In short: A case study is evidence, not advertising. A believable one keeps the specific situation, the real sequence including setbacks, dated numbers and the customer's own voice, even when the name has to go. Without a case yet, describe the method and price the first case study into the first engagement.
Key points
- Specificity is the currency: a recognisable situation beats a generic label like 'a fintech company'.
- Percentages without bases and results without dates signal a case study that is hiding something.
- Ask customers at the moment of success and make approval easy with a short draft and one reviewer.
- Anonymised case studies stay credible if only the name is removed, not the substance.
- A clear description of method with no claimed results is more credible than a vague case study.
A case study is an account of a specific customer's experience with a product or service: the situation before, what was done, and what changed. Buyers ask for them because they want evidence from someone like them. Companies produce them badly because they treat them as advertising rather than evidence.
What a believable one contains
A specific customer, in a specific situation. Who they are, what they were dealing with, why it mattered, and what they had tried. Specificity is the currency. "A fintech company" is decoration; "a consumer lender with two rejected ad accounts and a launch in eight weeks" is a situation the reader can recognize.
What was actually done. The decisions, the sequence, the things that did not work. A case study in which everything went to plan reads as fiction because the reader knows nothing does.
What changed, with numbers and a time frame. Before and after, over what period, measured how. Percentages without bases, and results without dates, are the marks of a case study that is hiding something.
The customer's own words, on what they doubted, what surprised them, and what they would tell someone in their position. A quotation approved by their communications team about being "delighted to partner" is not that.
What it cost, or at least what it took. Time, money, effort, disruption. Buyers discount any result presented without its price.
Why most are not believed
They are written by marketing about a customer who has been made anonymous into meaninglessness. The results are extraordinary and undated. The quotation is corporate. Nothing went wrong. And the reader knows the company chose its best outcome and left out the rest.
Believability comes from the things a company is tempted to remove: the setback, the limitation, the number that is good rather than astonishing, the customer's actual voice.
How to get customers to agree
Ask at the moment of success, not months later. Offer them something: visibility for their team, a co-authored piece, a speaking slot, an introduction. Make approval easy: a short draft, a single reviewer, a clear scope of what will be said. Offer the anonymous version as a fallback, and mean it. And build the case study into the engagement from the start, as a deliverable with a scope, so that it is expected rather than requested.
The version that works without a name
Many customers in regulated or competitive categories cannot be named. An anonymized case study is still believable if it keeps everything except the name: the situation in full detail, the sequence, the numbers, the time frame, the setbacks, and a quotation attributed to a role. What kills anonymized case studies is anonymizing the substance along with the identity.
A pattern piece, drawn from several similar engagements, is a further step: "across four companies in this situation, this is what we found." Honest about being a composite, it can be more useful than a single named case, because it describes what usually happens.
For a company that does not have one yet
Say so, and describe the mechanism instead: what would be done, in what order, with what expected evidence at each step. A clear description of method, with no claimed results, is more credible than a vague case study, and it is the honest position for a new offering. The first real engagement should be priced with the case study as part of the scope, so the second buyer has what the first did not.
lowob takeaway: A case study is evidence, not advertising. Keep the specific situation, the real sequence including setbacks, dated numbers, and the customer's own voice, even when the name has to go. Where none exists yet, describe the method and price the first case into the first engagement.
Common questions
What makes a B2B case study credible?
A specific customer and situation, what was actually done including what did not work, before-and-after numbers with a time frame, the customer's own words, and what it cost.
Can a case study work without naming the client?
Yes, if it keeps everything except the name: the full situation, sequence, numbers, time frame, setbacks, and a quotation attributed to a role.
How do I get customers to approve a case study?
Ask at the moment of success, offer them something in return, keep approval simple, offer an anonymous fallback, and build the case study into the engagement scope from the start.
What if my company has no case studies yet?
Say so and describe the method: what would be done, in what order, with what expected evidence at each step.
