How to evaluate a pitch deck
Evaluating a pitch deck means deciding, from the slides alone, whether a company has earned a first meeting and what to ask in it. A good evaluation reads the deck twice. The first read is for the story: the problem, the customer, why now, the team and what the money is for. The second treats the deck as evidence, tracing every figure to its slide, pinning down what each metric means and testing the numbers against each other.
Read for definitions as much as numbers. A figure can be accurate on one definition and misleading on another, and a slide may not say which one it used.
Screen the pitch deck for fit first
Most decks you see won't become investments, so screen quickly. In a 2016 study, researchers at Harvard, Stanford and the University of Chicago surveyed 885 venture capitalists. Their firms considered roughly 100 opportunities for each deal they closed1 and met the management team in about one case in four.
Start with your own criteria: stage, sector, location, round size and the check you'd write. About half the investors in that survey called fit with their fund important. If the deck fits, read it straight through once, without stopping to calculate.
Read it once for the story
Sequoia Capital asks founders to define the company in a single declarative sentence2 before anything else. After your first read, try writing that sentence yourself. If you can't, that's your first question. Then check that each part says something specific.
What each part of the deck should establish
| Part | What it should show | What to check |
|---|---|---|
| Problem | Whose pain it is, and how they cope today | A specific customer, not a whole industry |
| Why now | What changed to make this possible | A real shift in cost, rules or technology |
| Market | Who buys, how many, at what price | Counted up from customers, not a slice of a big total |
| Traction | What is already working | Monthly figures, not cumulative charts |
| Business model | Who pays, how much and how often | Customers times price lands near the revenue shown |
| Competition | Other ways customers solve this, including doing nothing | Named alternatives, not "no competitors" |
| Team | Why these people can win | Experience that fits this problem, and any key gaps |
| The ask | How much, on what terms, for what | Months of runway bought, and milestones promised |
Give the team slide real weight. In the same survey, 47% of respondents named the management team the most important factor1 in choosing investments. Only 37% named a business factor, such as the product or market.
List every figure and where it came from
On the second read, open a spreadsheet and give every number a row: the figure as written, its slide, and one of three labels.
- Stated: printed on a slide. Copy it word for word.
- Derived: worked out by you from stated figures, such as a growth rate from two revenue numbers. Keep the arithmetic.
- Missing: an input another figure needs that the deck never gives, such as the churn rate behind a lifetime value.
The labels keep your own arithmetic from passing as the company's claim in the write-up. Read the charts as closely as the numbers. The venture firm Andreessen Horowitz warns that cumulative charts can rise even while a business shrinks3. It also flags an unlabeled y-axis, a scale shrunk to exaggerate growth, and percentages without the absolute numbers.
Pin down what each metric means
Which number a deck calls its top line can flip the story. In its full-year 2025 results4, Etsy reported gross merchandise sales down 5.3% to $11.9 billion and revenue up 2.7% to $2.88 billion. A deck could truthfully call that business shrinking or growing, depending on which line it printed.
Etsy's release also notes that selling its Reverb marketplace in June 2025 affected every year-over-year comparison. Decks rarely explain their figures like that, so for each metric the case rests on, write down the possible meanings and ask which one applies. Andreessen Horowitz's guide to 16 startup metrics3 covers the most common or confusing ones.
Metrics to define before you rely on them
| Metric | Ask | Why it matters |
|---|---|---|
| ARR | Recurring fees only? Signed contracts, or customers already paying? | ARR should leave out one-time and professional service fees |
| Revenue | Everything customers spent, or the company's cut? | In a marketplace, sales volume is not revenue |
| Bookings and pipeline | Signed contracts, or letters of intent? | Letters of intent are neither revenue nor bookings |
| Retention | Customers or revenue? Monthly or annual? After upsells? | Net figures blend upsells with losses, which understates churn |
| Acquisition cost | Paid channels only, or blended with free signups? | A blended figure makes paid growth look cheaper |
| Lifetime value | Revenue, gross margin or contribution? Over what lifespan? | Lifespan is 1 ÷ churn, so it moves with churn |
| Active users | Active doing what, and how often? | There's no standard meaning of "active" |
Test the numbers against each other
A deck's figures depend on each other, so check them in pairs, using only its own numbers.
- Revenue ÷ customers, against the price on the pricing slide
- This year's revenue ÷ the growth multiple, against last year's figure
- Acquisition cost ÷ monthly gross profit per customer, against the payback claimed
- 1 ÷ churn, against the customer lifespan behind the lifetime value
- Cash after the round ÷ planned monthly net burn, against the runway and milestones promised
Slide 4: ARR $2.4M, up 3x year on year.
Slide 5: 1,400 customers, 92% retention.
Slide 9: CAC $4,800, LTV $16,000, payback in 15 months.
- Derived. $2.4M ÷ 1,400 is about $1,714 a year per customer, or $143 a month. Label it derived.
- Contradiction. At $143 a month, $4,800 takes about 34 months to earn back from revenue alone, before any costs. Slide 9 says 15.
- Undefined. If 92% is monthly, the average customer stays about 12.5 months; if annual, 12.5 years. A $16,000 LTV needs more than 9 years of revenue.
- First question. "Slide 9 shows a 15-month payback. Which revenue and cost figures is that based on?"
A gap like this may have a plain explanation, such as new customers paying more than older ones, so it becomes a question, not a verdict. To rebuild these figures from cohort data later, use a unit economics model.
Turn the gaps into first-call questions
Rank your questions by how much the answer could change your view, with contradictions first. Name the slide and figure in each. Ask what the deck means, not whether the founder is honest: you'll get a straighter answer, and keep the relationship if you invest.
In the US, a startup raising privately from accredited investors only has discretion over what it discloses5, though what it does say must not be misleading. The SEC's investor bulletin says investors in private placements are generally on their own in getting the information they need.
So beside each question, note the document that would settle it: monthly revenue by customer, a cohort table, bank statements or the signed contracts behind a pipeline. A startup data room checklist shows what a well-prepared company keeps on hand.
Before the first call
- You can say in one sentence what the company does, and for whom
- Every figure has its slide and a label: stated, derived or missing
- Each key metric is defined, or has a question asking for one
- Each contradiction names both figures and both slides
- Questions are ranked by how much the answer could change your view
- Each open question names the document that would settle it
A deck review isn't diligence
It tells you what to ask, not whether to invest. Before you sign, have a lawyer review the investment documents. The SEC's bulletin also says you should be able to afford the potential of a total loss5.
The tool at the top of this page drafts the figure list, cross-checks and questions from the deck itself. When the deal moves forward, the investment committee memo template carries each headline figure on two definitions: the deck's, and the one diligence supports.
How it works
Start by attaching the deck as a PDF or pasting its slides, with any appendix, model or call notes you have. River reads all of it, lists every figure with its slide, does the arithmetic and tests the numbers against each other. It writes a first read into your workspace, with the questions to ask first and the documents that would answer them. It gives no score or verdict: the decision stays yours.
Send the deck
Attach the PDF or paste the slides. A financial model, one-pager or call notes help too.
River checks every figure
Each number is traced to its slide, recalculated where possible and tested against the rest of the deck.

Common questions
What do investors look for in a pitch deck?
A team suited to the problem, a specific customer in real pain, evidence that something is working and a sensible plan for the money. In a 2016 study of 885 venture capitalists, 95% of respondents called the management team important1. Next came the business model at 83%, the product at 74% and the market at 68%.
What are the red flags in a pitch deck?
The serious ones are figures that don't reconcile and metrics that are never defined. Look for revenue that doesn't match customers times price, cumulative charts in place of monthly figures and unlabeled chart axes. Watch, too, for retention with no stated basis, letters of intent counted as bookings, and a raise too small for the milestones promised. Treat each as a question, not proof of bad faith.
How long should it take to evaluate a pitch deck?
A few minutes to screen it, an hour or two to read it properly, and weeks if you go on to diligence. Check fit first, then read once for the story and once with a spreadsheet. Professional investors go much further before committing. In a 2016 study, venture firms spent an average of 118 hours on due diligence1 per deal, and the average deal took 83 days to close.
How do I evaluate a pitch deck with River?
Attach the deck as a PDF or paste its slides in the box at the top of this page, and pick where you are with the deal if you like. River lists every figure with its slide, checks them against each other and flags undefined metrics. The findings and ranked questions open in your free River workspace, with a sheet of every figure.
Does the tool tell me whether to invest?
No. The pitch deck analysis gives no score, rating or recommendation, because what a deck establishes and whether a company is a good investment are different questions. You get what the deck supports, what it leaves undefined and what to ask next. It won't compare the company with outside benchmarks unless you supply them, and it says which ones it would need.
Can founders use this tool on their own deck?
Yes. Run your deck through it before you send it. You'll see what a careful investor sees: figures that can't be checked, slides that disagree and the questions you're likely to get. Then fix the definitions on the slides themselves. For margin notes in an investor's voice, try pitch deck feedback from a seed investor.
Is the pitch deck analysis tool free?
Yes, it is free to start. Your deck review opens in a River workspace, where you can edit it, share it or ask River to change it. Paid plans add more AI use and access to the most advanced models.
