How to Fill Out Investor and Accelerator Applications

A strong investor application or accelerator application answers each question directly, in plain words, with specific numbers and a clear story of who you are, what you've built and what proof you have. Reviewers often skim many forms in a sitting, so lead with facts, follow every instruction, disclose weaknesses, and keep a reusable answer bank so each new form takes hours, not days.

Definition: An investor application is a structured online form, used by accelerators such as Y Combinator and Techstars and by some venture funds, that collects standard information about a startup's team, product, traction, market and fundraise in place of, or before, a pitch meeting.

A form feels like paperwork. To the person reading it, it's often the whole first meeting.

This guide is about filling in the form well. If you're still deciding whether to apply to an accelerator at all, our guide to startup accelerators: deal terms, benefits and when to apply covers that decision, and our sibling guide on who to pitch first weighs accelerators against angels and VCs.

What investor and accelerator applications usually ask

Forms change every cycle, so check the live form before you write anything. But across YC, Techstars, a16z speedrun and the intake forms many pre-seed funds now run, the same question families come up again and again.

Question family	Typical wording	What it's testing
Company	Describe what your company does in one sentence	Can you explain it plainly?
Team	Who are the founders, how did you meet, who builds what?	Commitment, skills, history together
Progress	How far along are you? What's built?	What exists today, not plans
Traction	Users, revenue, growth, pilots	Evidence that someone wants it
Insight	Why this, why now, why you?	Founder-market fit and original thinking
Market and competition	Who else does this? What do you understand that they don't?	Realism and differentiation
Business model	How do or will you make money?	Basic commercial logic
Fundraise	Money raised so far, current round, cap table	Fit with their check and stage
Video	A short founder or demo video	How you come across, and whether you follow directions

Many funds also ask for a deck alongside the form, so it helps to have one ready that follows the 12 slides investors expect. Fund intake forms tend to lean harder on the fundraise rows. 2048 Ventures, for example, describes a pre-seed fast-track form in its September 2025 post, with fit criteria that include having raised under $2M and targeting a round of $500K to $1.5M. An accelerator form leans harder on team and progress. For how deal terms differ between programs, see our comparison of pre-seed accelerators by check size and equity.

What reviewers look for in an investor application

The clearest public explanation comes from YC. In a 2023 Startup School talk on applying, YC Group Partner Dalton Caldwell describes the questions he asks himself while reading: who the founders are and how they came together, what they're building, what exists today, whether there's evidence anyone wants it, whether the founders are serious, and what stands out.

Then he tries to tell himself a short story about the company. If he can, the application worked. If the answers are vague, he can't, and the application usually stops there.

We think that test generalizes well beyond YC. A reviewer should finish your form able to say, in two sentences, who you are, what you've built and why it might work.

Several other signals show up across official guidance:

Clarity over polish. Paul Graham's "How to Apply" page for YC treats marketing language as noise and favors matter-of-fact descriptions, including comparisons to things the reader already knows.
Following directions. Caldwell describes instruction-following as one way YC judges how detail-oriented founders are, especially on the video.
Honesty. In the same talk, he describes misrepresenting revenue or traction (for example, blurring monthly and annual revenue) as disqualifying, and notes that extraordinary claims need extraordinary evidence. Graham's page encourages founders to disclose the flaws in an idea rather than hide them.
Team and story. Techstars managing directors, in a May 2024 Techstars post, put team dynamics first and look for founders uniquely qualified to solve the problem.
Technical talent. Caldwell's talk adds that teams with at least one founder who could be hired into a technical role at a top YC company have roughly five times better odds of an interview. If that's the gap, our guide on how to find a co-founder may matter more than any rewrite.

How to write answers a reviewer can read in a minute

DocSend's research on pitch decks, summarized by Dropbox in April 2025, found investors spend less than three minutes reviewing a deck. We know of no equivalent public figure for application forms, but it's safe to plan for a quick read. These habits help, in our view.

Answer the question in the first sentence. Then support it. If the question asks for revenue, the first words are a number.
Put a period on every metric. "$18K MRR in September" beats "$18K in revenue," which could mean anything.
Name the customer. "Independent pharmacies with one to three locations" is easier to picture than "healthcare SMBs."
Use a comparison if one fits. An honest "X for Y" can save a paragraph. Skip it if the comparison oversells.
Cut adjectives. "Revolutionary," "seamless" and "AI-powered platform" add length and remove meaning.
Disclose the obvious risk. Naming it, with what you're doing about it, reads as self-awareness.
Stop when you've answered. Caldwell's guidance is that more words aren't better.

Build a reusable answer bank, step by step

Most founders apply to several programs and funds in one raise. YC's FAQ notes that you have to fill out a new application every time you apply, even if you reapply. Rewriting from scratch each time wastes hours and introduces inconsistencies, which careful reviewers notice.

An answer bank is a single document with your best, current answers to the questions that recur. Here's one way to build it.

Collect the questions. Open five or six forms you plan to submit and paste every question into one list. Group them into the families above.
Write three lengths for the core answers. A one-liner, about 50 words, and about 150 words for the company description, the team story, traction and why now. Forms impose very different limits.
Keep a facts sheet. Founding date, legal entity, location, team bios, money raised and from whom, current round, and every metric with an as-of date. Answers pull from it, so numbers stay consistent.
Date-stamp and version. Mark each answer with the month it was last true. Stale traction is one of the easiest mistakes to make when you copy and paste.
Tailor the last 20 percent. Keep the facts fixed and adjust emphasis: team and progress for an accelerator, round size and investor fit for a fund.
Log what you sent. Record which version went to which program and when, ideally in the same tracker you use for your raise. Our guide on how to track your fundraise covers the setup.

Filling the same fields into a dozen forms is still tedious. 1752 Fundraising includes a Chrome extension that fills in investor and accelerator applications, so more of your time goes to editing than retyping. Either way, read every field before you submit; autofill is a starting point, not a final draft.

A copyable answer bank outline:

FACTS SHEET (as of: month, year)
Company name | Legal entity | HQ | Founded
Founders: name, role, background (50 words each)
Product status: what's live, since when
Metrics: revenue (period), users, growth (period), retention
Raised to date: amount, instrument, investors
Current round: size, instrument, committed so far

CORE ANSWERS (one-liner / 50 words / 150 words)
What we do
Who the customer is and the problem
Why now
Why us (founder-market fit)
Traction and proof
Competition and our edge
Business model
Biggest risk and our plan
What we'd do with the money

If AI helps you draft parts of the bank, the guardrails in our guide on using AI for startup fundraising apply: verify every number and keep the voice your own.

The founder video and demo video

Videos are where many applications quietly lose points. Graham's "How to Apply" page reports that YC is statistically much more likely to interview applicants who submit a video. Caldwell's talk stresses following the written instructions for it.

Techstars managing directors, in their 2024 post, suggest a personal team video over a produced one and make the case that a rough, real product demo beats a polished marketing piece. a16z speedrun's FAQ describes inviting promising applicants to submit a short video pitch or book a 15-minute interview.

A few habits we'd consider:

Read the instructions twice. Length, who appears, what to cover.
Everyone on camera, talking. Each founder says who they are and what they do on the team.
Start with what the company does. One sentence, then the evidence.
Show the product working, if there's a demo slot. Screen recording is fine.
Do one or two takes, not twenty. Over-rehearsed tends to read as stiff.

A worked example: rewriting a weak traction answer

Here's an illustrative before and after for "What traction do you have?"

Before (weak): "We've seen incredible early demand from pharmacies across the region, with strong engagement and growing revenue. Customers love the product and we're getting great feedback. We're confident we're on track to dominate this market."

After (stronger): "$18K MRR in September, up from $6K in June. 14 paying independent pharmacies, all on monthly contracts, none churned. 9 came through referrals from existing customers. Average pharmacy saves about 6 staff hours a week on refill calls, measured in our product logs."

The second answer is about the same length and far more useful. MRR tripled in three months, which works out to roughly 44 percent compound monthly growth. A reviewer now knows the customer, the revenue, the growth, retention so far, a channel and the value delivered.

The answer bank pays off in time too. If one application takes about 3 hours from scratch, ten take about 30. Spending 6 hours building the bank and about 45 minutes tailoring each of ten forms comes to about 13.5 hours. These numbers are illustrative, but the shape tends to hold.

"Applications are a lottery, so just mass-apply"

There's something to this. Acceptance rates at top programs are low, reviewers are human, and good companies get rejected. Caldwell's talk itself encourages founders to apply rather than overthink it, and noted that most founders in the then-recent YC batches were not first-time applicants.

But mass-applying with weak answers doesn't improve the odds much. The forms are short precisely so that quality shows. What does compound, in our view, is reapplying with visible progress: YC's FAQ notes that about half of a typical batch applied more than once, and that progress since the last application is a strong signal. Apply widely if you like. Just send your best answers each time.

Where investors disagree

Programs want different depth. YC's guidance favors short, plain answers, and its FAQ notes that 40 percent of funded companies in a batch are just an idea on average. Techstars' January 2024 application guide, written by an investment associate, lists a dozen areas reviewers consider, including financial projections, go-to-market and a product roadmap.

Both are reasonable for their models. Our read: match the depth to the program. Keep the core answers short everywhere, and keep longer material (projections, roadmap, market sizing) in your bank for forms that ask for it.

Common mistakes on investor and accelerator applications

Leaving fields blank or thin, especially founder bios. Caldwell flags this as a sign of low effort.
Inconsistent numbers across forms, or between the form and the deck.
Monthly and annual figures blurred together. Label every period.
Claiming no competition. Techstars' managing directors call this out; explain how you differ instead.
Ignoring the video instructions.
Paying "insiders" to get you in. Caldwell warns that people who promise access to YC in exchange for equity or money can't deliver it, and the program is built to fund strangers who apply online.

1752vc's Accelerate admits companies on a rolling basis rather than in fixed cohorts, so its application can go into your bank alongside the batch-based programs; the $100K investment comes with founder-led sales training and access to 850+ investors.

Where we land

Our approach: build the answer bank once, keep a dated facts sheet, write every answer so a stranger could retell your story, and tailor the last 20 percent for each program.

There's no perfect application. There is a clear one, and clear tends to be enough to get you to the conversation.

The bottom line

The form is the first meeting. Treat it like one.

Specific answers get remembered.

Vague ones get skimmed.

Key takeaways

Most investor and accelerator applications ask about the same families of questions: company, team, progress, traction, insight, market, model, fundraise and video.
Reviewers tend to look for a clear story, specific numbers with periods, honesty about risks and evidence that founders followed directions.
A reusable answer bank with a dated facts sheet and answers at three lengths can cut repeat applications to a fraction of the time.
Founder and demo videos tend to reward authenticity and instruction-following over production polish.
Reapplying with visible progress is common at YC, and its FAQ describes progress since the last application as a strong signal.

Frequently asked questions

What questions are on a startup accelerator application?

Most accelerator applications ask what your company does, who the founders are and how they met, what you have built, what traction you have, why now, who the competitors are, how you make money, how much you have raised, and for a short founder video. Exact questions change each cycle, so it helps to check the live form before drafting.

How long should my answers be on a YC application?

YC's own guidance favors clear and concise answers, and Group Partner Dalton Caldwell has noted that longer answers are not better. In practice, answer the question in the first sentence and support it with a few specific facts. Many strong answers run only a few sentences, as long as they include concrete numbers and periods.

Can I reuse the same answers for different investor applications?

Yes, and many founders keep an answer bank for exactly this. Keep the facts identical across forms, with dated metrics, and tailor emphasis for each program: team and progress for accelerators, round size and fit for funds. Read every field before submitting, since a pasted answer can miss the question a specific form asks.

Should I reapply to an accelerator after being rejected?

Often, yes. YC's FAQ notes that about half of the companies in a typical batch applied more than once, and that progress since the last application is a strong signal. If you were interviewed and received feedback, showing how you addressed it can help. Programs differ, so check each one's reapplication rules.

Is it worth paying a consultant to get into Y Combinator?

We would be cautious. YC Group Partner Dalton Caldwell has warned that people who claim they can get founders into YC in exchange for equity or money cannot deliver, and that YC's process is designed to fund strangers who apply through its website. Feedback from founders who have been through a program is usually a better use of effort.
