I’ve reviewed enough pitch decks to notice something: the biggest fundraising problems are often not bad businesses—they’re small gaps in the story that create doubt.
A market may look huge, but the entry point isn’t clear. Traction may look impressive, but its quality isn’t obvious. A forecast may look ambitious, but the numbers don’t clearly connect to the business underneath.
None of these automatically make a company a bad investment.
But they create questions—and every unanswered question adds friction to the investment case.
So I put together 10 pitch deck mistakes I repeatedly see when reviewing decks.
Not from a design perspective.
From an investor-readiness perspective.
If you’re preparing to raise, run through these before sending your deck to investors.
Which one do you see most often?

🚀 Recent Work | Pitch Deck Design for Apollo Instruments
Recently completed a pitch deck for Apollo Instruments, transforming a complex business story into a clear, structured, and visually engaging presentation.
The goal was to create a deck that communicates the company’s vision, products, market opportunity, and value proposition with confidence while keeping the presentation easy to follow and compelling for its intended audience.
I focused on building a strong visual narrative through thoughtful layouts, information hierarchy, consistent typography, and a polished visual system making sure every slide contributes to the overall story rather than simply presenting information.
Project: Apollo Instruments
Services: Pitch Deck Design • Presentation Design • Visual Storytelling • Information Design • Art Direction
Another project where strategic design helped turn information into a presentation with a clear story and strong visual impact.

CrowdStrike Investor Pitch Deck Design
Presenting a bold, high-impact Corporate Overview deck inspired by CrowdStrike's brand identity — clean red & black theme, sharp geometric visuals, and data-driven storytelling.
This deck covers:
📌 Company snapshot & Q3 highlights (record revenue growth, ARR, profitability)
📌 Category-defining cloud platforms timeline (1999–2011)
📌 The Problem — $100B cyber threat landscape
📌 AI-native XDR platform overview
📌 Financial overview & $225B TAM breakdown
📌 CrowdStrike Store & partner ecosystem
📌 Power of the platform — module adoption stats
A perfect example of how strong visuals + structured data can turn a corporate overview into a compelling brand story. 🚀

At CRITER.AI, we’re building AI that helps migrants avoid expensive legal mistakes and visa bans by auditing Australian visa applications against immigration law. We’ve been getting a healthy amount of investor interest, but there was one recurring piece of feedback: our pitch deck was lackluster.
Fair enough. As a lawyer, my creativity usually goes into finding the legal issue everyone else missed, not deciding which shade of blue says “invest now.”
So we set out to change that. We chose Contra over its competitors because the caliber of people looked considerably stronger.
When I posted our request for a pitch-deck redesign, I expected a few people to reach out with quotes. As of today, we have had 303 applicants.
For a bootstrapped business, working through that volume was simply impossible. So we created a challenge:
“Here is my pitch deck. Pick the slide you think needs the most work, and show me what you can do.”
What followed was fascinating.
101 applicants (around 1/3) never replied. Of those who did, around 10% simply reiterated what they had already said. One person replied that, with 250 applicants, they were not going to bother trying. lol.
Several asked whether the test would be paid. 12 sent a quote for the work to be paid first, after which I could decide whether to go further.
Less than 25% of the applications were obviously AI-generated. We are by no means AI-phobic, but the Claude watermark was perhaps a little too much. You know who you are dude!
2 people had trouble opening the Google file we sent. I’m still not entirely sure why.
7 people were so impressed by the work they did that they watermarked it, labelled it “draft,” or otherwise made it impossible to download for further review.
12 people reached out through LinkedIn rather than the app; a further 18 emailed; and 1 person even called me.
18 people not only sent an example slide; they also signed up for our free immigration-advice beta test.
From 303 applicants, we narrowed the field to 15 people who were simply too good to ignore.
Every one of those candidates took the time to understand what we were trying to do, what CRITER.AI is about, and spoke to us as people rather than as another job listing. Two spotted mistakes in the pitch deck that we would not have noticed without them. Another created a 3-minute Loom presentation explaining the changes they made and why they mattered. Most went beyond the requested single slide. One applicant redesigned the entire pitch deck and sent it watermark-free.
It was a difficult decision, but the person we chose had just that little bit more talent than an exceptionally strong group. They not only showed that they understood what we wanted and impressed us with the slide they redesigned; they also suggested another slide we had never considered relevant, then created it using information we had not even provided.
They took our AI immigration-law business and made our pitch deck speak to investors on a human level.
Can't wait to come back to resign our website, social media and other design work.
Lovely and impressive!
