Pitch deck — slide-by-slide guide
Pitch Deck Guide: What Each Slide Must Prove
A pitch deck isn't a summary of your company; it is a sequence of claims, and every slide exists to prove one of them well enough that an investor wants the next meeting.
Most decks fail quietly. Nobody writes back to say slide six lost them; the email just never gets answered. The usual cause isn't bad design or the wrong pitch deck template. It's slides that describe instead of prove: a problem slide that says the market is inefficient, a traction slide full of logos with no numbers, a team slide that lists job titles.
This guide walks through the standard sequence and, for each slide, names the one thing an investor needs to believe by the end of it. It draws on publicly shared decks from companies that went on to raise, and on the mistakes that get a deck closed after a quick skim.
What a pitch deck is for, and the two versions you need
The job of a deck is to get the meeting, and then to structure it. It is not meant to close a round on its own. That means you need two versions. The send deck is read alone, often quickly, so every slide must make sense without you in the room. The presenting deck can be sparser, because you are there to tell the story.
Keep it to roughly ten to fifteen slides. Sequoia's widely referenced outline is a good spine: company purpose, problem, solution, why now, market potential, competition and alternatives, business model, team, financials, and vision. You don't have to follow it slavishly, but if you drop a slide, know which question you are leaving unanswered.
Slides one to three: company, problem, solution
The opening slide should define the company in a single declarative sentence: who you serve and what changes for them. If an investor can't repeat it to a partner afterwards, it's too clever or too vague. The problem slide has to prove the pain is real, frequent and expensive for a specific customer. The strongest version uses the customer's own words, or a number from your own conversations, rather than a borrowed industry statistic.
The solution slide proves your approach removes that specific pain better than what people do today. Show the product, or a screenshot, or the workflow before and after. Resist listing features. One clear before-and-after beats ten bullet points.
Slides four to six: why now, market size, traction
Why now is the slide founders skip and investors love. It should prove something changed recently, a technology, a regulation, a behaviour, a cost curve, that makes this possible or necessary today and explains why it hasn't been built already.
Market size should be built from the bottom up: number of target customers times what each could realistically pay. Top-down claims about a vast market just signal you haven't done the work. And conservatism can mislead too: Uber's 2008 deck, later published by co-founder Garrett Camp, framed its best case as around $1 billion in annual revenue, a fraction of what the company went on to earn.
Traction proves people want it. Use the metric that matters for your model, such as revenue, paying customers, retention or pilots converted, and show it over time. Be precise and honest. A WOW Mentor teardown of early Dropbox sales describes a large enterprise deal won partly by admitting the company's biggest existing customer was far smaller, instead of inflating the numbers. Investors check.
Slides seven to ten: business model, competition, go-to-market, team
The business model slide proves you can make money on each customer: how you charge, the price, gross margin, and what it costs to acquire a customer versus what they are worth over time. Early on, a clearly stated assumption is fine, as long as it is labelled.
The competition slide proves you understand the alternatives, including spreadsheets, agencies and doing nothing, and why you win against them. Avoid the two-by-two chart where you sit alone in the top right corner; it rarely convinces anyone. Go-to-market proves you know how the first hundred customers will find you. Name channels you have tested, not every channel that exists.
The team slide proves this group is unusually suited to this problem. Relevant experience, prior results and why you care beat logos of past employers. If there is an obvious gap, say how you plan to fill it.
The ask, the financials, and mistakes that get a pitch deck skipped
Close with how much you are raising, what it buys in milestones, and roughly how long it lasts. Financials at seed stage are about the shape of the plan, not precise forecasts: a simple view of revenue, burn and runway that ties back to your model. Airbnb's founders, in co-founder Brian Chesky's post about their early rejections, were seeking $150,000 at a $1.5 million valuation, a concrete ask that made the decision easy to evaluate, even though most investors they met passed.
The recurring mistakes: too much text to read in the time an investor gives a cold deck, no clear customer, market size with no method behind it, traction without dates, a missing ask, and a deck that needs the founder in the room to make sense. Fix those before worrying about fonts.

Checklist for today
- 1.Write your one-sentence company definition and test whether a stranger can repeat it back.
- 2.For each slide, write the single claim it must prove at the top of the page before designing anything.
- 3.Rebuild your market size from the bottom up: target customers times realistic annual spend.
- 4.Put dates and precise numbers on every traction metric, and remove anything you can't back up.
- 5.Make a separate send version that reads clearly without you and ends with a specific ask.

Frequently asked questions
How many slides should a pitch deck have?
Roughly ten to fifteen. Enough to cover problem, solution, why now, market, traction, business model, competition, go-to-market, team and the ask. Detail beyond that belongs in an appendix or a data room that you share after the first meeting.
Are pitch deck templates worth using?
A template helps with order and layout, and many free ones follow the same structure as Sequoia's outline. The risk is filling slots with generic text. Decide what each slide must prove first, then use the template only to lay it out.
Should a pre-revenue startup include financial projections?
Include a simple view of how the business will make money, what you will spend, and how long the round lasts. Investors know early forecasts are guesses. What they want to see is that your assumptions are explicit and connect to your pricing and go-to-market plan.
Can I use a pitch deck to apply for a bank loan?
Usually not on its own. Banks lend against repayment ability, so they typically ask for a business plan with cash flow projections, the purpose of the loan and details of your own investment. A deck is built for equity investors who are buying a share of future growth.
