to win, the person in the buying organisation who carries that role, the question that person is trying to answer with a purchase, and the signals that person responds to. An archetype is a commercial description, not a demographic description. Two archetypes can live inside the same company and be worth winning separately.
How we build them
- Start with twenty open ended interviews across live buying situations, not hypothetical ones. Hypothetical interviews describe identity. Live interviews describe behaviour.
- Cluster the interviews by the question the buyer was actually trying to answer at the moment of the purchase, not by the company they worked for.
- Name each cluster in the buyer's own words. If the firm cannot find a phrase a real buyer used, the cluster is not a real archetype.
- Test each archetype against at least one purchase that the team did not interview, to make sure the archetype survives outside the training set.
Why this matters for the commercial engine
A well built archetype changes the pricing conversation, the sales conversation, the marketing message, and the product roadmap at the same time, because all four of those levers are actually the same lever pointed at the same person. A segmentation built on industry and size does not change any of those conversations, because industry and size do not describe how the purchase actually happened. The archetype is the unit of commercial work. The segment is a reporting convenience.
