The last two days before a deadline are when founders do their best and worst editing. The best: tightening the story and fixing the slides investors read first. The worst: rewriting everything at midnight and introducing new mistakes. Public guides such as Y Combinator’s How to build your seed round pitch deck make the same point: clarity beats volume. Here’s a focused checklist to work through, based on 25+ years of building technology products and reviewing plans with founders.

1. Is your ask clear and specific?

Your ask slide should answer one question in a few seconds: what do you want, and what will it do? Vague asks (“raising a seed round”) make readers guess. Be direct:

  • State the amount you’re raising, or the specific help you need.
  • Say what it gets you to, such as launch, a first set of paying customers, or your next round.
  • Give a timeline, such as the number of months the money covers.

2. Does your use of funds tie to milestones?

A use-of-funds slide shows that you’ve thought about how the money turns into progress. Group spending into a few plain categories, such as product, hiring, go-to-market and operations, and connect each one to a milestone.

  1. Use three to five categories. More than that becomes hard to read.
  2. Show rough shares, such as a simple bar or pie, so the reader sees where most of it goes.
  3. Link each category to an outcome. “Hire two engineers to ship the first release” says more than “Engineering.”

If you can’t explain why a category is there, it probably shouldn’t be.

3. Can you back up every number?

Two days out is the right time to do a number check. Go slide by slide and ask where each figure came from.

  • Market size: is it built from real customers times what each one would pay, with your math shown?
  • Traction: is every metric labeled clearly and dated? Are sign-ups labeled as sign-ups, not customers?
  • Financials: do the totals on your ask, use of funds and projections match each other?

Our guide to common pitch deck mistakes covers more ways numbers go wrong, and our traction slide guide shows how to present early metrics honestly.

4. Does the story still flow?

Flip through the deck quickly, reading only the slide titles. Together they should tell the story from problem to ask. A simple order that works for many early decks:

If a title doesn’t move the story forward, rewrite it as a plain statement, like “Clinics lose hours each week on manual scheduling,” instead of a label like “Problem.” Our post on the slides investors expect explains what each slide should do.

5. Is your contact slide complete?

This one gets missed more than you’d think. The upload form on our Startups page asks only for the file, so your contact details must be in the deck itself. On the last slide, include:

  • Your name and role
  • Email address
  • Phone number
  • Company website

Check every detail for typos. A wrong email address can undo the work in every slide before it.

6. Run the file check

Before you call it done, export the deck to PDF and open the PDF, not the original file. Then check:

  • Fonts and layout look the same as in your editor.
  • Charts and small text are readable on a laptop screen.
  • The file name is clear, such as CompanyName-PitchDeck-Oct2026.pdf.
  • Hidden slides, speaker notes and old drafts aren’t included by accident.

Tomorrow’s post walks through exporting a PDF that anyone can open. Our pitch deck submission guide shows the upload steps.

What not to do in the last 48 hours

  • Don’t add new sections. If it wasn’t in the deck two days ago, it can usually wait.
  • Don’t redesign. A new template now can break layouts you’ve already fixed.
  • Don’t wait for perfect. A clear deck on time beats a perfect one that misses the deadline.
