Three minutes. Eight slides. A room full of investors who've already seen 15 pitches today and have 10 more to go. This is demo day — the most compressed, high-stakes format in fundraising.
Everything that works in a normal investor deck — nuance, detail, supporting data — gets cut. What survives: one bold idea per slide, the strongest possible version of each point, and a pace that keeps the room's attention from slide 1 to your ask.
This playbook gives you the 8 slides that work in a 3-minute format, with prompts designed for maximum impact.
The Rules of Demo Day
One idea per slide. If a slide makes two points, it makes zero. The audience is processing fast — give them one thing to absorb per slide.
No reading required. If you have to read the slide out loud for it to make sense, it's too wordy. The slide should support your spoken words, not duplicate them.
Every second counts. You have roughly 20 seconds per slide. That's enough for one strong visual, one number, or one statement — not all three.
Bold over detailed. This is not the meeting where you prove every claim. This is the meeting where you earn a follow-up meeting. Be confident, be clear, be memorable.
The 8 Slides
Slide 1: The Hook
Time: 15 seconds
What it does: One sentence that makes 200 people stop checking their phones. Not your company name. Not your team. One insight, one question, or one number that creates curiosity.
Prompts to try:
"One bold sentence, centred on a dark background. Nothing else on the slide. Large text, brand colour accent. The sentence types itself out word by word."
"Hook slide with a single surprising statistic: '£4.2 billion wasted on decks nobody reads.' The number counts up from zero, large and alone. Dark background, stark, dramatic."
"Provocative question filling the entire slide: 'What if every deck was built for the person reading it?' Large serif font, centred, generous spacing. No logo, no company name."
Slide 2: The Problem
Time: 20 seconds
What it does: Makes the problem visceral and relatable. The audience should feel the pain — or recognise it from their portfolio companies.
Prompts to try:
"Three pain points, each with a cost figure. Large numbers in red, short descriptions in white. Dark background. The numbers appear one by one, staggered. Each one hits harder than the last."
"Problem slide with one powerful image and one line of text. The image shows the frustration. The text quantifies it. Split screen — image fills the left, text is bold on the right."
"Before/after contrast in two words. Left side: 'Hours.' Right side: 'Minutes.' The left is grey and heavy. The right is bright with brand colour. The two words slide in from opposite sides."
Slide 3: The Solution
Time: 20 seconds
What it does: Shows what you've built — in one visual or one sentence. Not how it works (that comes next in a follow-up meeting). Just what it does.
Prompts to try:
"Product hero shot — one clean screenshot of the product in action. No feature list, no annotations. Just the product looking great. The screenshot fades in with a subtle scale effect."
"One sentence describing the solution: 'AI builds a custom-designed deck from your website in 2 minutes.' Large, centred, bold. Below it, a small product screenshot as proof. Clean and confident."
"Split: the old way (PowerPoint template, 4 hours) vs the new way (Dev Decks, 2 minutes). Visual contrast — left is static and grey, right is dynamic and coloured. The right side animates in."
Slide 4: Traction
Time: 30 seconds (this is the slide that matters most)
What it does: Proves you're not just an idea. Numbers that show real momentum — users, revenue, growth rate, engagement. This is where investors decide whether to lean in.
Prompts to try:
"Three hero metrics, large and bold: users (12,500), MRR (£240k), growth (34% MoM). Each counter climbs from zero. Brand colour accents. Dark background. This slide should feel like a scoreboard."
"Traction dashboard — one main metric massive and centred (MRR counting to £240k), with three supporting metrics smaller below (customers, growth rate, NPS). The main metric counts first, then the supporting stats appear."
"Growth chart taking the full slide — a line rising steeply from left to right. Key milestones marked on the line: first customer, first £10k MRR, first enterprise deal. The line draws itself. At the end, today's number appears with a glow."
"Stat cards snapping into position from scattered positions around the slide — each card lands in a grid: revenue, users, retention, growth. Each counts up after landing. Fast, energetic, confident."
Slide 5: Business Model
Time: 15 seconds
What it does: Shows how you make money — in the simplest possible terms. Pricing model, who pays, average deal size. Nothing complicated.
Prompts to try:
"Business model in one visual: 'Freemium → £29/month → £49/month per seat.' Three tiers shown as an ascending staircase. Each step is labelled with the tier name and price. Clean, obvious."
"Revenue model — two numbers: average revenue per user (£35/month) and current customer count (1,200). Below: 'That's £42k MRR and growing 34% monthly.' One slide, three facts. Counters for all numbers."
"Unit economics in four cards: CAC (£45), LTV (£840), LTV:CAC (18.7x), Payback (6 weeks). Each card has the metric name and number. Clean grid, brand colours. Every number counts up."
Slide 6: Market
Time: 15 seconds
What it does: Shows the market is big enough to build a large company. TAM, SAM, or a clear framing of the opportunity size.
Prompts to try:
"Market size as concentric circles — TAM (outermost, £8B), SAM (middle, £1.2B), SOM (innermost, £180M). Each circle appears from the outside in. Our position glows at the centre. Clean, simple."
"Market opportunity in one number: '£8 billion spent on presentation tools annually.' Large, centred, counts up from zero. Below it, one line: 'And none of them build custom slides.' Stark, confident."
"Bottom-up market sizing: '50,000 companies × £350/year = £17.5M achievable in 3 years.' Three numbers building left to right, connected by multiplication signs. The final number is highlighted and bold."
Slide 7: Team
Time: 15 seconds
What it does: Shows why this team wins. Not full bios — just names, photos, and the one credential that matters most for each person.
Prompts to try:
"Team — 3 founders in a row. Circular photos, name, and one line each: 'Ex-Google, built X at scale.' 'Ex-YC founder, 2nd exit.' '10 years in enterprise sales.' Clean, fast to scan. Photos fade in one by one."
"Team slide with a twist: instead of listing credentials, show what the team built. 'Together we've: scaled to £10M ARR, built products used by 2M people, raised £15M across 3 companies.' Metrics in a row, team photo below."
"Founding team — large circular photos with names and a single killer credential each. Below the team: logos of previous companies they've worked at. Two rows: faces, then logos. Clean, credible."
Slide 8: The Ask
Time: 10 seconds
What it does: What you're raising, what it's for, and how to reach you. Clear, confident, no hedging.
Prompts to try:
"The ask: 'Raising £2M to scale to 100k users.' One line, large, centred. Below it: use of funds in 3 bullets (hiring, product, growth). Below that: founder's email. Dark background, brand accent. Confident and direct."
"Closing slide — the funding amount counts up to £2M. Below: three allocation bars (team 50%, product 30%, growth 20%) that fill to their percentages. At the bottom: 'Let's talk — ahmed@company.com' with a subtle pulse."
"Bold close: just the number '£2M' massive on a dark slide. Below it in smaller text: 'To build the future of decks.' Contact details at the bottom. Nothing else. The number counts up, holds, then the CTA fades in."
Demo Day Design Rules
Set these at the deck level before building individual slides:
"Every slide should be bold, high-contrast, one idea only. Dark backgrounds. Large text. No bullet lists. No paragraphs. This is a 3-minute pitch — every slide should hit like a headline."
"Demo day energy — fast, confident, dramatic. Every slide should feel like a poster, not a document. One focal point per slide. Brand colours used sparingly for maximum impact."
"Design this like a billboard — if someone can't understand the slide from across the room, it's too complex. Large numbers, bold statements, minimal decoration."
What to Cut
If you're over 8 slides, cut in this order:
- The "How It Works" slide — save it for the follow-up meeting
- Competitive landscape — you don't have time to position against 5 competitors
- Detailed financials — unit economics can wait for due diligence
- Product roadmap — investors want to see what you've built, not what you plan to build
- Multiple testimonials — one metric beats three quotes in a 3-minute format
Practice Tips
Time yourself. 3 minutes is shorter than you think. Practise until you finish at 2:45 — that gives you breathing room.
Don't read your slides. The slides are for the audience's eyes. Your words are for their ears. They should complement each other, not duplicate.
Pause on the traction slide. This is where investors decide. Let the numbers land. Don't rush past your strongest moment.
End with energy, not apology. "We're raising £2M" — not "We're hoping to raise around £2M if you're interested." Confidence is contagious.
