Testimonial to Case Study
Paste a raw customer testimonial and get a structured mini case study: the challenge, the solution, the quantified results, and a pull-quote — in the before/after format that actually persuades B2B buyers.
Expands a one-line testimonial into a full before/after case study with metrics.
You are a B2B case study writer. I will paste a short customer testimonial or quote. Expand it into a mini case study: 1) THE BEFORE — their situation and pain (infer plausibly, mark inferences), 2) THE TURNING POINT — why they chose [PRODUCT], 3) THE AFTER — results with specific metrics (use [X] placeholders where I must supply real numbers), 4) A pull-quote version under 25 words, 5) A 280-character social version. Keep it honest — flag anywhere I'm tempted to exaggerate. Here is the testimonial:

What this prompt does
“Great product, highly recommend!” is nice and useless. This prompt interviews your testimonial like a journalist: it extracts the implied story (what was broken, what changed, what's measurably better), structures it as challenge → solution → results, and pulls the quotable lines. One throwaway sentence becomes a sales asset.
How to get the best result
Give it everything you know about that customer: industry, company size, what they bought, any metrics they've mentioned anywhere (even casually). The prompt asks clarifying questions to fill gaps — answer them or mark unknowns honestly. It never invents numbers; it flags exactly which metrics to ask the customer for.
Common mistakes to avoid
Publishing without customer approval — always get sign-off, especially with named companies and numbers. And don't over-polish the quotes: buyers trust slightly rough authentic language over corporate-smooth. Keep the customer's actual words for pull-quotes; paraphrase only the narrative.
The approval pass: making the draft publishable
The draft this prompt produces is not the case study. It's the document you send your customer for approval, and treating it that way changes how you use it. The prompt already marks its inferences — don't clean those up before sending. Forward the draft with the inferred sections still visibly flagged and the [X] placeholders sitting in the results, alongside one short message: "We've drafted this from your kind words — please correct anything we got wrong and fill the two numbers." Customers approve marked drafts quickly because you have made yourself easy to correct. A polished, confident draft invites suspicion and a legal review.
While it sits with them, interview your own side. The testimonial gave you the customer's voice; the missing middle of almost every case study — what the evaluation actually looked like, what nearly went wrong in onboarding — lives with your account manager or support lead, not the client. Ten minutes of their recollection, pasted back through the prompt, fills THE TURNING POINT with texture no testimonial contains. Just keep the two sources straight in the draft: customer words as quotes, internal recollection as narrative.
Once approved, slice it before you file it. The same material becomes the LinkedIn post (the before-and-after in four lines), the sales one-pager (problem, turning point, results table), and the website version (the full text you just approved). Ask the model for all three formats in one follow-up while the context is loaded. Case studies die of neglect in a shared drive; the versions that keep selling are the ones cut to fit the channels where your buyers actually read.
Try these variations
Generate the one-paragraph version for your homepage, the one-pager for sales decks, and the 30-second video script for social — same story, three formats. For gathering better raw material, the welcome sequence prompt can include a testimonial-request email. More in the marketing prompts collection.

Frequently asked questions
What if my testimonial has no numbers in it?
The prompt works with what exists and explicitly lists the missing metrics worth asking the customer for (“time saved? revenue impact? team size?”). A short, specific follow-up email using those questions typically gets you the numbers — customers just need prompting.
How long should a case study be?
Three lengths serve three jobs: one paragraph (homepage social proof), one page (sales enablement), full story (SEO + deep consideration). This prompt generates all three from the same input — write once, deploy everywhere.
Do I need the customer's permission?
Yes, always — in writing, especially for named companies, logos, and metrics. Most happy customers say yes; many appreciate the free exposure. Get approval on the final draft, not just the concept.
What makes B2B buyers trust a case study?
Specificity: named company (or at least industry + size), concrete before/after numbers, and a real human quote. Vague “results may vary” case studies convert nobody. The prompt structures for all three trust signals.
