The first deck I ever built had 28 slides.

I thought: ā€œThe more detail, the more impressive.ā€
I was wrong.

An investor stopped me after slide 6.
He said: ā€œHold on. I’m still not clear what you actually do.ā€

That stung.
Not because I was rejected (that happens all the time).
But because he was right. I didn’t know how to tell the story of my company.

I crammed everything into one deck: the scrappy pre-seed vision, the seed traction slides, the Series A metrics… all in one Frankenstein presentation.

And here’s the truth:
I’ve now seen 1,000+ decks since, and most founders make the same mistake.
They don’t realize: each stage of fundraising requires a different story.


The pitch deck stack (steal this outline)

Here’s the exact slide order I recommend for each stage.

Pre-seed (10–12 slides)

  • Problem

  • Vision

  • Team

  • Market size

  • Product mockup / demo

  • Roadmap

Goal = sell the dream. Can these founders attack a massive market?


Seed (12–14 slides)

  • Problem + solution

  • Product demo (real screenshots, not mockups)

  • Traction (users, revenue, pilots)

  • GTM strategy (how will you grow?)

  • Team

  • Competition

Goal = show early traction + repeatable growth potential.


Series A (12–15 slides)

  • Metrics (growth, retention, CAC/LTV)

  • GTM engine (not theory — what’s already working)

  • Team scaling plan

  • Market expansion opportunity

  • Financial model

Goal = prove the model works and scales.


Series B+ (12–15 slides)

  • Unit economics

  • Margins & burn profile

  • Market dominance story

  • Expansion roadmap

  • Exit potential

Goal = show you’re building a category winner.


šŸ‘† That’s the cheat sheet.
Keep it simple. Stop mixing stages.

But here’s the thing: a list won’t win you a round.
The difference between a ā€œmehā€ deck and a killer deck comes down to how you tell the story on each slide.

And that’s where most founders trip up.

  • Airbnb → how they made TAM sexy

  • Coinbase → why their traction slide worked with just 3 numbers

  • Canva → the story arc that made design feel like destiny

🚨 The 5 biggest pitch deck mistakes I see every week

  1. Mixing Pre-seed ā€œvisionā€ with Series A ā€œmetricsā€

  2. Product demo that looks like homework, not magic

  3. Competition slides that scream insecurity

  4. ā€œHockey stickā€ revenue projections with no engine behind them

  5. Forgetting the ask slide (yes, it happens)

šŸŽÆ My founder storytelling hacks

  • The ā€œ2-minute investor testā€ → if they don’t get it by slide 2, you’ve lost

  • The single metric that should headline your traction slide (hint: not total users)

  • Why your team slide matters way more than you think at Pre-seed


You don’t need 28 slides. You need the right 12.
