BOM’S GUIDE TO INVESTOR PITCHDECKS

Turn what you know
into a story
investors can believe.

A strong pitchdeck makes your business understandable, your evidence inspectable and your next step worth discussing.

A clearer pitch starts here.

For founders preparing their first investor deck or improving an existing one. Explore twelve building blocks, visual slide examples and complete decks from real companies. Learn what each slide needs to establish, how to build the argument and what evidence can support it.

Follow Gauge, a fictional industrial software startup, from customer insight to funding ask. Look behind each concise slide to see the strategic choices, assumptions and next tests. Then apply the principles to your own business.

Build in the tools you already use, with your team. Start with a complete reading deck, derive the live version, then extract your elevator and one-dollar pitches.

How to build this slide

  1. 01

    Start with the capabilities this particular business needs: customer access, technical delivery and commercial execution. Match each founder to a clear responsibility.

  2. 02

    Choose one relevant, verifiable achievement per person. Explain what they actually delivered and how that experience helps with the next milestone. A famous employer’s logo alone says little.

  3. 03

    Show the most important capability still missing and when you will fill it. Distinguish full-time founders, employees and occasional advisers.

VALIDATION BEHIND THE CLAIM

Check experience against delivered work and references. Customer relationships, previous deployments and the team’s speed of learning can support founder–market fit. Credentials do not validate customer demand.

Make it visible

People + roles + one relevant achievement each. Add one honest capability gap.

The investor’s question

What has this team already done that makes the next difficult step more credible?

Inside Gauge: the strategy, evidence and next decision Read the thinking behind this slide

FICTIONAL CASE · One year into building Gauge · All research, customers, figures and results below are invented for teaching. They are not externally validated.

The strategic choice

Two full-time founders split accountability: the CEO owns customer discovery, sales and adoption; the CTO owns connectors, reliability and security. Their prior experience is useful because the first bottleneck is integrating into real quality workflows, not building a flashy demo.

The supporting case

Fictional case record: CEO previously led inspection rollouts at 12 plants; CTO has six years in machine vision. Together they have spent one year narrowing the workflow: 100 interview sessions with 68 people at 32 plants, 12 observed workflows at eight plants and four completed paid pilots. The CEO closed all three production contracts.

The next decision

Hire an implementation engineer first. Hire a commercial lead only after the founders can document a repeatable sale. A new salesperson cannot repair an unclear ICP or an unreliable deployment.

Gauge is a fictional industrial software startup. All example figures, people, product screens and plans are illustrative. Photographs are AI-generated. Use the reasoning; replace every claim with your own evidence.

Clear story> many slides
Insights> buzzwords
Evidence> assumptions
Focus> scope creep

THE THREAD THROUGH EVERY SLIDE

Let the market
strengthen your story.

A pitchdeck is a concise account of what you have learned and what you intend to prove next. Start with the customer’s reality. Separate what people say, what they do and what they pay for.

Use your own research wherever possible. Combine it with credible external sources to test its reach. When evidence is missing, show the assumption, the planned test and the decision it will inform.

Illustrative founders examining an engineering component together
Observe the work before designing the slide. AI-generated illustration, not a real customer visit.
01

Understand the problem

Recent incidents, observed workflows, baseline cost.

Does this matter enough to act?
02

Test the solution

Task completion, use in context, concrete commitments.

Will people change their behaviour?
03

Test the business

Paid pilots, signed terms, real delivery costs.

Will a buyer pay enough to make it work?
04

Test repeatability

Retention, repeated sales, repeatable deployment.

Does the result hold beyond the first few?

Each kind of evidence answers a different question. Payment does not prove retention, and a successful pilot does not prove that deployment will scale. Customer permission and confidentiality still apply when quoting or displaying evidence.

BOTTOM-UP MARKET SIZING

Build the number.
Show the assumptions.

The buying unit stays the same from market to revenue. Here it is one manufacturing site paying €24k per year. All counts in this Gauge example are fictional planning inputs.

TAM
10,000 × €24k€240m / year

1,200 Benelux + 3,800 DACH + 5,000 other European eligible sites. Validate these census assumptions.

SAM
2,000 × €24k€48m / year

5,000 in-region → 3,000 workflow-fit → 2,000 supported by connectors and service coverage.

SOM
60 × €24k€1.44m exit ARR

Three-year scenario: 3 starting sites + 7 + 20 + 30 net additions.

Collect: a dated, deduplicated account list; workflow and budget interviews; priced offers and contracts; actual funnel and onboarding data. Use registers or industry data to check the wider count.

Challenge: are sites genuinely eligible, is price sustainable, and can the team reach and serve them? At €18k–€30k per site, the same SAM spans €36m–€60m. Years two and three need more capacity and potentially another round.

Reconcile: year one is 120 named accounts → 40 qualified meetings → 14 paid pilots → 7 new customers. This is a capacity-constrained hypothesis, not a guaranteed percentage of SAM.

Professional network · Defensibility & thesis

COMPLETE PUBLIC DECK06

Make the investment logic visible.

Read Reid Hoffman’s annotations alongside the slides. Separate the investment thesis from the evidence available at that moment.

Look for: How the network’s development supports the argument about future value and advantage.

03 / THE PITCH GUIDE

One story. Four ways to tell it.

Build the complete pitchdeck first. Then derive the version you present, the elevator pitch and the one-dollar pitch. Work in your own presentation and notes tools.

Start with a story, then give it a structure.

Open with your company name and a plain-language sentence about what you do. Use the twelve building blocks to build the investment case: team credibility, customer pain, your solution and value, the opportunity, proof, economics and a route to growth. Finish with the milestones and the ask. Explain why now where it belongs: what changed in technology, behaviour or the market to make this possible or urgent?

The order can change; the questions still need answers. Keep technical depth and supporting financials in an appendix. Prepare the complete reading deck before extracting its shorter versions.

01

Send-ahead deck

Understood without you

02

Live presentation

Told by you

03

Elevator pitch

30–60 seconds

04

One-dollar pitch

One clear sentence

The sequence and timings below are our practical synthesis. “One-dollar pitch” means the shortest useful one-sentence explanation here; it is not a standard investor format or a literal word budget.

FIRST: TWO DECKS

Same facts.
Different delivery.

Keep the customer, claim, evidence and ask consistent. Adjust how much explanation the slide must carry.

Informed by Techstars on live pitching (opens in a new tab) and YC on slide design (opens in a new tab).

4-ENGINEER BUYER SCENARIO**

*Same 12 engineers / 4 sites; median of individual average weekly hours over 2 baseline weeks vs 6 pilot weeks. Human review included; setup excluded.

**Buyer scenario: 4 engineers × 6h × 46 weeks × €60. Capacity value, not cash savings. €31.6k includes subscription, pilot and internal setup.

FICTIONAL DATA · EDUCATIONAL EXAMPLE04 / 12
READER GETS THE CONTEXT

Make the evidence understandable on its own.

Across 12 engineers at four completed pilot sites, the median of individual average weekly report reconciliation hours fell from eight hours in a two-week baseline to two during a six-week pilot. The comparison includes human review; deployment effort is outside the measurement. This is an early result, not proof of the outcome at every plant.

Use a short explanatory caption, not a page of prose. A complete reading deck is still selective.

THEN: EXTRACT THE SHORTER PITCHES

Compress the story.
Keep its meaning.

Start from the approved deck. Select what the listener needs now; do not read twelve slide titles faster.

30–60 SECONDS · ELEVATOR PITCH
“Gauge helps quality engineers turn scattered inspection reports into one review queue. Today they lose hours reconciling reports by hand. In four completed pilot sites, median weekly reconciliation fell from eight hours to two across 12 engineers in a six-week pilot, including human review but excluding deployment. Three production customers pay us €6,000 in monthly recurring revenue. We’re raising €1.5 million to make deployment repeatable and validate our sales economics. Would it make sense to discuss whether this fits your investment focus?”

Fictional example. Rehearse at a natural pace; adjust to the actual slot and audience.

Problem + solutionBenefit + best proofAsk + next step
Keep customer + product + outcome.
Remove metrics and the funding ask if they obstruct understanding.
ONE SENTENCE · ONE-DOLLAR PITCH
“Gauge helps factory quality engineers review inspection reports in one place so they spend less time reconciling reports.”

Extracted from the problem, solution and value slides. This invites a follow-up; it does not try to establish the whole investment case.

A WAY OF WORKING

Build once. Derive carefully. Improve together.

One founder owns the story; a teammate challenges the evidence. Get an unfamiliar reader involved before you polish the design.

  1. 01

    Agree the investment story

    Write a short narrative before designing slides: who has the problem, what changes, why you can win, what is proven and what this round unlocks. Use the twelve blocks as a completeness check.

    Output: an agreed story and an evidence list.
  2. 02

    Make one takeaway per slide

    Turn topic labels into claims a reader can understand. Choose a visual that explains or supports each claim. Put a definition, date, source and limitation next to important numbers.

    Output: a complete, self-explanatory deck in your own presentation tool.
  3. 03

    Challenge it with a cold reader

    Send the PDF to someone who has not heard your pitch. Without narrating, ask who the customer is, why they buy, what is proven and what the funding achieves. Fix the places they misread.

    Output: a deck that works without you in the room.
  4. 04

    Derive the live version

    Duplicate the approved deck. Keep the same facts and story. Move explanations into speaker notes and technical depth into an appendix. Keep one takeaway and one useful visual per slide; retain essential evidence labels.

    Output: a presentation you can talk through naturally, with time for questions.
  5. 05

    Extract the shorter pitches

    Pull only the sentences that identify the customer, problem, product, benefit, strongest proof and next step. Turn them into a 30–60 second elevator pitch; then strip it to the customer, product and outcome for one sentence.

    Output: an elevator pitch and a one-dollar pitch, both traceable to the deck.
  6. 06

    Rehearse, listen, synchronise

    Record yourself and time a natural delivery. Ask someone to repeat the business back. Cut wording if you rush; clarify wording if they misunderstand. Keep one owner and review date for facts across all four formats.

    Output: one consistent story, maintained in four useful forms.

01

Founder & customer clarity

Can a cold reader explain the customer, pain, product and reason to change?

02

Analyst & consistency

Do claims match records? Do the funnel, delivery capacity, margins and cash plan reconcile?

03

Investment manager & founder response

What could break the investment thesis? Which changes or new evidence would reduce that risk?

A useful loop: build the full reading deck → request a prioritised review → discuss it as a team → accept, reject or test the feedback → update the deck and evidence together. After two or three substantive rounds, seek new customer evidence where rewriting no longer helps.

Keep the distinction clear: AI can question a claim; it cannot turn an assumption into market validation. Ask for slide references and missing evidence, check its arithmetic and sources, and preserve uncertainty in rewritten text.

Use your own environment: attach the downloaded file or paste a prompt into your chosen AI tool. Share only authorised material, check the tool’s data settings and remove unnecessary confidential details. This site does not receive your deck.

Shorter must still mean the same thing.

A pilot does not become a customer. A forecast does not become traction. An early result does not become a guarantee. Update the master facts, then check every version against them.

The read-back test builds on Michael Seibel’s guidance at Y Combinator (opens in a new tab).

04 / THE PITCH GUIDE

Make the evidence fit the venture.

Use the same principles at every stage. Change the proof you can honestly offer.

Pre-seed

Founder insight + a testable thesis

Direct observations, prototypes and credible design partners. Show what you learned, what is still a hypothesis and the next test.

Seed

Early adoption + reasons to repeat

Distinguish paid customers from pilots. Show usage, initial retention, willingness to pay and a focused route to market.

Series A

Repeatability + quality of growth

Explain cohorts, expansion, cost to serve and the sales motion. Connect growth to the resources and economics that sustain it.

DEEPTECH & HARDWARE

Connect technical progress to commercial proof.

Distinguish lab results from field validation. Show technology readiness, IP rights, qualification, manufacturing and the buyer’s adoption cycle. A technical milestone and a customer milestone should support one another.

BEFORE YOU SEND OR PRESENT

Read it like an investor.
Defend it like a founder.

  • A reader can explain our customer, problem and solution without me narrating.
  • Every key number has a definition, date and source; assumptions are labelled.
  • Market maths connects our first segment, price and realistic reach.
  • The ask reconciles with cash needs, runway and measurable milestones.
  • We have permission to share customer names, quotes, screenshots and data.
  • We can discuss the largest risks and what would change our minds.
