You send the deck. Then nothing.
Every founder knows that silence. Almost nobody knows what is inside it.
Papermark does. Founders share decks as tracked links instead of attachments, so every open, every page, and every second comes back as data
24,541 decks. 1,374,380 investor views. 15.2M data points. Four findings, in order of how much they should change what you do next:
👋 We’re Marc and Iuliia from Papermark. We built it so every founder can raise faster and every deal can be tracked. Every number below came from decks shared through it
1. You get 77 seconds, not four minutes
The average view lasts 4.0 minutes. That is the number everyone quotes.
The median is 77 seconds. Meaning that half of the views are just a bit longer than 1 minute.
The gap is the finding. Views split rather than cluster:
▫️ 16% are gone inside ten seconds
▫️ Nearly a third run past three minutes
▫️ Almost nothing sits between
Investors either dismiss a deck on the cover or sit down and read it. There is no average investor, and a deck built for one is built for nobody.
Read your own numbers this way. A run of views under thirty seconds is a list problem. Views over three minutes with no reply is the opposite: they read it, and the ask failed.
2. Everyone who leaves, leaves on slide two
Eighteen points of your audience disappear between the cover and slide two. After that you lose about two per slide, until roughly half remain at the end.
The cover holds 5.1 seconds at the median. Every slide after it holds about three. Covers are not interesting. The cover is where the investor decides whether to keep going.
It is the highest-leverage slide you own, and usually the least worked on. Name, what you do, best number, before any agenda slide.
One belief the data kills: longer decks do not lose readers faster. Past the cover, a 25-page deck holds more readers at any given slide than a 16-page one. Readers pace themselves to the length they can see. What empties the room is the end approaching, rather than the page count.
3. Twelve pages is the number
46% of decks land between 9 and 16 pages. The data adds the cost of going longer, and the cost arrives early.
Completion falls 20 points from 8 pages to 16, then only seven more by 24.
Twelve-page decks win on every measure:
▫️ Most views of any exact length, 34 on average
▫️ Highest return rate, 68%
▫️ Half the readers reach the last slide
Sixteen and eighteen pages match the view count. Completion drops to 40%. The extra reads stop earlier.
Everything you cannot cut goes in an appendix, and the appendix goes behind the ask.
4. The slide investors want most is the one six in ten leave out
The most-read page is the team slide, at 5.7 seconds, 73% above a typical page. Investors spend their time on the people.
Financials are the instructive one. Above-median attention at 3.9 seconds, present in only four decks in ten.
High attention, low inclusion. Founders are cutting the slide investors most want to see.
The financial models library covers what belongs on it. The VC method for valuation covers the number they check first.
Order changes the result
▫️ Traction in the first three slides: 20% more views and the most reading time of any structure
▫️ Opening on financials: same views, less reading. They look rather than read
▫️ Opening on product screenshots: 14% less reading time, the worst opener measured
Most founders push traction to the back half. The data says it belongs up front.
Five Things to Do Before You Send
Send a link, not an attachment. So you can actually see who viewed your deck, secure it and control the access.
Treat the cover like it decides the raise. Eighteen points leave before slide two.
Open with traction. Keep the financials. 20% more views, and six in ten cut the slide investors want.
Twelve pages. The rest is appendix, behind the ask.
Chase the second open. One link per firm, so you can follow up the moment someone spends real time on you.
See This on Your Own Deck
Every number here came from decks shared through Papermark. Share your next one the same way and you will see which patterns your investors follow, while the raise is still running.
You see who opened it, which slides they read, how long they stayed, when they came back. The link always shows the current version, so you can swap the deck after sending. Ask for an email at the door, turn off downloads, add a watermark, or kill the link.

What Goes on the Twelve Pages
The data gives you the shape. These give you the contents:
▫️ 300+ pitch decks that raised, including 26 that raised $400M and 16 unicorn decks
▫️ What top VCs look for in 2026
▫️ The financial models library, for the slide six in ten skip
▫️ The investor lists, for the 44%
▫️ The McKinsey diligence method, for what happens after the yes
Methodology
The figures in this report are de-identified, anonymised and aggregated data generated from customer use of the Papermark Services and used in furtherance of Papermark’s business, as permitted by Section 3.3 (Aggregate/Anonymous Data) of the Terms of Service. No Customer Data, personal data, viewer identity or customer information is disclosed in this report, and no figure published here identifies, or permits the identification of, any individual document, viewer, company or customer. Processing of personal data is governed by the Privacy Policy.
This is why I think a pitch deck has to communicate the core idea almost instantly. If the important insight only becomes clear after several slides, the investor may never reach it. The interesting challenge isn’t fitting more information into a deck—it’s deciding what deserves to survive the first few seconds.
77 seconds is fairly brutal when you think about how many weeks can go into making the deck.
Useful reminder that the reader has absolutely no emotional attachment to how much work went into the deck.
