YC Application Word Limits — What to Write in Each Field

Short answer

The YC application has strict character and word limits on every field. Most founders treat these limits as ceilings. The best founders treat them as targets — every character counts, and blank space is a missed opportunity to be specific. This page covers every field, its exact limit, and what to put in it.

The Full YC Application Field-by-Field Breakdown

COMPANY NAME

Limit: Short text field What to write: Your legal or operating company name. No taglines, no descriptors. Just the name.

COMPANY URL

Limit: URL field What to write: Your primary domain. If you have no website yet, set up a simple one-page landing page before submitting. A missing URL signals that you haven't launched anything. Even a basic page with a waitlist form shows motion.

DESCRIBE YOUR COMPANY IN 50 CHARACTERS OR LESS

Limit: 50 characters What to write: What you do + who you do it for. This is the hardest field. You have roughly 8-10 words.

Examples that work:

  • "Payroll software for Nigerian SMBs" (34 characters)
  • "Stripe for Southeast Asian marketplaces" (39 characters)
  • "AI tutor for Indian JEE students" (32 characters)

Examples that don't work:

  • "Revolutionizing the future of enterprise" (40 characters but says nothing)
  • "AI platform for businesses" (26 characters but too vague)

The test: could someone read this and immediately know what you build and who uses it? If yes, it works.

WHAT IS YOUR COMPANY GOING TO MAKE?

Limit: ~150 words What to write: Your product in concrete terms. Name the user, the action they take, and the measurable outcome they get.

Use this structure:

We build [product type] for [specific user]. [User] uses it to [specific action], which results in [measurable outcome].

Keep it to 3-4 sentences. Do not pad it with market context or vision statements. That comes later. This field is purely about the product.

IN TWO SENTENCES, TELL US THE MOST IMPRESSIVE THING ABOUT EACH FOUNDER

Limit: 2 sentences per founder What to write: The one thing about each founder that makes a YC partner think "this person can pull this off."

Common mistakes:

  • Listing degrees without outcomes ("MBA from IIM Ahmedabad")
  • Vague role descriptions ("5 years in product management")
  • Generic accomplishments ("led a team of 20 engineers")

What works:

  • Specific outcomes with numbers ("grew a SaaS product from ₹0 to ₹1.2Cr ARR in 14 months")
  • Domain proof ("ran operations at a 200-pharmacist hospital chain for 4 years")
  • Relevant builds ("shipped 3 consumer apps, one with 80,000 downloads")

Two sentences means two sentences. Do not write a paragraph and call it two sentences.

HOW LONG HAVE THE FOUNDERS KNOWN EACH OTHER AND HOW DID YOU MEET?

Limit: Short answer (~50 words) What to write: Be literal and specific. Month and year you met. Context in which you met. How long you have worked together.

"We met in August 2019 at a product management internship at Flipkart. We worked together daily for 8 months before both leaving to build this in 2023. We have known each other 5 years and co-built two side projects before this one."

This answer signals: long relationship, collaborative history, intentional cofounder choice. That is what YC wants to see.

WHY DID YOU PICK THIS IDEA TO WORK ON?

Limit: ~150 words What to write: Your personal origin story with this problem. Not why the market is big. Why you.

The strongest answers follow this arc: 1. I encountered this problem directly (or watched someone I know struggle with it) 2. I investigated it further and found it was systemic, not just my experience 3. Existing solutions failed in this specific way 4. That is why I decided to build this

One paragraph. No jargon. Specific details. If you have numbers from your research, include one.

WHAT DO YOU UNDERSTAND ABOUT YOUR BUSINESS THAT OTHER COMPANIES IN IT JUST DON'T GET?

Limit: ~150 words What to write: Your genuine insight — the non-obvious thing you know that explains why your approach will work where others have failed.

This is the field most founders misuse. They write about the market opportunity instead of a real insight.

A real insight sounds like: "Every pharmacy software company builds for the software-literate pharmacist. But 70% of independent pharmacy owners in tier 2 India have never used a computer for business. They use WhatsApp exclusively. We built entirely on WhatsApp — no app install, no login, no interface. That is why our activation rate is 94% vs the industry average of ~30%."

Notice it names the mistake competitors make, the specific user reality that explains the mistake, and your approach that addresses it. That is the shape of a real insight.

HOW DO YOU KNOW PEOPLE WANT THIS?

Limit: ~150 words What to write: Evidence only. Numbers only. No logic.

What to include if you have it:

  • Number of user interviews conducted
  • Specific things users told you (quote one if powerful)
  • Number of paying customers and revenue
  • Waitlist size and conversion rate
  • Pre-orders or letters of intent

What not to write:

  • Market size data
  • Survey statistics from reports
  • Logical arguments about why people should want this

If you have weak traction: be honest and compensate with interview depth. "We have no paying customers yet. We interviewed 80 pharmacy owners over 6 weeks across Pune and Nashik. Every single one told us the same thing: they lose money to expiry and they don't know how much until it's too late. 12 of them asked us to notify them when we launch."

That is fundable at pre-traction stage.

WHAT IS YOUR DISTRIBUTION STRATEGY?

Limit: ~100 words What to write: How you get your first 100 customers — not your first million. Be channel-specific.

"We will acquire our first 100 customers through direct outreach to pharmacy owner WhatsApp groups, of which we have already identified 47 active ones in Maharashtra with 200-800 members each. We have tested this channel and converted 8 paying customers from 3 groups so far."

Short. Specific. Proven if possible.

IF YOU HAD A MILLION DOLLARS, WHAT WOULD YOU DO WITH IT?

Limit: ~100 words What to write: Specific allocations. Not "hire great people and grow fast."

"60% on engineering — hire 2 backend engineers to build the supplier integration layer that is currently our biggest product gap. 25% on sales — hire one field sales rep in Maharashtra to run our WhatsApp outreach channel at scale. 15% on operations — move to a dedicated office and cover first 6 months of cloud infrastructure."

This answer proves you understand your constraints and have thought about prioritization.

The Fields Most Founders Ignore (But Shouldn't)

Equity breakdown: State it clearly. 50/50 splits are fine. Unequal splits are fine. Unexplained imbalances raise flags. If one founder has 80%, explain why briefly.

Previous companies: Be honest. YC does not penalize failure. They do penalize dishonesty. If you built something that failed, say what you learned. That is more credible than hiding it.

Other accelerators: If you are in another accelerator or have applied, disclose it. YC finds out. Non-disclosure is a trust killer.

The One-Line Summary

Write every answer as if a smart, skeptical person with 8 minutes is reading it. They are not looking to be impressed — they are looking for a reason to keep reading. Specific numbers, specific users, specific outcomes. Everything else is noise.

FAQ

Frequently asked questions

What is the word limit for the YC application overall?
YC does not publish a single total word count, but most key fields are capped between 50 and 150 words each. The company description field is 50 characters (not words). The product description, insight, and validation fields are roughly 150 words each. The distribution and funding fields are roughly 100 words each. Treat every limit as a target, not a ceiling — blank space signals you don't have enough to say.
What happens if I go over the character limit on the YC application?
The YC application form will typically not let you submit if you exceed hard character limits — it either truncates your answer or blocks submission. For fields with softer word guidance, going significantly over signals poor editing and self-awareness. The ability to be concise and specific is itself a signal YC is evaluating. If your answer needs 400 words, the problem is usually that you haven't thought clearly enough about what the most important thing to say actually is.
Should I use bullet points or paragraphs in the YC application?
Use the format that communicates most clearly for that specific field. The "how far along are you" field often reads better as 3-4 bullet points with specific metrics. The "why did you pick this idea" field reads better as a short paragraph with a personal narrative. Never use bullet points as a way to avoid writing a coherent sentence — bullets that say "passionate team, large market, strong traction" communicate nothing.
Is there a YC application PDF I can download to prepare offline?
YC does not officially publish a downloadable PDF of the application. However, the questions are largely consistent batch to batch and are widely documented across founder communities. You can prepare your answers in a Google Doc using the known field structure before entering them into the live application portal. This is recommended — writing in a doc gives you version history and the ability to get external feedback before submitting.
How many times do most YC founders rewrite their application before submitting?
Based on public founder accounts, most successful YC applicants go through 3-5 complete rewrites of their key fields before submitting. The most common improvement between drafts is replacing vague claims with specific numbers, and replacing market-size arguments with user evidence. A useful heuristic: if you read your answer and it could apply to any startup in your category, it needs another rewrite.
Does YC look at LinkedIn profiles or additional materials beyond the application?
YC's primary evaluation is the application form and the video essay. They do not formally review LinkedIn profiles or attached documents unless you include a link and they choose to follow it. Do not rely on external materials to carry your application — assume the form and video are the complete picture. If you have a demo, a live product, or a metrics dashboard worth seeing, link to it within the relevant field and make clear in one sentence why it is worth clicking.
What is the hardest field on the YC application for most founders?
Based on consistent feedback from YC partners and rejected founders, the insight field — "what do you understand about your business that other companies in it just don't get?" — is where most applications fall short. The majority of founders write a market observation or a feature description instead of a genuine non-obvious insight. A real insight names a mistake that competitors systematically make, explains the specific user reality that causes that mistake, and describes how your approach addresses it differently.
Can I submit the YC application in a language other than English?
No. YC conducts all interviews and program activities in English and expects applications to be submitted in English. For founders whose first language is not English, this means writing your application carefully and having a native or fluent English speaker review it before submission — not for grammar polish, but to confirm that every answer reads clearly and that nothing has been lost in translation. The goal is precise, direct communication. Simple, correct English outperforms complex, error-prone English every time.
Is it better to apply to YC early in the application window or close to the deadline?
It makes no difference. YC reviews all applications after the deadline closes, not on a rolling basis. Submitting on day one and submitting on the last day carry identical weight. Use the full application window if you need it. A stronger application submitted close to the deadline will outperform a weaker one submitted early. The only reason to submit early is personal peace of mind — it confers no advantage in the review process.
What should I do if my startup's metrics declined before I apply to YC?
Be honest about it and explain it. A decline in metrics that is unexplained is a red flag. A decline that is clearly explained — seasonal factors, a deliberate pivot, a customer segment you walked away from — is far less damaging. Partners understand that startup trajectories are rarely linear. What they are evaluating is whether you understand what happened, whether you have a clear plan to address it, and whether the underlying business fundamentals are still sound.
Should I include financial projections in the YC application?
No. YC is not looking for financial projections in the application. They know early-stage projections are largely fictional. What they want instead is your current metrics stated precisely, your growth rate over the last 2-3 months, and a clear understanding of how you acquire customers and at what cost. If you feel compelled to include forward-looking numbers, frame them as targets with a clear basis: "At our current growth rate of 18% MoM, we project $30K MRR by the time batch starts" — not a 5-year hockey stick.
How do I handle the YC application if my startup has already raised outside funding?
Disclose it clearly. State the round size, the investors, and the valuation cap if it was a SAFE or convertible note. YC invests through their standard SAFE and the terms account for prior investment. Having raised money is generally a positive signal — it means other investors believed in you. What partners want to understand is the current cap table, how much runway you have, and whether there are any structural complications that would complicate YC's standard investment terms.
