How to Build a Pitch Deck From Scratch

An investor spends about three minutes on a deck before deciding whether to reply. Everything below is written for those three minutes.

Twelve slides. One idea each. If a slide needs a paragraph to explain itself, it is two slides or it is a conversation.

The twelve

Slide	What goes on it
1. The one liner	What you do, for whom, in a sentence your mother would follow
2. The problem	Whose problem, how they handle it today, what that costs them
3. The solution	What you built. A screenshot beats three bullets.
4. Why now	What changed that makes this possible or urgent this year
5. Market	How you sized it, honestly. A bottom up number beats a borrowed billion.
6. Traction	Revenue, users, retention. Whatever is true and going up.
7. Business model	Who pays, how much, how often
8. Go to market	How the next hundred customers arrive, not the next million
9. Competition	Name real competitors. Saying you have none reads as not having looked.
10. Team	Why you three, specifically, for this problem
11. Financials	Last twelve months and next eighteen. Two charts, no forty tab model.
12. The ask	How much, what it buys, how many months it lasts

The slide most people leave out

Number four. Why now.

Most problems worth solving have been around for years, so the unspoken question in an investor's head is why this was not already built. A good answer is specific: a rule changed, a cost collapsed, a behaviour shifted after the pandemic, a platform opened up.

Without it, a strong deck still feels like it is missing something and nobody can say what.

Traction when you barely have any

Show what you have and do not dress it up. Forty users, twelve of whom came back this week, is a real number and investors know how to read it. A chart with no axis labels tells them you are hiding something, and they have seen that trick a thousand times.

If you genuinely have nothing yet, move team and why now earlier, and be straight that you are raising on the idea and the people. That is a real kind of round.

Practical things that matter more than they should

Send a PDF. Not a link that asks them to sign in.
Name the file with your company name, not "deck_final_v7".
One readable font, big enough to read on a phone, because that is where half of them will open it.
Put your email on the last slide. Founders forget this constantly.

The test before you send it

Give it to someone who does not know what you do. Two minutes, then take it away and ask them to explain your company back to you. Whatever they say is what the investor understood.

Fix the deck until that explanation is right. That is the only feedback loop that matters at this stage.
