- Approve once, use everywhere
The paths you're weighing
Three ways B2B case studies get made
All three can work. The honest question is what each one actually costs, and what's still your job when it's done.
Do it yourself
Genuinely works if you have the customer relationship and the calendar space. The cost was never the writing — it's the chase.
Freelancer or agency
Professional case study writers produce good prose. The interview, the consent trail, and the approval chain usually stay on your side of the line.
With Proofmap
The whole motion, on the same platform our ongoing clients run their proof on. You bring one happy customer.

How the engagement runs
The bottleneck in a case study was never production. It's the gaps — the weeks between the interview and the draft, the draft and the review, the review and the answer. Those gaps are self-inflicted, and this is how we take them out.
- 1
The interview
One conversation, on video, on the record
We run it, and consent is handled in the session rather than chased afterwards — so you're never the one asking a customer you like for a signature.
- Interviewing customers is what we do — and a neutral third party gets candour an account manager rarely does.
- Shot to be cut, not salvaged — the footage is usable because it was filmed to be.
Prefer to run the interview yourself, or sitting on a recording you never used? Tell us on the call — we can often take an existing interview into the same process.

Production
The platform does the heavy part
The interview goes into the Proofbase, which ranks the quotes by which ones will actually move a buyer. Our MCP then puts Claude and ChatGPT to work against them. The models aren't the advantage; what we point them at is — everything stays in your customer's voice because it's built from what they said.
- Storyboarding runs off the ranked quotes and routes straight to our video editing team.
- Take the design into your own CMS, or take the HTML already built and ready to embed.
- 3
Approval
A portal, not an email thread
Your customer gets a link: every quote awaiting sign-off, where each will be used, and every asset built from them — in one place, with a full audit trail. Not five attachments and a paragraph asking them to check.
- They can hand it to legal or comms with the same link. No account, no forwarding chain.
- Nothing publishes without a recorded approval, and every action is timestamped and exportable.
- Approve once and every downstream format inherits it — reusing a quote next quarter doesn't reopen their review.
The reason this is fast isn't the software — it's that they're reviewing the same week they spoke, while the context is still warm. Most approval cycles die arriving weeks later, when the customer no longer remembers what they said.

The asset set
Everything the interview could give
Delivered ready to publish, every claim traceable to the person who said it and approved it.
- If their brand can't appear, the anonymized version is part of the standard set, not a fallback — the proof survives without the name.
The process moves as fast as your customer can talk to us and sign off. Find out in 30 minutes if that's you.

Buyer's checklist
What to ask any case study writing service — including us
Case study writing services are easy to compare on price and hard to compare on what matters. These five questions separate transcription from proof — use them on us too.
Who runs the customer interview — and is it on video?
The interview is the asset. A writer working from your call notes is doing transcription; a structured interview the customer showed up for, captured on video, is proof — and customers speak more candidly to a neutral third party than to their account manager.
Is every quote approved by the customer — once, in writing?
One-pass approval means the customer signs off on their words a single time, and every downstream format inherits that consent. Anything else reopens legal review every time you reuse a quote.
How many assets come out of one interview?
One conversation should yield the written story, a testimonial video, an approved quote bank, a one-pager, and an anonymized version. Booking a writer and a video service separately means asking your customer twice. If the deliverable is one PDF, the interview was underused.
Can a skeptical buyer trace every claim to a real person?
On-record proof — a named person, on video, who approved their words — is what separates proof from marketing. If the answer is a logo and an unattributed quote, buyers discount it, and so do AI engines.
What happens to the material afterward?
A delivered PDF is the end of most engagements. An interview captured into an indexed, consent-tracked proof base keeps producing — new formats, new campaigns — without going back to the customer.
And the questions people ask us
How much does a case study cost?
How long does it take?
What if my customer says no?
What do you actually need from my team?
We already write our own case studies. Is this still useful?
What if getting case studies made isn't the real problem?
Teams that can't get customer stories out the door usually aren't stuck on the stories. Here's how the pieces fit together.
