Y Combinator has a standard, proven pitch deck template, the exact format they recommend for early-stage startups. It’s boring, it’s simple, and it works.

I’m Arjun Mahadevan, CEO and founder of doola.com, a Y Combinator-backed startup that has raised over $13 million. Today, I’ll walk you through how to build a pitch that actually gets funded, using the same framework that helped us raise our first million dollars.

Why Most Pitch Decks Fail

Before we dive into that, let’s discuss why most founders spend weeks on decks that never complete a single round.

The problem is not your idea. That’s not your team. That means you approach your pitch like a design project, not a sales document.

Investors view hundreds of decks every month. They don’t want artistic slides or clever animations. They want clarity, traction, and proof that you can deliver.

That’s exactly what the YC pitch deck template delivers.

YC 10-Slide Pitch Deck Framework

Let’s build your deck, slide by slide.

Slide 1: Title Slide

Rule: Keep it very simple. Your logo and a one-line description.

Example: At doola, we use: “Business in a Box for Global Founders.”

Your actions: Write your company name and a 3-5 word tagline that explains what you do. Don’t think too much about this. If someone can’t understand what you do in five seconds, simplify it.

Slide 2: The problem

Outlook: Investors fund suffering, not possibility. Be specific about the problem you are solving.

Error: Vague statements like “Starting a business is hard” are not enough.

Example: “International founders lost weeks and thousands of dollars trying to set up a US entity. The process was broken, offline, and required a fax machine.”

Your actions: Write down the specific problems your customers are experiencing right now. Use the native language they would use, not industry jargon.

Slide 3: The Solution

Outlook: What do you do to relieve the pain?

Example: “We built a platform that programmatically forms an LLC, obtains an EIN, and opens a bank account. The user clicks a button; we handle the paperwork.”

Your actions: Describe your product in one sentence. There are no buzzwords like “revolutionary AI-powered platform.” Just explain what it does.

Slide 4: Traction (Most Important Slide)

Outlook: This is where you win or lose the encounter. Proof beats promises every time.

Error: Saying “We plan to launch next quarter…”

Example: “Launched 2 weeks ago. GMV $5k. 10 paying customers. Growing 20% ​​week over week.”

Your actions: Enter your best numbers in large font. If you don’t have revenue yet, use waitlist signups, letters of intent, or user engagement metrics. But you need real numbers.

Slide 5: Traction Part 2 (Impact Slide)

The question: What impact did you feel? Show additional metrics or customer validation.

Example: Include customer testimonials that demonstrate your value proposition. One powerful quote from a user can actually be worth more than a dozen beauty metrics.

Your actions: Display your key metrics or showcase customer offers that prove that people really want what you’re building.

Slide 6: The Secret Sauce (Your Competitive Advantage)

The question: What makes you different? How does it work?

Example: At doola, we explain our Flywheel AI Co-Founders and why competitors can’t easily copy our approach.

Your actions: Identify what is unique about your solution. This could be proprietary technology, a unique business model, or a structural advantage in how you deliver value.

Slide 7: Business Model

Rule: How do you make money? Keep it straightforward.

Example: “We charge a subscription fee of $297/month or $2,997/year.”

Your actions: Indicate the economic unit. Price times volume. Investors want to see a clear path from customers to revenue.

Before You Continue: Are You Ready to Accept Investment?

This is what most founders miss: You can have the perfect pitch deck, but if you haven’t set up your business structure properly, investors won’t pay for it.

US investors will not transfer $1 million to your personal checking account. Before investors take a serious look at your financials, they ask one question: “Do you own a US company?”

If you haven’t joined yet, these are the steps you need to take before sending your deck to anyone. You’ll need a C-Corp or LLC, a Tax ID Number (EIN), and a business bank account ready to accept investments.

This is why we built doola, to handle formation paperwork so founders can focus on building their business instead of dealing with red tape.

Slide 8: Market (TAM Slide)

Rule: Investors want to see a market that is big and has room for big returns.

Example: “The business formation market in the US is $X billion. The international market is 5x larger.”

Your actions: Perform bottom-up analysis if you can. Show how many potential customers there are and how much they are worth. Top-down market research is fine, but specific calculations are better.

Slide 9: Team

Rule: Why are you and your team the right people to build this?

Example: Show your founding team specific credentials that relate to this issue. Previous startup experience, domain expertise, or technical skills are important.

Your actions: Include your photo, name, and most importantly—why your background qualifies you to execute on this opportunity.

Slide 10: Questions

Rule: Be clear about what you are raising and what you will do with it.

Example: “Raised $2M seed round to reach $1M ARR in 12 months.”

Your actions: State the amount you have raised and the specific milestones you will achieve with the capital. Investors need to know what success looks like.

What Makes a Pitch Deck Really Work

Now that you have the structure, let’s talk about what differentiates funded decks from ignored decks.

Clarity over creativity. Your deck is not an art project. A simple slide with a clear message always beats a complicated design.

Traction on promises. One slide of real metrics is worth ten slides of projected growth charts.

Specificity over generality. “We reduced customer acquisition costs by 40%” beats “We made marketing better.”

Evidence for claims. Show don’t tell. Customer testimonials, usage data, and revenue figures prove your point better than adjectives.

Common Pitch Deck Mistakes to Avoid

Mistake #1: Too many slides. If you can’t tell your story in 10-12 slides, you don’t understand your business well enough.

Mistake #2: No obvious problem. If investors don’t feel the pain you’re solving, they won’t understand why anyone would pay for your solution.

Mistake #3: Burying the attraction. Your growth metrics cannot be missed. If you are growing, explain.

Mistake #4: Unclear questions. Don’t end your plan without telling investors exactly how much funding you’ve raised and what you plan to accomplish with it.

Mistake #5: No proof of execution. Investors bet on the team that executes. Show what you have achieved with limited resources.

After Your Deck: What Really Gets You Funded

A pitch deck sitting on your hard drive gives you exactly $0.

The deck is important, but it’s just the beginning. You need to get in front of investors, deliver a compelling pitch, and close the deal.

The best pitch decks are conversation starters, not comprehensive business plans. Your goal is to get meetings, tell a clear story, and prove you’re worth following up with.

Use this framework, keep it simple, and focus on the metrics that matter. That’s how you build a pitch deck that actually gets funded.
