Brand stories sound fake the moment they say “we believe in changing the world.” Swap the brand name and the sentence still works, which means it tells the reader nothing. Strong stories instead name a specific weekend, a specific tool the founder threw away, a specific customer they failed before they got the product right. The framing matters too: in StoryBrand terms the customer is the hero and your brand is the guide, so even an origin story has to earn its place by pointing back at the reader’s problem. These 12 prompts force that specificity into About pages, pitch decks, and values docs, and they ban swap-friendly abstractions. Pair them with the case study prompts for the customer-side equivalent.
TL;DR
- Copy a prompt, replace every
[placeholder]with one concrete detail (a year, a name, a number), and run it. - Run voice-sensitive prompts (1, 2, 9, 12) on Claude Opus 4.7 — it holds tone across a long brief better. Run angle-generation prompts (5, 6, 11) on GPT-5.5 — it spreads wider across distinct directions. Both default tiers (Claude Pro $20/mo, ChatGPT Plus $20/mo, as of June 2026) handle every prompt here.
- The output is a first draft, not the final story. Cut every line that survives a find-and-replace with a competitor’s name.
- Specificity is the whole game: a year, a person, a thrown-away tool, a verbatim customer quote beat any adjective.
Which model to use
These prompts are short and the stakes are voice, not reasoning, so any current frontier model runs them. The split that matters in practice (as of June 2026):
| Job | Pick | Why |
|---|---|---|
| First-person founder voice, scene-setting, holding tone over 200+ words | Claude Opus 4.7 (Claude Pro $20/mo) | Stays closer to a natural human register and keeps your earlier instructions live across a long output |
| Generating many distinct angles (taglines, anti-positioning, mission variants) | GPT-5.5 (ChatGPT Plus $20/mo) | Spreads wider across genuinely different directions in one pass |
| Long source material (paste 20+ customer quotes, a transcript, a deck) | Either — both ship 1M-token context | Gemini 3.1 Pro (Google AI Pro $19.99/mo) is a fine third option here |
Whichever you pick, paste real inputs. A founder story written from [2-line bg] left blank is exactly the generic mush these prompts exist to kill.
Best for
- About pages and “Why we built this” sections
- Pitch decks (origin slide, mission slide)
- Press kits and founder bios
- Internal values / brand voice docs for the team
- Series-A / fundraising narrative drafting
1. Founder origin in 200 words
My background: [2-line bg]. The thing I kept noticing: [observation]. What I tried first that didn't work: [attempt]. What broke through: [fix]. Write a 200-word founder origin story in first person. Voice: honest, slightly self-aware, ends on the principle I extracted. Ban "passion", "journey", and "changing the world".2. Brand origin scene
Write a 150-word "the moment we knew we had to build this" scene for [brand]. Be specific: where, when, what was said. End on the question we tried to answer next.3. Values manifesto
Our 4 values: [V1], [V2], [V3], [V4]. Write a values manifesto: each value gets a 1-line headline, 2 sentences of explanation, and 1 concrete commitment we make because of it. A commitment must be falsifiable — something a customer could catch us breaking.4. “Why we’re not for everyone”
Write a 200-word "why we're not for everyone" page for [brand]. List 3 types of customers we're not the best fit for, and recommend alternatives honestly.5. Anti-positioning
Most competitors in [industry] do [common practice]. We don't — we do [opposite]. Write a 200-word "what makes us different" section grounded in this anti-positioning. No "best in class."6. Mission statement that doesn’t sound fake
Write 5 mission statement variants for [brand]. Each must name: a specific audience, a specific outcome, and a specific approach. Strip "world-changing" abstractions.7. Brand voice notes for the team
Document our brand voice in 1 page. Include: 3 voice adjectives + opposites, 5 phrases we use, 5 phrases we avoid, 1 paragraph of "in customer support email", 1 paragraph of "in marketing copy."8. Origin story for a pitch deck
Write 3 slides of origin story for a pitch deck: (1) the world we saw, (2) the moment we decided to build, (3) what we've learned since. Each slide: 1 headline + 30-word note.9. About-page intro paragraph
Write 3 versions of the opening paragraph for [brand] About page. Voice options: warm-personal, confident-mission, honest-self-aware. Each 60 words.10. “What we don’t do” honesty section
Write a 150-word "what we don't do" section for [brand]. List 3 things we deliberately do not offer and why. Voice: confident, not apologetic.11. Tagline + 1-line pitch pair
For [brand], write 6 tagline candidates (≤8 words each) paired with a 1-line pitch (≤25 words each) that expands the tagline. Each pair must encode a different angle: outcome-led, audience-led, contrarian, mechanism-led, emotion-led, time-saved. Mark which pair fits an About-page hero vs a deck cover slide.12. Customer-quote-led origin
Below are 5 unfiltered customer quotes about [brand]: [paste]. Pull the 1 line that best names what we actually solved (not what we claim to solve). Write a 180-word brand origin paragraph that ends on that line as the punchline. Do not paraphrase the quote — keep the customer's words verbatim.Common mistakes
- Generic “we believe” statements that survive find-and-replace with any competitor’s name
- Mission statements that work for literally any brand in the category
- No specific scene, year, or person — abstraction is the giveaway
- “World-changing” / “best-in-class” / “passion-driven” — abstraction triggers readers’ filler-detector
- Story written entirely about the founder, with no customer ever appearing
- Values listed without commitments — “we value transparency” with no concrete promise behind it
FAQ
Which model should I use for brand story copy? For first-person, voice-heavy pieces (prompts 1, 2, 9, 12) use Claude Opus 4.7 on Claude Pro ($20/mo as of June 2026) — it holds a consistent register across a long output. For wide angle-generation (prompts 5, 6, 11) GPT-5.5 on ChatGPT Plus ($20/mo) tends to spread across more distinct directions. Both free tiers can run these, just with tighter usage limits.
Will AI-written brand stories feel generic?
Only if you feed generic inputs. The model can’t invent your specific weekend, your thrown-away tool, or your real customer quote. Fill every [placeholder] with a concrete fact first, and the output inherits that specificity. A draft generated from blank brackets is exactly the swap-friendly mush these prompts are built to expose.
Should the brand or the customer be the hero of the story? The customer. In the StoryBrand framework, the customer is the hero and your brand is the guide who hands them a plan. An origin story still works under this rule — it earns its place by explaining why you are equipped to guide them, then gets out of the way. The most common About-page mistake is making the company the hero with “the leader in X” headlines.
How long should a founder or About story be? Short. A 150–200 word origin scene (prompts 1 and 2) plus a one-paragraph About intro (prompt 9) covers most pages. Authenticity matters more than length — the 2026 Edelman Trust Barometer reports roughly three-quarters of consumers expect brands to be authentic, and bloat reads as a cover-up.
Do I have to disclose that AI helped write it? There’s no legal requirement for marketing copy, and a brand story you’ve fact-checked and rewritten in your own voice is yours. The honest move is to treat the model’s output as a first draft, then cut, correct, and re-voice it until it reads like a person wrote it — which is the bar for both readers and search engines.
