What a buyer persona is actually for
A buyer persona aligns three teams that often live on different planets: marketing, product and sales. Marketing writes for "someone", product builds for "all users", and sales talks to anyone with a credit card. The persona forces a name, face, pain and budget on the ideal customer — and filters out feedback noise from people who will never buy.
How a real persona is built (no inventing)
There's a myth that a buyer persona comes out of a marketing meeting with sticky notes. That gets you a fictional persona, not a useful one. The good ones combine three sources:
- 5-8 interviews, 30 minutes each, with current customers from your best cohort (high retention, good LTV).
- Quantitative data from your CRM and product: role, company size, industry, usage frequency, churn.
- Sales conversations: which objections show up, which sentences repeat at close, the exact words customers use.
Recommended structure (one page)
- Identity: fictional name, role, age, industry, company size.
- Jobs-to-be-done: the main one plus 2 secondary. First-person sentences starting with "When... I want... so I can...".
- Pains: top 3, in their words. If you don't have direct quotes, you haven't interviewed enough.
- Expected gains: what outcome defines success for this person.
- Objections: top 3 reasons they wouldn't buy today.
- Channels: where they look for solutions (LinkedIn, Reddit, podcasts, communities).
- Buying triggers: the event that pushes them to look for your solution.
Example: "Sarah, SaaS founder"
Instead of "startup founders", build something concrete. Sarah is 38, founded a 12-person B2B company, runs all marketing herself with two freelancers, and her trigger is always the same: a new round or a competitor shipping a better page. With that level of detail, landings, emails and sales talk tracks write themselves.
Common mistakes that kill a persona
- Demographics with no job-to-be-done. Age alone predicts nothing.
- Too many personas (more than 3). Usually a focus problem.
- Inventing pains that sound good instead of extracting them from interviews.
- Never updating the file. If your product changed, so did the persona.
- Using real customer names — always fictional, so the team doesn't self-censor.
