Building a deck. The long, technical, cited guide.

A pitch deck is not a document. It is an artifact passed around a partnership Slack channel by an associate at 11pm on a Sunday.

The most-cited public dataset on investor reading behavior is DocSend's Pitch Deck Interest Metrics work, which has tracked investor sessions across tens of thousands of founder decks. The headline finding has been stable across vintages: a successful investor session lasts roughly three to four minutes, and the time is spent disproportionately on team, traction/financials, and product[1]. Every design decision in this guide proceeds from that fact.

The deck has two jobs and only two. The first is to get the meeting. The second, once the meeting happens, is to be the shared reference document the partner uses to repeat your bet to the rest of the room when you are not there. That is it. It is not a business plan, a product spec, or a vision statement. It is the minimum viable shared mental model of your company.

Most founders build the wrong thing because they imagine a careful reader. There is no careful reader. There is a tired reader, a skeptical reader, and a reader who already half-passed before they opened the file. Write for those three.

The reader's mental funnel

The funnel above is not a literal sequence; investors jump around. But the gating questions are real, and they are answered in roughly that order. If any one of them gets a "no", the rest of the deck is irrelevant. Build for the gates, in order.

The canonical pitch deck has between ten and fifteen body slides. DocSend finds that decks that successfully raise are most often between 14 and 19 slides total, with a median around 19 when an appendix is included[1]. Sequoia's own template runs about ten[2]. Y Combinator's recommended structure is similarly tight at around ten to twelve slides[3]. Andreessen Horowitz publishes a sixteen-slide guide[4]. The variance is real but the band is narrow: build for roughly twelve body slides plus an appendix.

The order I use

Twelve body slides, in this sequence:

• 1. Title. Company, one-liner, round, contact.
• 2. Problem. One painful, expensive, or growing problem. Quantified.
• 3. Why now. The specific shift that makes this possible today and not five years ago.
• 4. Wedge. The narrow first product. Not the platform.
• 5. How it works. A picture of the product in use.
• 6. Traction. Numbers, or proof of insight if pre-revenue.
• 7. Market. Bottom-up TAM, never top-down.
• 8. Business model. One sentence and one chart.
• 9. Competition. Including "do nothing" and "spreadsheets".
• 10. Team. Why this team wins this race.
• 11. Ask. Amount, instrument, milestones, runway.
• 12. Vision. The platform the wedge becomes. One paragraph.

A16z's seed-stage deck guide proposes a similar shape with a slightly different ordering and gives the structural reasoning for each slide[4]. First Round's research adds an interesting twist: founders who lead with a clear problem statement raise faster than those who lead with the product[5]. Lead with the problem. Always.

Slide 1 · Title

Company name, a single descriptive line in plain English, the round ("Raising $2.5M Seed"), founder name, email, date. That is the entire payload. No tagline. No logo wall. No "Confidential" in red — decks get forwarded, and pretending otherwise reads as naive.

Slide 2 · Problem

One sentence at the top stating the problem in the customer's own language. Underneath, two or three bullets that quantify it: how many people, how much money, how often. DocSend's per-slide data consistently shows the problem slide gets only a sliver of session time[1], and that sliver decides whether the rest of the deck gets read. If your problem is generic, you have lost them by slide three.

Slide 3 · Why now

The single most underwritten slide in seed-stage decks. Sequoia calls it the most important slide in the deck because it forces the founder to articulate the non-obvious tailwind[2]. A good "why now" answers: what changed in the last 18 to 36 months that makes this company possible, valuable, or urgent? Cost curves, regulatory change, platform shifts, new model capability, new data availability.

Bad "why now" slides cite ChatGPT or COVID as if those were arguments. They are background. The argument is what specifically changed in your sub-segment.

Slide 4 · Wedge and product

The wedge is the first painful problem you solve for the first identifiable customer. It is narrow on purpose. Investors fund wedges, not platforms, because wedges are testable in 18 months and platforms are not. Bill Gurley's well-known framing is that the best businesses look small at first and only become obvious in hindsight[6]. Show the small thing. Talk about the platform on the vision slide.

The product slide is the one place a screenshot or short workflow diagram is non-negotiable. Investors want to see that the thing exists. If it does not exist yet, show the highest-fidelity mock you have and label it as a mock. Pretending a Figma is shipping product is a tell partners catch immediately.

Slide 5 · How it works

The "how it works" slide answers the question the partner cannot ask out loud: what is the customer actually doing inside this software, and what would they have done without it? A working version is a sequence — input, action, output — illustrated with real screen fragments. The wedge slide tells the partner what you sell. This slide tells them what using it feels like.

   Anchor:    Acme Co., Q1 2026 pilot, n=1,420 events

Slide 6 · Traction

Traction is the slide investors spend the most time on[1]. In DocSend's published per-slide breakdowns, the traction/financials block consistently absorbs the largest share of session time — multiples of the title slide. If you have revenue, show ARR or MRR with the monthly trajectory for the last six to twelve months. If you have users, show actives and retention curves. If you have a waitlist, show conversion to paid where possible.

   ARR ($k)
   400 ┤                                            ●
   350 ┤                                       ●

     0 ┤  ●  ●
       └──┬──┬──┬──┬──┬──┬──┬──┬──┬──┬──┬──┬──
         M1 M2 M3 M4 M5 M6 M7 M8 M9 10 11 12

   Net retention: 142% · Logo retention: 96% · CAC payback: 7.1 mo

The Mosaic effect: a single chart showing time on the x-axis and a metric going up and to the right is worth more than ten bullets. Founders consistently underrate how much investors care about the slope of the line versus the absolute number. A small absolute number with a steep slope often outperforms a large flat number[7].

Slide 7 · Market

Always bottom-up. Top-down TAM slides ("the global X market is $400B") are almost universally dismissed by professional investors[8]. The defensible bottom-up model is: number of target customers × realistic ACV × realistic penetration. Show the arithmetic. If the number is small, do not lie about it; instead, show how it grows.

TAM  = Σ (target accounts in segment_i  ×  realistic ACV_i)
SAM  = TAM × % reachable through your GTM channels
SOM  = SAM × % win rate against incumbents in 5 years

Worked example (vertical SaaS for US dental practices):

  target accounts        =   142,000  US dental practices       [ADA, 2024]
  realistic ACV          =     $4,800  ($400/mo, 1.5 seats avg)
  TAM                    =     $682M
  SAM (reachable via PLG)=     $410M  (60% of TAM, urban/suburban)
  SOM (5-year, 12% pen.) =      $49M

Slide 8 · Business model

One sentence: who pays you, how much, how often. One simple unit economics chart if you have one. If your gross margin is unusual for the category, explain why. Investors at this stage care less about precision than about whether you understand your own economics.

Slide 9 · Competition

Do not use a 2x2 with you alone in the top right. It is a meme[9]. Use a feature comparison table or a positioning map that includes "the status quo" and "spreadsheets" as competitors. The honest competitive slide says: here is what customers do today, here is why it is bad, here is why we are better, and here is what we are not yet better at.

                       │ Spreadsheets │ Incumbent A │ Incumbent B │   Us

   AI workflows        │      ✗       │     ✗       │     ✗       │   ✓

Slide 10 · Team

The team slide is the second most-read slide in the deck after financials[1]. Show the founders, their relevant prior work, and the specific reason this team wins. The unhelpful version is a row of headshots with logos underneath. The useful version answers: why this team, why now, what you have built or shipped together before.

Slide 11 · The ask

Be specific. "Raising $3M on a SAFE at $20M post" is more investable than "Raising a seed round." State the milestones the round buys: revenue, hires, product, geography. State the runway in months. DocSend data is unambiguous that decks with a clearly stated ask close faster[1].

Raising:  $3.0M  on a post-money SAFE  @ $20M post
Runway:   22 months
Buys us:
  • $1.5M ARR  (from $240k today)
  • 8 hires    (4 eng, 2 GTM, 1 design, 1 ops)
  • SOC 2 Type II
  • US-East + US-West data residency
Series A target:  Q3 2027 at $1.5M ARR, 130% NRR

Slide 12 · Vision

One paragraph. What does the world look like when you have won? This is where you are allowed to sound ambitious. The wedge slide earned you the right to put it here.

Investors read decks on a laptop in a browser tab. Design for that. One idea per slide, large type, real charts, real screenshots. The most common deck-design failure is not ugliness; it is density. Slides with more than about 50 words of body copy correlate with longer fundraise cycles in the DocSend data[1].

Color and typography are the last 10%. They matter less than founders think. A clean Helvetica deck with real numbers will out-raise a beautifully designed deck with vague claims, every time. The best decks I have seen at the seed stage looked like they were written by adults, not designed by an agency.

The deck shows the headline numbers. The model behind the deck is where partners spend most of their diligence time. At the seed stage you are not expected to ship a 60-tab DCF; you are expected to ship a credible bottom-up model that ties the GTM motion to revenue, headcount to burn, and burn to runway. Bessemer's "Good, Better, Best" framework is the cleanest public starting point[8].

The three numbers partners actually check

• Burn multiple = Net burn ÷ Net new ARR. Below 1.0 is great, below 2.0 is acceptable at seed, above 3.0 is a red flag [10].
• Magic number = Net new ARR (annualized) ÷ S&M spend in prior quarter. Above 1.0 means scaling profitably [8].
• Rule of 40 = Growth rate (%) + FCF margin (%). Used at Series B+ but increasingly tested at A [8].

Burn multiple  =  net cash burn (period)  /  net new ARR (period)
Magic number   =  4 × ΔARR (Q)             /  S&M spend (Q-1)
Rule of 40     =  YoY growth %             +  FCF margin %

• Burying the wedge. Most decks bury the actual product behind two slides of market context. Lead with the wedge by slide four.
• Top-down TAM. "The global market is $400B." No partner has ever bought this. Build bottom-up [8].
• The hockey-stick projection. Five-year revenue forecasts from a pre-revenue company. Investors discount them entirely [8].
• Logo walls of irrelevant customers. Three real design partners beats twelve "interested" logos.
• Vague asks. "Raising a seed round" instead of "$3M on a SAFE at $20M post for 18 months of runway."
• The 'we have no competition' slide. You do. Every customer has a current solution, even if it is a spreadsheet.
• Confidential watermarks. Decks get forwarded. Acting otherwise reads as inexperience.
• Founder photos without bios. The team slide must argue why this team wins, not just who they are.
• Animations and transitions. They break in browser preview and look like a 2009 keynote.
• Sending the deck cold without a sentence. The cover email is part of the deck. Treat it as slide zero.
• Gross margin handwaving. If your category is 75% gross margin and yours is 40%, address it on the model slide, not in Q&A.
• Renaming categories. Inventing "Generative Workflow Intelligence" when you mean "AI sales tool" loses the partner. Use the boring name.
• NDAs at the cold-deck stage. Signal you do not understand the market [9].
• Showing MRR without retention. Growth without retention reads as a leaky bucket. Always pair them.
• Ten advisors on the team slide. One unfair-advantage advisor is leverage; ten is decoration.

The deck is written backwards. Start with the ask. If you cannot state the ask in one sentence, the rest of the deck cannot do its job, because the deck exists to justify that ask. Once the ask is locked, write the team slide. Then the traction slide. Then everything else.

Write the body in plain text first, in a single document, with no slides. One sentence per slide. If you cannot state the slide's claim in one sentence, the slide is not yet a slide. Only after the plain-text version reads cleanly do you move to slides.

   Week 1   Week 2          Week 3            Week 4
   ──────── ────────────── ────────────────── ──────────────
   Plain    Slide v1       Operator review    Investor v1
   text     (structure)    (kill 30%)         (send cold)
   ──────── ────────────── ────────────────── ──────────────
   Lock     Add charts     Rewrite traction   Track DocSend
   ask      and screenshots and ask           opens, iterate

Iterate against real readers. Show the deck to three operators you trust before you show it to a single investor. Operators will tell you when a slide does not earn its place. Investors will tell you when you have already lost them, but by then it is too late.

Plan to write the deck three times. The first version gets the structure right. The second gets the words right. The third is the one you actually send. Founders who think they are done after version one are the same founders who wonder why the round is taking six months.

Track who opens the deck and how long they spend on each slide. DocSend, Attach, and Pitch all do this natively[1]. The data is not a vanity metric; it tells you which slides are working and which are losing the room. If investors consistently bail on slide six, slide six is broken. Rewrite slide six, not the cover email.

The weekly investor update during the raise

The follow-up is part of the deck. A clean weekly update during the raise turns warm leads into committed money and committed money into a closed round. The format is boring on purpose: highlights, lowlights, metrics, asks, what's next. Five sections. Plain text. Send it on Mondays.

Subject:  [Company]  ·  Week of MM/DD  ·  Raise update

Highlights
  • Closed Acme as design partner ($24k ACV, 12-mo pilot)
  • 2 partner meetings scheduled for next week

Lowlights
  • Lost a verbal from Fund X on geography (US-only thesis)

Metrics (since last update)
  • ARR:  $312k → $338k  (+$26k)
  • Pipeline: $1.2M qualified, weighted

Asks
  • Intros to: Fund A, Fund B (specific partner, with reason)

What's next
  • Term sheet conversations open with two funds
  • Targeting first close by [date]

The appendix is where you put everything you do not need on a cold read but every diligence call asks for. Treat it as the second deck inside the deck. Separate it with a divider slide that says "Appendix" and nothing else.

• Cohort retention curves by signup month, dollar and logo.
• Funnel conversion rates from top-of-funnel to closed-won.
• Sales motion economics: ACV by segment, sales-cycle length, win rate.
• Pricing details: tiers, discounts, expansion paths.
• Hiring plan: roles, start months, fully loaded costs.
• Cap table summary: pre-money, option pool, prior rounds.
• Risks page: top three risks, what would change your mind, mitigations.
• Customer logos and quotes: real, attributed where allowed.
• Detailed competitive map: more than fits on slide nine.
• Founder bios: long form, with citations of prior outcomes.

Every partner meeting has the same shape. The first ten minutes are your deck. The next thirty are questions. The questions are mostly the same questions, in different orders, drawn from the same partner-room playbook.

The standard fifteen

• "Why is now the right time, specifically?"
• "Who is the customer and what did they do yesterday?"
• "What is the one feature that wins the deal?"
• "What is your CAC and how do you know?"
• "What does net retention look like, dollar and logo?"
• "What does the first $10M of ARR look like, channel by channel?"
• "Who is the second hire after this round closes?"
• "What kills this company in 18 months?"
• "Why this team, beyond the resumes?"
• "What does the Series A look like — milestones, multiple?"
• "How does the incumbent respond when you reach $5M ARR?"
• "What is the bull case and what is the base case?"
• "What is the moat in two years that does not exist today?"
• "What is your gross margin path?"
• "What did the last customer who churned tell you?"

The right preparation is to write a one-paragraph answer to each of these, out loud, and rehearse them until you can deliver any one of them in under 90 seconds. Founders who do this raise materially faster than founders who do not. The deck got the meeting. The Q&A closes the round.

• Title slide includes round size, instrument, name, email, date.
• One painful, quantified problem on slide 2, in the customer's language.
• "Why now" is a specific, dated, citable shift — not background noise.
• The wedge is on slide 4, and it is genuinely narrow.
• Product slide has a real screenshot or a mock labelled as a mock.
• Traction chart shows time on x, metric on y, with retention next to it.
• TAM is bottom-up, with the arithmetic visible.
• Unit economics: gross margin, NRR, CAC payback, all stated.
• Competition slide includes "spreadsheets" or "do nothing".
• Team slide answers "why this team specifically".
• Ask slide states amount, instrument, runway, and milestones.
• Vision is one paragraph. Not a slide of bullets.
• Appendix has retention cohorts, hiring plan, and a risks page.
• File is under 8MB, named Company_Round_Date.pdf.
• Cover email is two sentences and a link, not three paragraphs.
• You have read it out loud, top to bottom, in under four minutes.
