This video is a talk by Y Combinator's Managing Director Michael Seibel, specifically teaching startups preparing for the seed stage how to pitch to real investors. It covers the core message structure that builds investor trust, how to avoid mistakes, and traps you must avoid in a pitch—all in a very practical way. It repeatedly emphasizes that "clarity, brevity, and easy understanding" are the real secrets to leaving a lasting impression. Packed with actionable examples and engaging dialogue, this is essential advice for any founder!

1. Y Combinator and the Spirit of Entrepreneurship

Michael opens his presentation with the bond shared among founders and the vision of the YC (Y Combinator) program.

"If you're foolish enough to start a startup, I think you should have each other's backs."

He talks about the 'unfair advantage' YC provides to founders and the organization's pioneering spirit in creating models that didn't exist before. YC batches are also among the most aggressively scouted startup groups in the world.

"When you see another company here suddenly take off, you think 'Oh, we need to get back to work right now.' That's the kind of motivation you get."

He explains that for a company to survive over 100 years, "you must forge your own path rather than follow tradition." Most importantly,

"You don't start with all the answers. Sometimes you just need the courage and environment to believe for just one more day."

2. Startup Pitching — Why Is It So Hard?

Before getting into the main content, Michael empathizes with the fear every founder has about pitching.

"Every founder remembers the moment they were rejected by an investor, and somehow they develop something close to a desire for revenge."

With pitching being this painful, where does it go wrong? He declares that he will share only the rules most needed for startups preparing to raise before achieving product-market fit, not for larger rounds like Series A.

"Rethink the funding advice you already know. Most of it is wrong."

3. The Core Is Clarity and Brevity! "The Easiest Way to Explain Your Startup"

The real way to differentiate yourself is by speaking clearly, simply, and briefly.

"If I can't understand what your company does, I will never invest."

The most common mistake is making your own explanation overly complex or trying to package it to "look impressive."

Specifically, for example?

He summarizes the Airbnb case in exactly two sentences:

"Airbnb lets every homeowner or apartment owner rent out their place online. All payments are processed online, and they take a 15% commission on every booking."

Then he gives a truly compelling example:

"A waiter living in Washington D.C. could list his place during Obama's inauguration and earn two to three months' rent. Just take photos and post them on Airbnb. Airbnb handles the payment, finds good guests, and with that money, he pays two to three months of rent!"

This kind of specific, story-that-sticks-in-your-head example is what matters.

4. Investors vs. Customers — The Explanation Must Be Different

Many founders explain to investors the same way they do to customers—with jargon or implicit rules from their field.

"Investors are usually not your actual users. Rather than complex terms that sound impressive, you need to explain in really simple everyday language."

In other words, you need to prepare separate explanations for customers and investors, and the sentence on your website's homepage is not the same sentence you should use in a pitch!

"Be 80% accurate but 100% clear. That's much better than being 100% accurate but only 50% understood."

5. Specific Examples — Why Do They Matter?

Abstract explanations and specific examples produce completely different results.

"You can make money by renting out your place during big events." (Abstract, not memorable)

In contrast, when you embed specifics like the Obama inauguration, the waiter, and two to three months' rent, the listener can 'immediately picture it.'

6. Problem-Solution Structure, and Make It Clear on the First Slide

"If the investor doesn't understand your business by the time you move past the first slide, it's already over."

That's why he emphasizes that directly asking is also a good approach:

"So, after hearing all this, do you understand our business, or do you need more examples?"

7. The Ideal Team Slide

The team slide shouldn't be too long. Briefly highlight 'what capabilities each team member has,' and it's especially good to weave in personal experience with the problem.

"If you faced the very problem you were thirsty to solve before starting the company, and that's why you started it, then I can see you as an expert."

Clearly divide roles like CEO and CTO, and don't leave out specifics about 'what made them impressive.'

"For example, in this batch there was a founder who built Mars rover software, but they didn't mention it at all during their pitch! You absolutely must mention something that impressive."

8. Traction — Proving Growth

The traction slide needs to impactfully explain "how fast and what you've accomplished."

• Only use graphs when they trend upward
• Small achievements are still achievements, but "no change in 2 years" is actually a negative!
• Always clearly state the timeframe

"If you got an iOS app to 100 testers in one month, even if not many people are using it yet, that's impactful. But if it took 2 years, there's no impact."

And:

"Fake achievements (advisors, meaningless surveys, etc.) are actually a negative." "If you truly have no achievements, it's better to remove the slide. This isn't about pretending—investors will look at what they can actually trust before investing!"

9. Unique Insights — You Need a 'Secret'!

This slide only has power when you have a 'real insight that others don't know' about the business.

"Before Airbnb, booking/sharing platforms didn't handle payments. But without payment trust, both hosts and guests feel anxious and the market doesn't function. When a third party manages payments, everything changes completely."

Key points to note:

• If more than 50% of people would agree, it's not 'unique'
• Don't be vague—use numbers and case studies

10. Market Size — The 'Calculation Logic' Is More Valuable Than the Number

"How big the market is matters less than how you calculated that number."

• You must explain the user count, pricing, and why you set prices that way yourself
• Always include comparisons with similar products (competitors)
• Citing newspaper articles or external reports doesn't impress anyone

"Explaining it with math makes you look like an expert and makes investors trust you far more."

11. The Ask — Actually Ask for It!

Surprisingly, many founders don't 'actually' ask for money at the end.

"After 70% of pitches end, the words 'please invest' never actually come out." "There's a third type of investor. They feel so uncomfortable saying 'no' that they just write a check on the spot! That's up to 10% of investors. To target their psychology, you absolutely must ask for investment directly."

What to emphasize on the Ask slide:

• Clearly state 'how much, where, and by when' for your goals
• Show who has already invested (social proof) and how much
• Specifically say "with this money, we will achieve this result within 18-24 months"
• "We'll hire someone" doesn't carry much weight. Prioritize revenue and user growth

12. Overall Pitch Structure and Ordering

For the overall flow of a pitch, he emphasizes the following:

• 'What you do' must come first
• After that, lead with whatever is your strongest selling point among team/traction/unique insights!
• Expose the good stuff 'early and often'
• "Remember just three things. Start with 'what we do,' end with 'how much money we're asking for,' and in the middle, pull forward whatever has the biggest impact!"

"People don't listen well for 30 minutes. Especially on Zoom these days where attention spans are even shorter, you need to give them a noteworthy point every 2 minutes!"

13. Common Mistakes in Pitching

• Running a pitch like a 'book report assignment'
• Not having a conversation with the investor, only delivering one-sided information
• The more you get the investor to talk, the higher the investment probability

"Really good sales is about getting the customer (investor) to talk more. They want to convince themselves."

Be sensitive to real-time reactions!

• Carefully observe the investor's expressions, attention level, and real-time reactions

  "The fancier the slides, the lower the success rate. 'Simplicity' matters more than design. Instead of one beautiful image, focus on your voice and message!"

14. Live Example — YC's Own Pitch Demo

At the end, Michael demonstrates a Y Combinator pitch 'live.' (Accurate and concise, applying everything explained above!)

• 'What do you do?': "We're a startup accelerator that has invested in the world's best tech startups for 18 years."
• Example/Experience: "I personally experienced YC with Twitch (Justin TV). At the end of the 3-month batch, I raised money right at Demo Day."
• Traction: "Among YC-funded companies, 75 have annual revenue over $100 million."
• Team: "YC partners have real-world experience in founding, investing, hiring, firing—everything—and are also YC alumni."
• Unique Insights: "Almost anyone can apply without a warm introduction, and batchmates provide overwhelming mutual help. Demo Day works like an auction format, driving higher valuations."
• Market: "There are over 40 VC-backed tech company IPOs per year."
• Ask: (Clearly stated)

15. Q&A — Practical Questions & Real-World Founder Advice

The Q&A features practical concerns along with Michael's characteristically candid real-world explanations.

• For existing funding/advice, 'do no harm' comes first

  "Even if I think I know the answer, giving the wrong answer is more harmful. It's better to let the founder talk to customers themselves."

• For experienced industry veterans

  "Startups are incredibly painful, and founders are a bit mentally... different. If a comfortable big company and good job sound appealing, I'd recommend going that route. Startups are right for people who find those 'good conditions' absolutely unbearable."

• Deck vs. free-form pitching?

  "If you're experienced, you can have a conversation without specific slides, but for beginners, a 'deck' is a huge help. The trick is to judge from experience which approach conveys your message better!"

• Need to introduce competitors?

  "If you repeatedly get asked about competitors, put it in the 'appendix.' But generally, investors are more interested in 'whether there's really a big player in the market' than in 'who your competitors are.'"

• Tech/open-source startups, early traction and revenue metrics

  "Don't imitate what giant companies are doing now. Benchmark what strategies they used when they first reached $10 million in revenue!"

• For an inexperienced 23-year-old founder

  "Arm yourself with weapons (competitive advantages) before heading to the battlefield (market). Even if it takes time, focus less on 'whether others are already doing it' and more on 'how can I equip myself with favorable weapons.'"

• When to worry about legal/regulatory compliance?

  "In the early stages, it's not too late to address it only when actual customers raise it as a problem. Just handle the basic legal structure, and specific regulations/compliance can come later!"

• How do you evaluate team capability?

  "More valuable than a thousand competitor analyses or surveys is the concrete proof of having 'done an unimaginably fast and large amount of work' in the past month."

Wrap-Up

Michael Seibel's advice puts the emphasis on 'clarity' instead of 'complexity,' 'brevity,' and 'pitching through conversation.' If you're a founder, re-examine your pitch deck and sales approach right now.

"Boldly discard the flashiness, and explain in a way that truly 'sticks in their ears'—a message the audience will actually remember and relate to. Never forget that investing is an 'interaction' where you get the audience to convince themselves!"

Keywords at a glance:

• Brevity, clarity, specific examples, separating investor/customer language, emotional appeal (Ask), founder persistence, minimizing mistakes

With just this summary, your investment pitch could be completely transformed!
