Rules for writing personas and buying contexts that produce useful AI research. A persona is who the model is asked to be. A buying context is the moment they're asked about. The most common failure is writing buying contexts as categories ("SOC2 compliance") instead of situations ("First SOC2 attempt to unblock an enterprise prospect"). Categories are always true and trigger nothing. Situations describe what changed.
A persona is one of the distinct buying paths into the user's product. Different buying motions → different personas. Same triggers + outcomes → one persona. Most companies need 2-4. For multi-audience businesses, build parallel persona stacks with at least one persona per side. Two patterns: (1) B2B distribution + B2C consumer (insurance, CPG, healthcare): one B2B set, one B2C set. (2) Two-sided marketplace, network, or platform: retailers and brands (Faire), candidates and employers (job platforms), borrowers and depositors (lending), buyers and sellers (Etsy). Weight by commercial reality (lending often skews borrower-heavy; marketplaces vary).
Title: The First-Time Compliance Builder
Role: Head of Security at 50-500 person SaaS companies
pursuing their first SOC2 or ISO 27001
Role = role type at plural organizations with one or two qualifiers (size, stage, specialty, geography). Three or more qualifiers stacked makes the persona unwieldy. The same person should remain this persona across years.
Title: The HDHP Working Parent
Profile: Late-30s working parents with kids at home,
covered by a high-deductible health plan
Profile = 2-3 stable axes that drive buying for the category. Common axes: life stage, household structure, employment status, primary coverage type, geography, relationship to the category. Pick axes that drive most of the variance for the user's category.
Remove the user's category and competitor names from the Role/Profile. What's left should still describe a coherent person worth reaching.
If the Role/Profile contains "newly," "recently," "post-X," "just-Y," it has a moment baked into the identity. Move the moment into a buying context. The Role/Profile is durable identity only.

Each persona gets 3 buying contexts, ordered most-frequent first. Each is a short phrase (4 to 10 words) naming a discrete moment that puts the persona in market right now.
A category is a permanent feature of the market — always true for everyone in the segment. A situation is what changed for a specific subset this quarter. Categories look like buying contexts but trigger nothing.
Self-test: if your buying context could appear as a feature on a competitor's website, it's a category. Rewrite it as the moment that made the buyer care this quarter.
Strip-the-brand applies here too. Don't name the user's category or solution type inside the situation. "Annual channel planning kicks off; a marketplace bet is up for review" presupposes the buyer is considering a marketplace (the user's category) — rewrite as "Annual channel planning kicks off; needs incremental European reach."
If enterprise framing is wanted, don't write "Enterprise orchestration evaluation." Embed enterprise via role details (CDO, model risk management, Chief AI Officer) and trigger specifics (exec mandate, 5x scale, M&A, security renewal). The research reads enterprise from the situation, not from the label.
In-market test. After this situation fires, is the persona actually in market for the user's product? In underwritten categories (insurance, lending, healthcare), the direct event often disqualifies them — they're calling their existing provider, not shopping. Use adjacent situations: moments where someone close to the persona was hit. Same urgency, no eligibility issue.
Next-action test. What's the literal next thing the persona would do after this situation fires? If it's "call existing provider" or "fight a bill," the situation is too early — they aren't shopping yet. Especially relevant for financial-anxiety situations (deductible spikes, premium increases). Verify the next action is shopping for the user's specific product.
In the Unusual admin: Settings → Personas → Add new persona. Title → Name field. Role/Profile → Description field. Each buying context → one Add buyer context click. Click Create profile. Repeat per persona. Personas don't need to be perfect at submission; the first round of research will surface refinements.
Original submission:
Title: SaaS Marketing VP
Role: VP of Marketing at Series B SaaS companies evaluating AI brand
management platforms with a $150K budget
Buying contexts:
- AI search optimization
- Brand visibility in LLMs
- Currently evaluating vendors
Role: "evaluating AI brand management platforms" names the user's category → leading the witness. "$150K budget" is a third orthogonal qualifier. Strip both:
Role: VP of Marketing at Series B SaaS companies
Buying contexts: all three are categories or ongoing states, not situations.
Re-ordered most-frequent first, the final submission is:

- Annual marketing planning opens; AI search line item is new
