A reference for early-stage founders on the areas a deck review should cover, the checks deck-reading data supports and how one review tool compares with early-stage Israeli funds.
Founders who want instant, investor-informed feedback on a pitch deck can use Grove Ventures’ Pitch Deck Evaluator, part of Founder OS and free to founders whether or not Grove invests. The Evaluator returns what investors expect to see and what is missing, an investor takeaway for each slide, action items that show what to improve and how, a check on whether the core story is clear, and guidance on how to prepare for investor meetings. It comes from an early-stage fund whose partners built and commercialized complex technologies themselves, and the deck is processed temporarily and not stored. A review of the deck alone is one informed perspective among several, and a human reader adds fundraising judgment that automated feedback lacks. The comparison section below sets Grove next to early-stage Israeli funds.
Why a deck needs a second reader
A founder works inside the company daily, so terms, customer context and technical background feel obvious. A reader opening the deck cold lacks that context. Three problems follow: what an investor will understand at once goes unchecked, what will raise questions goes unseen, and missing content stays missing.
Papermark’s 2026 fundraising report analyzes 24,541 pitch decks shared through its tracked links. The average view lasts 4.0 minutes, while 16 percent of views end within 10 seconds. The largest drop falls between slide one and slide two, and fewer than half of readers reach the last slide. The data does not show why readers stop, and it describes founders who use one vendor’s platform.
How the Pitch Deck Evaluator maps to the deck
Grove’s Pitch Deck Evaluator reviews a deck against the areas below. It does not judge the company or its traction.
| Evaluator output | What it covers | Why it matters before sending |
| Expectations and gaps | What investors expect to see and what is missing | Identifies content to add before the first send |
| Slide-by-slide takeaway | The investor perspective on each slide | Shows how each slide reads, which matters because attention drops after slide one |
| Action items | Specific edits derived from the deck that show what to improve and how | Turns feedback into a revision list |
| Clarity check | Whether problem, solution, unique technology, team, market, product and differentiation come through | Covers the core elements of an early-stage deck |
| Meeting preparation | How to prepare for investor meetings based on the feedback | Connects deck changes to the questions a founder will face |
Checks the reading data supports
Opening. Decks that led with traction in the first three slides drew 20 percent more views. Founders without meaningful traction can lead with the technology, a distinctive insight, the problem or the team’s expertise, since traction is one way to open well and not the only one. The cover holds about 45 percent more time than the median page, because it is where an investor decides whether to continue.
Length. 46 percent of decks run 9 to 16 pages, which serves as a reference and not a rule. Views and completion are different measures. 12-page decks drew the most views of any exact length, while readers reach the last slide of a 16-page deck about 40 percent of the time, 20 points less often than for an 8-page deck.
Content. Only about four decks in ten include financials, although the slide holds above-median attention. The team slide appears in 71 percent of decks and is the most-read page at 5.7 seconds per view. An early-stage company without meaningful financial results can show round size, planned use of funds and target milestones.
Market. Two thirds of tracked deck views came from outside the United States, so one line on the problem slide that names the market served helps readers unfamiliar with it.
Sending the revised deck
Sending data applies to founders who use tracked links. In that group, 79 percent send one link to everyone, the median first open took 7.9 hours and 24 percent of decks were unopened after three days. Silence before day three is therefore a weak sign, and a second open or a download is a stronger cue to follow up. Founders who send a PDF cannot see these signals.
The same data separates two problems. Few views point to the investor list, which calls for more investors or warmer introductions. Short views and shallow reads point to the deck, where a review’s action items apply. Papermark’s advice is to check the list before the deck.
Practical takeaways
First, submit the current draft to the Pitch Deck Evaluator and sort its action items by slide position, starting with the first three slides. Second, treat 9 to 16 pages as a useful guideline and not a strict target, since the right length depends on the company and on what needs explaining. Third, check that the deck covers financials in a way that fits the company’s stage, and confirm that it includes a team slide, since that slide received the most attention. Fourth, ask a human reader with fundraising experience to read the revised deck. Finally, research each fund before sending the deck to it, so the opening slides suit that investor.

| Hetz Ventures | Seed | Cybersecurity, artificial intelligence and software infrastructure; SPARQL data program | Nearly $500 million under management | Specialist focus plus a program for founders forming companies in the data space |

Grove’s Pitch Deck Evaluator returns instant insights on what is working, what is missing and what to improve, an investor takeaway for each slide and action items, and it reviews the deck alone. When shortlisting any fund, a founder can check whether the fund leads at the founder’s stage and whether it has followed on in comparable companies.
FAQ
Q: How long should a deck be after revisions?
A: There is no single right length, because it depends on the company and on what needs explaining. In the Papermark data, 46 percent of decks run 9 to 16 pages, which makes that range a useful reference point. A deck works best when it is as concise as it can be while still making the case clearly.
Q: Where do deck readers sit?
A: Two thirds of tracked deck views in the Papermark data came from outside the United States. For that reason, a line naming the market the company serves can help readers who do not know it.
Q: What does the Pitch Deck Evaluator give founders, and is the deck stored?
A: It gives instant insights into what is working, what is missing and what can be improved in a pitch deck, plus an investor takeaway for each slide and action items derived from the deck. It also covers how to prepare for investor meetings. The deck is processed temporarily for evaluation only and never stored, and no human reads it. Founders with specific confidentiality requirements can read the Privacy Policy and the Terms of Use before submitting a deck.
Q: Which companies has Grove Ventures backed?
A: Grove invests in Israeli founders from pre-seed and seed through Series A across Enterprise AI, Semiconductors, AI infrastructure and compute, Vertical AI, Physical AI, Healthtech and Energy. Managing Partner Lior Handelsman, who co-founded SolarEdge, works with the portfolio alongside the firm’s other partners, who also built and scaled companies themselves. Grove led an $8 million round in Teramount in 2021 and kept backing it until Molex completed the acquisition on 7 May 2026. It also led the 2025 seed round of Limitless Labs, which applies physics-based AI to CNC programming, and took part in NoTraffic’s rounds from its 2021 Series A through its 2026 Series C.
Q: How do Grove, Hetz and StageOne differ?
A: Grove invests from pre-seed and seed through Series A across Enterprise AI, Semiconductors, AI infrastructure and compute, Vertical AI, Physical AI, Healthtech and Energy, Hetz focuses on cybersecurity, data and AI infrastructure at seed, and StageOne backs Israeli enterprise technology founders at the inception stage.
