Case Study Prompt

What it does

Turns the raw facts of a customer success into a structured case study that sells. A case study is social proof in story form — a future prospect reads about someone like them who had their problem and solved it with you. This prompt organizes your details into the proven arc (the challenge, what you did, the measurable results) and writes it so the prospect sees themselves in it, not just a happy customer they don't relate to.

Write a case study from the details below.

Structure:
- A headline with the result (e.g., "How [Customer] cut X by Y%").
- A 2-3 sentence summary box: customer, challenge, result — for skimmers.
- THE CHALLENGE: what the customer was struggling with before, and why it mattered.
- THE SOLUTION: what they did with our product/service — specific actions, not a feature dump.
- THE RESULTS: concrete outcomes with numbers wherever possible. Include a customer quote if I provide one.
- A short closing that points the reader toward the same outcome (soft CTA).

Rules:
- Write so a similar prospect sees themselves in the challenge.
- Lead with and lean on real numbers; don't inflate or invent them.
- Keep it credible — specific and grounded, not a hype piece.
- Concrete language; cut marketing fluff.

Details:
- Customer (name/industry/size): [who]
- Their challenge before: [the problem + stakes]
- What they did with us: [the solution in action]
- Results / metrics: [numbers — before/after, time saved, revenue, etc.]
- A quote from them (optional): [paste]

How to use it

Collect your numbers first — they're what make a case study convince rather than merely flatter. Before-and-after metrics are gold ("from 6 hours to 40 minutes"), but even directional ones help. The summary box at the top matters because a chunk of readers (especially busy B2B buyers) skim; it should deliver the whole story in three lines so they get the point before deciding to read on.

Always get the customer's sign-off on the final version, especially the quote and any figures. A case study they're proud of becomes a reference; one they didn't approve becomes a problem.

Example output

Headline: "How Brightleaf Studio cut payment delays by 73%."

Summary: "A 5-person design studio was waiting 45+ days to get paid. After switching to automated invoicing and reminders, average payment time dropped to 12 days within a quarter."

Results: "Average days-to-payment: 45 → 12. Time spent chasing invoices: ~4 hours/week → near zero. 'I stopped dreading the end of the month,' says founder Lena Ortiz."

Variations

Short/social version: Add "Also give me a 100-word version and a 3-slide carousel outline for LinkedIn."

B2B/enterprise: Add "Audience is enterprise buyers. Emphasize ROI, risk reduction, and rollout, and keep the tone credible and data-led."

Quote-light: Add "I don't have a customer quote. Write it persuasively without inventing one — lean harder on the metrics and narrative."

Anonymous: Add "The customer can't be named. Write it as '[a mid-size logistics company]' and keep the details credible without identifying them."

Common pitfalls

No numbers. A case study built on adjectives ("amazing," "thrilled") doesn't persuade. Find the metrics, even approximate ones.

Feature-dumping the solution. Prospects care what the customer achieved, not a list of your features. Describe the actions and outcomes.

Inventing or inflating results. A fabricated stat that gets challenged destroys trust and can be a legal problem. Use real, sign-off-able numbers only.

Who uses this prompt

B2B founders and marketers building proof for their sales process, agencies and freelancers showcasing client wins, small-business owners turning a happy customer into a referral engine, and content teams that have the success stories but not the time to write them up. It converts a win into a selling asset.
