How many slides should a pre-seed pitch deck have?

About ten core slides, each answering one question. Y Combinator treats each topic as a set of one to three slides, and the decks DocSend analyses run to roughly 20 pages including appendix material.

How long do investors spend on a pitch deck?

DocSend data from mid-2024 put the average at 2 minutes 18 seconds per deck, so the deck has to be clear at a glance.

What should a pre-seed deck show without revenue?

Validation: design partners, pilots, signed letters of intent, waitlist conversion, usage, and what customer interviews taught you. Many Israeli pre-seed VCs expect at least a proof of concept or pilot.

What goes on the ask slide?

The round size, the instrument, usually a post-money SAFE at Israeli pre-seed, and the milestones the money reaches before the next round.

Should the deck I send be the same as the one I present?

Keep two versions. The sent deck needs enough text to stand alone; the presented deck can be lighter because you tell the story. To earn a first meeting, a one-pager often works better than sending the full deck.

The short answer: a pre-seed deck has about ten slides: what you do in one sentence, the problem, the solution, why now, the market, early validation, the business model, competition, the team and the ask. At pre-seed there is little or no revenue, so the deck has to prove two things above all: that this team understands a real problem better than anyone, and that it has early evidence the problem is worth solving. Keep it simple enough to understand in about two minutes, because that is roughly how long investors spend on it.

How investors actually read your deck

DocSend tracks how investors read the decks founders send through its platform. Its data in mid-2024 put the average time on a deck at 2 minutes 18 seconds. In its 2024 report on more than 400 pre-seed and seed startups, investors spent 30% more time on pre-seed team slides than the year before, and 19% less on the market size slide. An earlier DocSend analysis of pre-seed decks found successful decks held attention for about 4 minutes 10 seconds, against 1 minute 36 seconds for decks that failed to raise.

The practical conclusion: the deck has to work at a glance. Every slide should say one thing, and the story should still make sense to someone who reads only the titles.

The ten slides, in order

#	Slide	The question it answers	What good looks like at pre-seed
1	Title and one-liner	What do you do?	One plain sentence a non-expert understands. Sequoia asks for the company "in a single declarative sentence".
2	Problem	Whose pain, and how bad is it?	A specific customer, a specific pain, and what it costs them today.
3	Solution	How do you solve it?	What the product does for that customer. A demo or mockup beats a feature list.
4	Why now	Why could this not be built five years ago?	The change in technology, regulation or behaviour that opens the window.
5	Market	How big can this get?	A bottom-up estimate: number of customers times what they pay. Skip the giant top-down number.
6	Validation and traction	What proof do you have?	Design partners, pilots, letters of intent, waitlist, usage, first revenue. Dates and numbers.
7	Business model	How will you make money?	Who pays, how much, and how often. A first pricing hypothesis is enough.
8	Competition	Why will you win?	What customers use today, and the insight or advantage that sets you apart.
9	Team	Why is this the team?	Founders first, with the experience that makes them right for this problem. Full-time status.
10	The ask	What do you need, and what will it buy?	Round size, instrument, and the milestones it reaches before the next round.

Y Combinator's seed deck template follows almost the same order and treats each topic as a set of one to three slides. Its guidance fits pre-seed too: focus on the narrative, and keep the design intentionally simple.

The team slide carries more weight at pre-seed

With little data, investors are betting on people. Israeli pre-seed fund Fusion writes that at the earliest stages the team matters more than the technology. Fusion's 2025 survey of Israeli pre-seed investors found that over 80% expect founders, especially the CEO, to be full-time before they invest, and nearly 90% of VCs did not make solo founders part of their core strategy.

Show why this team is right for this problem: what each founder has done that is relevant, how long you have worked together, and who does what. Founders belong on the slide; a long list of advisors does not replace them. For more on what investors look for in a founding team, read choosing a co-founder.

Validation without revenue

Most pre-seed companies do not have revenue yet, and investors know it. According to VC Cafe's summary of the Fusion report, 58% of Israeli pre-seed VCs expect at least a proof of concept or pilot, and 33% expect paying customers. The validation slide is where you show what you have learned and who is already engaged: design partners using the product, pilots with named logos, signed letters of intent, conversion from a waitlist, or the number of customer interviews and what they told you.

The ask: size, instrument and milestones

State the round size, the instrument and what the money buys. Fusion's report puts typical Israeli pre-seed rounds at $1.1M to $1.75M, with a median post-money cap of about $6.8M, and 64% of VCs investing only through post-money SAFEs. Tie the money to the milestones that will make the seed round possible, such as a number of paying customers or a level of usage. Our pre-seed guide covers round sizing in depth, and the SAFE and dilution calculator shows what you will own afterwards.

The sent deck and the presented deck

Many decks are read without you in the room, sent by email or through a link. That version needs enough text to stand on its own. The version you present in a meeting can be lighter, with you supplying the story. Keep both. To earn the first meeting we usually suggest a one-pager first: a deck sent too early invites a decision before the conversation. Send the reading version when an investor asks for it or after the first meeting.

For Israeli founders pitching in English, have a native speaker proofread the deck. Small language errors pull attention away from the content.

Mistakes that make investors stop reading

A one-liner that needs a second read.If the first slide is unclear, the rest of the deck starts at a disadvantage.
Top-down market sizing only."1% of a $50B market" tells an investor nothing about your customers.
Too many words.Kevin Hale of Y Combinator argues each slide should express one idea and be understood at a glance.
An ask without milestones.A number without a plan for what it achieves invites the question of whether you need it.
Hiding the competition."No competitors" usually reads as "no market" or "no research".
Polish over substance.Content beats design. A clear deck in a simple template is enough.

Where Velo fits

The deck is the written version of your company's story, and the story only works when the company behind it is ready. Velo's venture studio works with a small group of pre-seed and seed teams every week on customers, go-to-market, the story and the round. See how the studio works.
