Teaser or full deck: what to send first.
Two emails sit in your drafts. One goes cold to a seed fund that has never heard of you. The other answers a partner who took a warm intro from your first angel and wrote back: "Thanks, can you send the deck?" You have one deck, built to present on a stage, and half of it is charts that only work while you talk over them.
Should both get the same deck? That is the teaser deck vs pitch deck question, and investors disagree about it in public. The partner asked for the deck, so she gets the full deck, written to be read without you. The cold fund asked for nothing, so it gets a short email and a five-page teaser that tells the whole story and holds back the detail. The slides you present on a call are a third version, and you never send them.
Below are the reasons, a rule for each moment of a raise and a teaser page list you can build tonight.
What is a teaser deck, and what does it leave out?
A teaser deck is a short version of your pitch deck, written to be read alone by someone who has not met you. Visible, a company that sells fundraising software, calls it a send-away or email deck, and its teaser pitch deck template has five slides: title, problem, solution, market and team (Visible, 2022). Slidebean, which sells pitch deck software, says a teaser should make sense without you presenting it and take a minute or two to read (Slidebean, 2023).
It is not a trailer that hides the plot. A reader who finishes it should know what you do, for whom, what proof you have, who you are and what you are raising. It leaves out detail, for three reasons.
- Curiosity. Leave questions worth a meeting. The financial model, the unit economics and the go-to-market plan invite a verdict before you have talked.
- Confidentiality. Named customers, pricing, pipeline and the roadmap stay out. Write it as if it will be forwarded, because you cannot stop that.
- A reason to meet. The last page is the ask and the next step, not an appendix.
Should you send a deck before the first meeting?
The advice lands in three places, and each has a point.
- Not before you meet. In a 2015 Entrepreneur column, Alex Iskold, then managing director of Techstars in New York, argued that a deck lets an investor decide without meeting you, sits in an inbox with no urgency and, sent widely, reaches your competitors. He suggested a two-paragraph email instead: your traction, how you differ, why you. MIT's Orbit knowledge base says the ideal is an executive summary first and the deck shortly before an in-person pitch, but admits that investors usually want the deck before they meet you.
- The deck first. Alexander Jarvis, an angel investor, wants a deck before any pitch: it shows him quickly whether a company fits what he invests in, and he reads faster than founders talk, so the call goes on the hard questions. Jason Lemkin of SaaStr, asked whether VCs like short teaser decks, answers: "Send the full deck." A light deck, in his view, rarely stands out, so the deck has to make the case alone.
- A short one first. Visible's send-away deck goes out ahead of a meeting, and Slidebean keeps the full deck for investors who are serious.
The camps are closer than they look. Iskold and MIT fear a deck that gets you judged before you can make your case, and Iskold one that travels where you did not send it. Jarvis and Lemkin fear the opposite: meetings a deck would have screened out, and a deck too thin to earn one. The teaser Lemkin dismisses is two or three slides. A five-page teaser that tells the whole story briefly and holds back the sensitive detail meets most of both worries. And when an investor asks for the deck, only Iskold would hold it back.
Teaser deck vs pitch deck: which one, when?
Decide by what the investor asked for and how well they know you.
| Situation | What to send |
|---|---|
| A cold email to someone who has never heard of you | A short email and the teaserYou have not earned the meeting yet, and it may be forwarded. |
| A warm intro, before the investor replies | Three lines on what you do and the teaser, both easy to forwardThe introducer passes on whatever you give them. |
| The investor asked for the deck | The full deck, written to be read aloneA teaser in reply looks like holding back. |
| After a first call that went well | The full deck and answers to their questions, the same dayPartners who were not on the call will read it next. |
| Due diligence | A data room with the model, the cap table and key contracts, and the deck as a PDF if they want one on fileThe deck has done its job. |
Two exceptions beat the table: an investor who says in public what they want gets exactly that, and anyone who asks for a PDF gets a PDF.
Should you send the deck you present?
No. The difference between a pitch deck you send and a presentation is the narrator. On a call you explain the chart; in an inbox the slide is alone. Jarvis draws the same line: decks read without the founder carry more words, and decks the founder presents are graphical, with fewer words.
A deck that will be read alone needs four things a stage deck can skip:
- Headlines that make the point. Jarvis asks for a takeaway on every slide, and a full-sentence headline is the simplest way to give one.
- A line under every chart that says what to look at.
- Words for anything you would explain out loud, such as the diagram you talk through on stage.
- Dates on numbers. A sent deck is read weeks later. "40 warehouses live, October 2026" survives that; "40 warehouses" does not.
PresentedTractionA rising chart, and you say the rest out loud.
SentRevenue grew 3.4 times in 12 months, across 40 warehouses.The headline makes the point, so the chart only has to prove it.
When you present, keep every number identical to the version they read. Jarvis keeps the sent deck open during a pitch and notices when the two disagree.
How long should each deck be?
Shorter than most founders make them. The reading data below comes from two companies that sell deck sharing, DocSend and Papermark. DocSend's data showed investors spending 24% less time on decks in 2022 than in 2021: just under three minutes on average, and 2 minutes 13 seconds on decks that failed to raise (TechCrunch, 2022). Papermark measured 24,541 decks and 358,672 investor views from 2024 to 2026. The average view lasted 4 minutes, but 16% ended inside ten seconds, and fewer than half of investors reached the last slide. Going from 8 pages to 16 cost 20 points of completion, while 12-page decks still took half their readers to the end (Papermark, 2026).
The two cover different years and customers, so read them as direction, not law. The direction is the same: many reads end early, and each extra page loses readers before your ask.
So keep the teaser to five pages, a read of a minute or two. For the full deck, MIT's page suggests 12 to 15 slides, and Papermark's numbers argue for the low end: cut it to what the story needs. Anything else goes in an appendix after the ask, which is where Papermark's report puts it too.
Which pages go in a teaser?
Five, in the order they sit in your full deck, each with a headline that makes its point. The examples come from Aurora Robotics, a seed-stage company building warehouse robots, and brackets mark what you fill in.
- Cover. Your name, what you do in one sentence and the round: "Robots that pick every order."
- Traction. Your best proof, with its date under it: "Revenue grew 3.4 times in 12 months, across 40 warehouses."
- Market. Who has the problem and how many of them there are, counted up from customers like yours: "Every warehouse is short of pickers. [Number] of them look like our first 40."
- Team. Two or three people, and one line on why them.
- The ask. How much, what it reaches and the next step: "$4M to reach 100 warehouses. Can we take 30 minutes to walk you through the plan?"
Aurora's product and contact pages stay in the full deck: the cover already says what the robots do, and the ask carries the next step. Your full deck keeps whatever else the teaser leaves out, such as the business model, competition and the use of funds. Starting from nothing? Build the full deck from an investor pitch template and cut the teaser last.
Cut it, never write it fresh. Copy the full deck, delete pages and shorten the rest, so every teaser headline appears word for word in the full deck, with the same numbers and dates. Keep a one-line map in your notes, such as "Teaser 4 = Full 5, Team", and change both decks on the same day. Sent as links, both show the new numbers to everyone who opens them next. Sent as files, last month's numbers stay in every inbox.
Who should get the full deck?
Anyone who asks. Beyond that, the teaser tells you a fair amount, if it went out as a link.
Aurora sent its teaser last week to four funds, on a link that asks for an email code, so each reader shows up with a verified email; an open link would show the same reads as anonymous readers, counted by device. In Decktrace, the reading report shows who opened it, how long they were active on each page and where they stopped, and readers see a short notice about what is measured.
Sarah Chen at Northline Ventures and Emma Fischer at Brightwater Capital read all five pages. Clara Holm at Fieldstone Partners stopped at page 3, and Ravi Mehta at Lumen Seed left at page 2 after 21 seconds. On Monday at 09:00 Aurora sent Sarah and Emma the full deck with one line: "Here is the full deck, with the plan and the numbers behind the teaser. Would 30 minutes next week work?"
Reading to the end is a fair signal, not a verdict: it says the teaser held them, not that they will invest. Clara may have run out of time, and 21 seconds may mean Aurora is outside what Lumen Seed invests in, which is worth knowing too. Send them a short note with one new fact, not the full deck unasked; what to do after you send a pitch deck covers the timing and the words.
The full deck keeps reporting: on Monday afternoon David Park, also at Northline, joined as a new reader on its link. When traction changes mid-raise, publish a new version of each deck and the same links show it on the next visit. That is how founders keep one link through a round.
Your teaser checklist
- If they asked for the deck, send the full deck. If nobody asked, send a short email and the teaser.
- Cut the teaser from the full deck: same headlines, numbers and dates.
- Five pages: cover, traction, market, team and the ask.
- Write every headline as a sentence that makes its point.
- Leave out the model, the cap table, named customers and anything you would mind a competitor reading.
- Read it on your phone in under two minutes before anyone else does.
- Send the full deck to whoever asks or finishes the teaser, and a short note to the rest.
- Present from a version with fewer words, and never send that one.
