What is a pitch deck, and what goes in one

A pitch deck is a short slide presentation, usually 10 to 15 slides, that a founder uses to explain a business to investors. It holds 11 core slides: cover, problem, solution, market, product, traction, business model, competition, team, financials, and the ask. Its job is narrow: earn the next meeting, not the check.

I have built decks for my own raises and read plenty from other founders. Most fail the same way: the right slides are there, but none of them proves anything. This post gives you the definition first, then goes slide by slide through what each one has to prove and the move that sinks it.

#What is a pitch deck? The meaning in plain words

A pitch deck (sometimes "investor deck" or "startup deck") is the presentation a startup sends or shows to investors when it raises money. It tells the company's story in a fixed order: what is broken, how you fix it, how big it gets, the proof it works, who is building it, and how much you want.

Three things define it:

• It is short. Ten to fifteen slides. Per DocSend's Q1 2024 data, investors spend about two and a half minutes on a deck, so the first read is a skim.
• It reads on its own. Most decks get opened cold, forwarded to a partner, with you nowhere near the room.
• It has one outcome. A second meeting. It does not close the round or replace diligence.

The term shows up outside fundraising too (sales pitches, partnerships, film and TV pitches), but when people say "pitch deck" they almost always mean the investor version. It is not tied to PowerPoint: the deck is the story, and it can live in Keynote, Google Slides, a PDF, or a live link.

#Pitch deck vs. business plan

At the seed stage most investors ask for the deck and never read a formal plan. Write the deck first.

#What goes in a pitch deck, slide by slide?

Eleven slides, each answering one question an investor already has. Here is the whole spine with the detail that carries each slide.

Reorder or drop a slide if your story calls for it. What you cannot do is keep a slide that proves nothing.

#What does each of the 11 slides need to prove?

Cover. Company name, logo, and one line in the "X for Y" shape that survives being forwarded. A mood-board tagline like "Reimagining how teams work" tells an investor nothing about what you sell.

Problem. Someone is in real, expensive pain right now. The number that carries it is a cost: hours wasted, dollars leaked, customers lost. The classic miss is "the market is fragmented and inefficient," which is a problem nobody pays to fix.

Solution. Your product removes that specific pain, and ideally why it is possible now. Lead with the insight in one sentence before any features. A wall of capabilities reads as a product nobody has decided they need.

Market. The company can get big enough to matter to a fund. Build the number bottom-up: how many customers exist times what each pays. "We only need 1% of a $50 billion market" is the fastest way to lose a seasoned investor. My TAM SAM SOM slide guide walks through the math.

Product. It exists and a human can use it. One or two screenshots of the core action beat twelve half-built features or a roadmap to 2030.

Traction. The slide that turns a story into evidence. Show revenue or active users over time with real figures on the axis. "Up 300%" off ten users is not traction; small real numbers read as confidence.

Business model. Money comes in, repeatably. Price times who pays, plus gross margin, payback period, or LTV to CAC if you have it. "We'll monetize later" says you have not tested whether anyone will pay.

Competition. Map the real alternatives, including doing nothing, then name the one wedge you can defend. "We have no competitors" reads as naive, and a 2x2 rigged so you sit alone in the top right reads as spin.

Team. Why you, for this problem. The experience, relationship, or insight that makes you the people most likely to win. At the earliest stage there is little else to underwrite.

Financials. You have thought past the raise. A three-year projection is fine if the few drivers behind the revenue line are on the slide, and if it reconciles with the business model two slides earlier.

The ask. The amount, the milestone it buys, and the runway, like "$2M to reach $1M ARR over 18 months," with a rough use of funds. No ask means nothing to say yes to.

Here is a SaaS pitch deck I built to this order on a sample brand. Click through it: the market slide, the ARR chart, and the $4M ask are each doing one job. The same deck is the SaaS pitch deck template if you want to edit it.

#How many slides should a pitch deck have?

Ten to fifteen. Guy Kawasaki's 10/20/30 rule (ten slides, twenty minutes, no font under thirty points) is the classic ceiling, and Sequoia's outline has ten sections. Past twenty you are explaining rather than pitching. Put backup detail in an appendix after the ask.

#Sequoia, Y Combinator, or Kawasaki: which slide order is right?

They agree more than they differ. Sequoia's published outline runs company purpose, problem, solution, why now, market potential, competition and alternatives, business model, team, financials, and vision. The slide founders forget from it is "why now": the shift in technology, regulation, or behavior that makes this the moment. Y Combinator's advice (Kevin Hale's talk on pitch deck design is the usual reference) puts legibility, simplicity, and obviousness ahead of polish: one plain sentence on what you do, text readable from the back of the room. Kawasaki's 10/20/30 is the constraint that keeps both honest.

Pick one, adapt it, and judge every slide by whether it proves its point. To see how funded companies actually sequenced theirs, my pitch deck examples break down real decks, including the Airbnb pitch deck.

#What should you avoid in a pitch deck?

• Too many slides. Cap it near 12 and move the rest to an appendix.
• Vanity metrics without a baseline. Show absolute numbers.
• Walls of text. One idea per slide, written as a headline.
• A missing or vague ask. Name the amount and the milestone.
• Hiding the risks. Diligence finds them anyway; naming them yourself reads as judgment.

#How do you build all 11 slides without losing a weekend?

The story and the numbers are yours. The build, fighting alignment and brand colors at midnight, is the part I hand off. heydecks is the AI slide creator for AI agents: Claude, ChatGPT, or Cursor writes the copy over the heydecks MCP server, and heydecks renders it into 95 hand-designed slide templates on your brand, returning a live link, a PDF, and an editable PPTX. Connecting Claude Code takes one line:

Then paste your notes and ask for the 11 slides above. The agent writes from what you give it, so the traction slide is only as real as your numbers.

#Frequently asked questions

#What is a pitch deck in simple terms?

It is a short slide presentation, usually 10 to 15 slides, that explains your startup to investors: the problem, your solution, the market, proof it works, the team, and how much you are raising. Its purpose is to get a second meeting.

#What is a pitch deck for investors vs. a sales deck?

An investor pitch deck sells the company as an investment, so it covers market size, traction, team, and the ask. A sales deck sells the product to a buyer and focuses on their problem, outcomes, and pricing. Same format, different reader.

#What are the 5 key elements of a pitch deck?

Problem, solution, market, traction, and the ask. Team and business model matter too, but those five are what an investor scans for in the first minute.

#What is the 10/20/30 rule?

Guy Kawasaki's constraint: ten slides, twenty minutes, thirty-point minimum font. The font floor is the real lever, because it forces you to cut text down to what matters.

#What file format should I send a pitch deck in?

Send a PDF or a view-only link so the layout holds on any device, and keep an editable source (PPTX, Keynote, or Google Slides) to update numbers between meetings.
