7 mistakes founders make in their pitch deck

Most pitch decks die in the first three slides. These are the seven mistakes pitchd. moderators see in every review queue — and how to avoid them.

Every week, pitches land on the pitchd. board — and every week the same seven mistakes show up. They're easy to make, easy to miss, and easy to fix. Here's the list, straight from the review queue.

1. The deck is a résumé, not an argument

Your background is important; your deck's job is a different one. A deck argues one claim: this specific problem exists, and we are the people who solve it. Every slide should either sharpen that claim or get cut. If a slide doesn't change the reader's decision, delete it.

2. Slides that need a presenter

If the deck can't survive being read alone at 2am, it's not a deck — it's a handout. Investors forward decks without you. Write full sentences in the slide, not fragments that depend on your voiceover.

3. Hiding the ask

The fundraising goal is not a secret to reveal in the final minutes. State it plainly, early: how much, for what, and to what milestone. Vague asks ("we're raising a round") make the entire pitch feel uncommitted.

4. One sentence trying to do twelve jobs

The opening line is not a place for your domain, your technology, your team, and your mission. It's one sentence. Naming a customer and a pain beats naming your stack. If your one-sentence pitch needs a paragraph to parse, rewrite it before touching anything else.

5. Metrics theater

"10x growth" with no denominator, no timeframe, and no definition is not a metric. A single honest number — "we moved $40k through the platform in May" — carries more weight than a wall of invented CAGR.

6. Copy-paste market slides

"Total addressable market: $5B, growing 8% annually" — whose numbers? Generic market slides tell investors you haven't done the work. Replace them with something only you know: the actual price you charge, the actual pipeline, the actual unit cost.

7. No way to check your claims

Every claim invites a click. If you say you have a demo, link it. If you say you have traction, show the numbers. A pitch with verifiable claims and real links is a pitch that gets taken seriously — and it's exactly what the live board is for.

The fix is boring

Most of these mistakes die in a thirty-minute pass where you read the deck out loud, pretending you've never seen your startup. Cut everything that doesn't serve the one claim. Write full sentences. State the ask. Link your demo.

Then put it somewhere public, get the honest reactions, and fix it again. That loop — pitch, feedback, revise — is the one thing no deck template can give you.
