How to Build the Best Y Combinator Pitch Deck

A strong Y Combinator pitch deck does one thing well: it tells a clear, believable story about your company’s potential. Investors read hundreds of pitch decks each month. They’re looking for clarity, traction, and a solid business model, not design tricks or filler text.

In this guide, we’ll walk you through how to build your own pitch deck that matches Y Combinator standards. You’ll learn what slides to include, how to write each one, what key metrics investors care about, and how to make your story visually compelling and easy to follow.

What Makes a Y Combinator Pitch Deck Different

YC’s approach focuses on clarity over complexity. A YC pitch deck is usually short, around 10 to 12 slides, and structured for fast reading. Every slide supports one idea and leads naturally to the next.

Investors judge most decks within the first minute, so your presentation design must help them process your story quickly.

Three signals every strong deck should show

1. Clear problem and solution – Does your solution slide prove how your product or service fixes a real pain point?
2. Proof of demand – Do you show measurable traction through user metrics, user engagement, or growth rate data?
3. Fit for the market – Does your business model make sense given your market opportunity and stage?

When these elements align, you’ll capture investor attention and stand out in the crowded seed stage landscape.

The Core Slides in a Winning YC Pitch Deck

Every winning pitch deck follows a logical structure. Below, I’ll break down each slide with specific guidance on what to include and how to write it.

1. Title Slide

Start with your company name and a simple one-liner that explains what you do. This is your first impression. Keep it concise and easy to understand. Describe your startup in two sentences plus one specific example to make it impossible to misunderstand.

Example:

“Acme Health - simple telehealth for remote workers.”

How to craft it:

• Keep headline ≤ 10 words.
• Add your website or tagline in small text.
• Avoid filler like “Revolutionizing” or “Next-gen.”

2. Problem Slide: Nail the P.A.I.N.

Your problem slide is one of the most crucial steps in a successful pitch. It sets up your entire investor pitch deck. If you miss the mark here, it’s hard to recover. Venture capitalists see vague claims like "the system is broken" every day. What cuts through the noise is a sharp, specific articulation of real pain points, backed by data points, not buzzwords.

Here’s how to make your slide compelling using the P.A.I.N. framework:

• Problem: What exact pain does your product or service solve?
• Audience: Who experiences this pain- and how often?
• Impact: What’s the cost in time, money, or lost opportunity?
• Non-obvious insight: What have you learned that others in the market missed?

Weak Example:

“Scheduling is inefficient and outdated.”

Strong YC Pitch Deck Example:

“Clinic admins spend 12 hours per week manually submitting insurance claims- the top cause of delayed reimbursements.”

Founder Insight:

“In user interviews, 7 out of 10 clinic managers said billing software caused more problems than it solved. That insight shaped our entire business plan.”

Expert Tip: Avoid jargon. Keep your language simple and your story believable. The goal isn’t to impress but to effectively communicate pain that your target market deeply feels.

3. Solution Slide

Explain what your service solves and how it works. Highlight the main product or service feature that delivers value.

Include:

• One headline benefit (≤ 12 words).
• Two or three concise bullet points describing outcomes.
• One image or short demo screenshot.

Example structure:

• Headline: “Automated payroll for small teams.”
• Bullets:
  • “Reduces processing from 4 hours to 10 minutes.”
  • “Integrates with QuickBooks and Gusto.”
  • “Accurate tax filings every cycle.”

4. The Market Opportunity

Every seed round pitch deck must prove there’s room to grow. Estimate your total addressable market (TAM) using a bottom-up calculation: start from your real target market and multiply by your pricing. Calculate market size using transparent math to show how you arrived at your figures.

Keep the math visible but simple. Investors need to see that you’ve done the thinking, not that you’ve built a model for show.

5. Business Model

Describe how you make money. Investors want a solid business model that’s easy to understand.

Include:

• Primary revenue streams (subscription, commission, transaction fees).
• Pricing example.
• Short note on scalability.

Example:

“$49/month subscription + 1 % transaction fee on payments processed.”

Extra insight: Add a 3-row table mapping pricing tiers or expected margins. Keep it visual, no dense paragraphs.

6. Traction and Key Metrics

This is where your deck builds credibility. Investors want real proof. Highlight user acquisition, retention, and revenue growth in a clean chart. Present traction with timeframes to demonstrate momentum rather than just metrics.

How to craft it:

• Show trends visually (one clean chart).
• Bold your key metrics above the graph.
• Avoid vanity stats. Focus on growth and engagement.

7. Competitive Landscape

Every market has competition. Show how you’re different through your unique value proposition. You can use a simple table or a two-column layout:

Expert Tip: Limit to 3–4 competitors. Highlight differentiation, not superiority. Investors want to see your unique angle, not claims of being “better.” Emphasize what makes your solution distinct and valuable.

8. Team Slide

Investors don’t fund ideas; they fund people. Your team slide should introduce key team members and highlight the team’s expertise that supports execution. Showcase your team's specific, impressive accomplishments rather than their titles or roles.

Structure:

• Name – Role – One-line proof of skill.
• Keep to 3 people max and add rest in the appendix.

Example:

• Jane Rivera, CEO — ex-Google PM, 8 years in SaaS.
• Michael Lee, CTO — led payments infra at Stripe.

Add: Short note on complementary skills or an innovative approach that gives you an edge.

9. Financial Projections and Seed Round Ask

If you’re raising a seed round, outline what you plan to achieve with the funds. Use a short table: Add a clear ask for investment with specific milestones for the next 18-24 months.

Also include:

• 12-month financial projections (revenue and burn).
• Expected runway after the seed round.
• Growth goals (users or MRR).

10. Closing Slide

Reinforce your mission in one sentence. End with a short thank-you and contact details. Keep it simple and one slide that’s easy to remember.

Include:

• Tagline or mission line.
• Contact info.
• Clear CTA: “Raising $750k for 18 months' runway to reach 10k users.”

Presentation Design and Format

Good design helps investors focus. You don’t need an agency-level slide deck. You need a clean, readable layout. Here’s how you can build decks that hold the audience’s attention:

• Use white backgrounds and dark text for easy reading.
• Stick to one idea per slide.
• Use visual aids sparingly, charts or screenshots, not clip art.
• Keep fonts large and lines short.
• Limit paragraphs. Use bullet points whenever possible.

Popular pitch deck formats:

• Slide deck (PDF) — for email.
• Interactive deck (Notion/Figma) — for review calls.
• Demo Day presentation — optimized for a 5-minute talk, larger fonts.

Most founders spend too much time on visuals and not enough on structure. The goal is to make your deck extremely easy to read, not to win design awards.

Common Mistakes to Avoid

Even the best ideas can get lost in poorly constructed decks. Here are five common pitfalls that weaken your investor pitch:

• Wall of text: Long, dense paragraphs bury key points. Use bullet points and white space to make your ideas scannable.
• Unclear business model: If an investor can’t explain how you make money in one sentence, your model is too complex. Simplify until it’s obvious.
• Missing market math: Don’t skip your market size. Always include a bottom-up calculation to prove demand and opportunity.
• Generic team slide: A resume isn’t enough. Show relevant experience, complementary skills, and what makes your team credible to solve this problem.
• Over-designed slides: Flashy animations or heavy graphics distract from your message. Clean design and visual hierarchy help maintain audience attention.

Fix these, and your deck will instantly feel sharper.

Expert-Level Pitch Deck Tips

Seed vs. Series A Pitch Decks

Your pitch deck’s structure should evolve with your fundraising stage. At the seed stage, focus on demonstrating product-market fit, team credibility, and early traction. Investors want to know: is the problem real, is your solution working, and are you the team to scale it?

For Series A, expectations are higher. You'll need to show unit economics, user retention trends, and in-depth financial projections. Series A decks lean more analytical, but they should still tell a clear, cohesive story.

Using Appendix Slides Strategically

Don’t overload your main deck. Save detailed charts, product roadmaps, and market expansion plans for the appendix. This keeps your core slides tight and narrative-driven, while still giving investors access to deeper data if they’re interested.

Follow-Up Strategy

After sending your deck, use tools like DocSend or Pitch to track views. Give the investor 48 hours, then follow up with a short, respectful message: “Just checking in. Any feedback on our deck?” One thoughtful nudge is enough.

Design for Clarity

Great decks don’t win design awards. They communicate fast. Stick to one idea per slide, use large, readable fonts, and make sure your slides look good on mobile. A simple layout signals confidence.
