The Slide Type Most Founders Skip
Case study slides are the most persuasive slide type in a deep tech pitch deck and the most consistently absent. They prove rather than claim. This article explains why they matter and how to structure one even at an early stage.
Claims Cost Nothing. Proof Is Rare.
Deep tech decks are full of claims. A breakthrough platform. A category-defining solution. A first-mover position in an underserved market. These claims appear in almost every deck reviewed in every room. They cost nothing to make and they carry diminishing weight with every pitch an investor sits through.
The case study slide does something none of the other slides do. It proves rather than claims. A real-world use case shows the problem as it exists in practice, shows the solution applied to it, and shows the outcome. That's a different category of information from a market sizing slide or a technology overview. It's evidence, not assertion.
One Proof Point Beats Three Claims Slides
One real case study, structured as problem, solution, outcome, does more persuasive work than three slides of market positioning. It's the difference between telling an investor what your company is and showing them what it does.
If you've got a pilot, structure it. If you've got an early customer, document the outcome. If you've got a research collaboration with a measurable result, that's a case study. Most founders sitting on that evidence aren't using it because they're waiting until the traction feels more impressive. Use it now. The investor sitting across from you isn't comparing it to your Series B. They're comparing it to every other deck on their desk that made claims without proof.
How to Structure the Case Study Slide
The framing from Camp Hustle — Hustle Fund's founder bootcamp I attended in San Francisco this year — was clear: use real-world use cases to show the why. Explicitly prove why your company is the one engineered to win the market. Not what you believe about your technology. What actually happened when you applied it to a real problem in the real world.
Case studies also provide the human element that technical decks consistently lack. A specific patient. A specific diagnostic outcome. A specific lab that reduced processing costs by a measurable figure over a defined period. These details are what investors remember after the meeting's ended and they're reviewing six other decks from the same week.
Most founders skip the case study slide because they feel they don't have enough traction to justify including one. This reasoning is backwards. Even a single early pilot, structured correctly, is more persuasive than a full slide of market positioning claims. An imperfect real example demonstrates that the technology's been applied to an actual problem and that the outcome was worth documenting.
The structure is simple. The problem that existed before your solution arrived. What you did. What changed as a result, with specific figures where possible. That sequence moves the reader from claim to proof in three steps and leaves them with a concrete memory of what your company actually does in the world.
Structuring the evidence you already have into a case study that lands is part of the pitch positioning work Marshall Studio does with technical founders. If the proof exists but isn't being used well, that's a fixable problem.
