A pitch deck holds the 11 slides investors expect: a cover, the problem, your solution, the market, the product, traction, the business model, competition, the team, financials, and the ask. Each slide answers one question an investor is already asking, and together they earn you the next meeting, not the check.

I have built decks for my own raises and torn apart plenty from other founders. Most of them fail the same way: they include the right slides, but each one proves nothing. A title with no one-liner. A market slide that claims "1% of a $50B market." This post is the slide-by-slide version, what each of the 11 has to prove, the one number or sentence that carries it, and the move that sinks it. If you want the plain definition and how many slides total, the companion piece, what is a pitch deck, covers that ground; here we go deep.

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

A pitch deck is a set of about 11 slides, each answering one question an investor has before they ask it. Most guides stop at naming the slides. The useful part is knowing what each one has to prove and the single detail that carries it, so here is the whole spine in one table.

Reorder it or drop a slide if your story calls for it. What you cannot do is keep a slide that proves nothing, because every slide an investor sits through without learning anything is a reason to stop reading.

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

A slide earns its place by proving one thing, with one detail, in a way a skimming investor can't miss. Here is what each of the 11 has to do, and the most common way founders waste it.

Cover. It proves you can name what you do before anyone has to ask. Company name, logo, and one line in the "X for Y" shape that survives being screenshotted and forwarded to a partner. Founders blow this with a mood-board tagline like "Reimagining how teams work," which tells an investor nothing about what you actually sell.

Problem. Here you prove someone is in real, expensive pain right now. The number that carries it is a cost: the hours wasted, the dollars leaked, or the share of customers who churn because of it. The classic miss is a problem nobody pays to fix, dressed up as "the market is fragmented and inefficient."

Solution. This slide proves your product removes the specific pain you just described, and ideally why that is possible now. Lead with the insight in one sentence, the thing you understand that incumbents don't, before any list of features. Founders rush straight to a wall of capabilities here, which reads as a product no one has yet decided they need.

Market. It proves the company can get big enough to matter to a fund that needs outsized returns. Build the number from the bottom up: how many customers exist times what each pays, not "we only need 1% of a $50 billion market." That top-down percentage math is the single fastest way to lose a seasoned investor, because every founder with nothing real reaches for it.

Product. Proves the thing exists and a human can use it. One or two screenshots of the core action, the moment the value lands, beat a feature museum or a roadmap of everything you will ship by 2030. The mistake is showing twelve half-built things instead of the one that already works.

Traction. This is the slide that proves it is working, and after the team it is the one investors scan first. Show the slope: revenue or active users over time, with the real figures on the axis. "Up 300%" off a base of ten users is not traction; naming the actual numbers, even when they are small, reads as confidence rather than spin.

Business model. It proves money comes in, repeatably. Price times who pays, plus one unit economic if you have it: gross margin, payback period, or an LTV-to-CAC ratio that is more than a guess. "We'll monetize later" tells an investor you have not tested whether anyone values the thing enough to pay for it.

Competition. Proves you understand the field and hold an edge you can keep. Map the real alternatives honestly, including the status quo of doing nothing, then name the one wedge you can defend. Two ways founders sink this: claiming "we have no competitors," which reads as naive, and drawing a 2x2 rigged so you sit alone in the top-right corner.

Team. Why you, and why now, for this specific problem. The detail that carries it is founder-market fit, the unfair experience, relationship, or insight that makes you the people most likely to win. The investor Itamar Novick has said that a deck covering market, moat, financials, and roadmap but missing the founder slide loses him almost immediately, and he is far from unusual on that.

Financials. Proves you have thought past the raise. A three-year projection is fine, but put the assumptions on the slide: the few drivers that turn into the revenue line, so the number reads as an argument instead of a hockey stick. Spreadsheet fantasy that doesn't reconcile with the business model you showed two slides earlier gets caught in the first diligence call.

The ask. It proves the meeting has a purpose. State the amount, the milestone it buys, and the runway, something like "$2M to reach $1M ARR over 18 months," with a rough use of funds. A deck that never names the ask, or asks for money with no milestone attached, leaves the investor with nothing to say yes to.

#What do investors actually look for?

Investors look for two things before anything else: a team that can build this, and proof it is already working. Most decks get read in well under a minute on that first pass, so the deck is really screening for reasons to say no, and your job is to remove them fast.

Behind the eleven slides, the questions are blunt. Can this be huge? Are you the team to do it? Is there any evidence at all that it is happening? Novick's point about the missing founder slide lands because at the early stage there is little else to underwrite besides the people and whatever traction exists. A widely shared piece of founder advice puts the clarity bar a different way: write the deck so a smart ten-year-old who cares far less about your company than you do can still follow it. If a partner can't repeat your one-liner after a single read, the deck has not done its job, however clean the design.

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

There is no single correct order, and the famous templates agree more than they disagree. Sequoia, Y Combinator, and Guy Kawasaki all want the same handful of questions answered; they differ mainly in emphasis and slide count.

Sequoia's classic template runs company purpose, problem, solution, why now, market size, competition, product, business model, team, then financials. The slide people forget from it is "why now," the shift in technology, regulation, or behavior that makes this the right moment to build. Y Combinator pushes the opposite of polish: lead with one legible sentence saying what you do, keep the deck near ten slides, one idea per slide, with text you can read from the back of a room. Guy Kawasaki's 10/20/30 rule is the blunt instrument, ten slides, twenty minutes, thirty-point font, a rule he wrote after sitting through too many bloated pitches as an investor. Pick one of these, adapt it to your story, and remember the order is a starting grid rather than a law; what matters is that each slide proves its point. To see how funded companies actually sequenced theirs, my roundup of pitch deck examples breaks down real decks slide by slide.

#What should you avoid in a pitch deck?

The fastest way to lose a deck is to make the reader work. Investors skim for reasons to pass, and clutter, vagueness, and missing numbers hand them those reasons for free. A few specific things to cut before you send:

• Too many slides. A 25-slide deck signals you can't tell what matters. Cap it near 12 and push the rest to an appendix after the ask.
• Vanity metrics with no baseline. "300% growth" off ten users invites the exact follow-up you were hoping to avoid. Show the absolute numbers and let them stand.
• Walls of text. One idea per slide, written as a headline a reader gets in a second, beats a paragraph nobody finishes.
• A missing or vague ask. No amount, no milestone, no reason to meet. Name both.
• Hiding the risks. Diligence surfaces them anyway, and naming the gap yourself reads as a founder who has already thought it through.

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

The thinking is yours: the story, the numbers, and the reason each slide proves its one point. The build, the part where you fight slide alignment and brand colors at midnight, is the part you can now hand to an agent.

That is where heydecks fits. heydecks is the AI slide creator that AI agents call over REST or MCP. From a prompt, markdown, or a URL it returns a live deck link, a PDF, and a native, editable PowerPoint, every export locked to your brand by the Brand Kernel. It does not invent your traction or your market: you bring the numbers and the narrative, and it assembles the eleven slides on your brand.

#Frequently asked questions

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

Problem, solution, market, traction, and the ask. If a slide doesn't feed one of those five, question whether it belongs in the main deck at all. Team and business model matter plenty too, but those five are what an investor scans for in the first minute, so make each one unmissable.

#What is the 10/20/30 rule for a pitch deck?

It is Guy Kawasaki's constraint: ten slides, twenty minutes, thirty-point font. The font size is the real lever, because a 30-point minimum forces you to cut the text down to what fits, which is usually the only thing worth saying. Treat it as a ceiling, not a target to hit exactly.

#What are the 3 C's of pitching?

Clarity, conviction, and credibility. Clarity is the one-line "X for Y" and one idea per slide; conviction is committing to a real claim instead of hedging every sentence; credibility is the traction, team, and honest competition slide that back the claim up. Decks that land all three are the ones that earn the next meeting.

#Can ChatGPT or an AI agent build a pitch deck?

Yes for the build, no for the thinking. An agent like heydecks turns your prompt, markdown, or a URL into all eleven slides with a live link, a PDF, and an editable PowerPoint on your brand. What it can't do is decide your strategy or invent traction you don't have. You bring the numbers and the story; the agent builds the slides.
