The role, the job, the trigger — not a fictional biography.
A buyer persona names the human in the buying group: role, job-to-be-done, trigger, objections, and what they need to see to say yes. B2B deals have more than one. Economic buyer, user, and blocker are not the same page.
Invented hobbies, stock-photo names, and “values innovation.” If it does not change a page, an email, or a demo, cut it.
As many as there are distinct jobs in the buying group. Start with the economic buyer.
