How to Write a Mini Case Study for LinkedIn

I worked with an entrepreneur who had spent 28 years in tech, but he had little confidence in his writing.

He hadn't finished high school, and that sat in the back of his mind whenever he wrote publicly. He worried about grammar, but more than that, he worried that trying to sound "professional" would make him sound fake, or in his words, like a wanker. 😂

So the challenge wasn't to make him sound more polished.

It was to help him sound more like himself.

Six months later, I could hear him

After around six months of coaching, I started noticing the change. The quirks were there. The humour was there. His funny spin on stories was there. Sometimes the typo was there too.

Good.

He hadn't transformed into a professional writer. He'd become more confident communicating what he already knew, and people responded to him.

That's a case study. No giant revenue screenshot required.

A case study needs change, not necessarily a huge number

People often associate case studies with 300% growth, 10x leads or million-dollar launches. Use those numbers when they're real and relevant, but a case study is evidence that something changed.

Before: 28 years of expertise, little confidence writing publicly.

Work: Six months developing his voice and confidence.

After: Writing with humour, quirks and personality instead of trying to sound like somebody else.

Try Before → Work → After → Lesson

• BEFORE: What was happening when you started?
• WORK: What did you change or work on?
• AFTER: What's different now?
• LESSON: What should the reader understand?

Don't polish the human out of the story. Sometimes the interesting result isn't a number; it's a person becoming more capable, confident or recognisable.

If the change you're describing is about how someone communicates or shares what they know, our guides on communicating clearly and sharing your expertise without sounding like a know-it-all go deeper on that specific shift.

Your turn

Think about one client you've worked with and forget the biggest number for a moment.

Ask: What was different after we worked together?

Then write: Before → Work → After → Lesson.

Frequently Asked Questions

What is a mini case study for LinkedIn?

A short post showing real change in a client, using a "before, work, after, lesson" structure. It doesn't need a huge growth number to count.

Do I need impressive numbers for a case study post to work?

No. A case study is evidence that something changed. Numbers help when they're real and relevant, but confidence, clarity or a new skill are valid outcomes too.

What's the Before → Work → After → Lesson structure?

Before describes the starting point, Work describes what changed, After describes the new state, and Lesson tells the reader what to take from it.

How do I find a mini case study in my own client work?

Pick one client, forget the biggest number for a moment, and ask what was genuinely different after you worked together.
