PitchScan/Pitch deck feedback
Pitch deck feedback: who to ask, what to ignore
Getting feedback on your deck takes an afternoon. Getting feedback worth acting on is the hard part, and nobody warns you that most of what you receive will be confident, well meant and wrong. This is the guide to the sources, the checklist and the filter.
01 · The problem
Feedback is easy to get. Useful feedback is not.
Everyone who opens your deck forms an opinion in under a minute, and almost none of them have any stake in that opinion being correct. You are collecting judgments from people who pay no price for being wrong.
The bad feedback arrives in two shapes. The kind reader (your cofounder, your friends, other founders) optimises for the relationship rather than the document, and tells you the design is clean. The busy reader (investors) optimises for exiting the conversation, and hands you a reason that is polite, unfalsifiable and not the real one.
Both leave you with the same gap. Your deck has one job, which is to make a stranger want the next meeting, and neither reader is telling you what stopped them. So the useful question is never "what did you think of my deck". It is "where did you stop believing me", and you have to design the ask to get that answer.
02 · The sources
Seven places to get feedback, and what each is actually worth.
None of them is the answer on its own. Each is good at one thing and structurally blind to another, so the trick is knowing which blindness you are buying.
| Source | Cost | Good at | The catch |
|---|---|---|---|
| Investors who passed | Free | The only reaction that was priced for real | You rarely get the real reason |
| Founder peers | Free | Speed, and honesty about what confused them | Structurally too kind |
| Programme mentors | Free with the programme | Pattern recognition across many decks | Indexed to their own era and sector |
| Reddit and communities | Free | A stranger's cold read, in volume | Uneven quality, strict self-promo rules |
| Consultants and agencies | Hundreds to thousands | Narrative structure and slide craft | Paid to find work, cannot fix the business |
| Free platform reviews | Free | A second structured opinion at zero cost | Usually a lead magnet, depth varies |
| AI review tools | Free to a few dollars | Mechanical checks, instant and repeatable | No market context, confident regardless |
Investors who passed
The most valuable feedback in existence, and the hardest to extract. A partner who said no did the one thing nobody else did: assessed your deck with money at stake. They will still not tell you why. "Too early for us" and "outside our thesis" are the safe answers, because the honest version ("we did not believe your retention numbers") invites an argument, and arguing with founders they have already declined is not how partners spend a Tuesday.
Asking a narrow question works better than asking for feedback. "Was this a market call or a team call?" is a binary they can answer in six words without opening a debate. "If we hit 100k ARR by March, is that what would change your mind?" gives them something concrete to confirm. Broad requests get platitudes. Narrow ones sometimes get the truth.
Other founders and peers
Fast, free, available at 11pm, and genuinely good at one thing: telling you which slide made them stop reading. Founders who raised recently also carry current information about what a given fund is asking for, which is more perishable than most advice.
The structural problem is that they are too kind, and not because they are weak. You will see their deck next month. The cost of telling someone their market slide is fantasy is real, while the cost of "looks strong, maybe tighten slide 4" is zero. Assume the criticism you get is one notch softer than the criticism they thought.
Accelerator and programme mentors
Mentors are the best pattern matchers you will get for free. Someone who has read 400 seed decks recognises the shape of a deck that will struggle within two slides, and that instinct is worth a lot.
Two failure modes. Advice ages: a mentor who raised in a zero interest rate market pushes growth stories that get you asked about burn today. And mentors default to their own domain, so an enterprise sales mentor finds enterprise sales problems in a consumer deck. Take the pattern recognition, discount the prescriptions to their sector and their era.
Reddit and founder communities
The main venues are r/startups, the largest and most actively moderated, r/venturecapital, which skews toward the investor side of the table and is less patient with founders, and r/startup, which is smaller and noisier. All of them enforce self-promotion rules, and posting a deck link with no context is the fastest way to get removed. Read the sidebar first and post the question, not the pitch.
Quality is genuinely uneven: in one thread you will get a comment from someone who has closed a round and three from people repeating deck advice they read elsewhere. The signal worth taking is the cold read, because strangers with no relationship to protect will tell you plainly that they could not work out what you sell. The signal to discard is the confident prescription from an account with no context.
Paid consultants and deck agencies
Prices range widely. A written review from an independent consultant is often a few hundred dollars, while an agency that rewrites the narrative and redesigns every slide typically lands in the low thousands. What you buy is real: structure, sequencing, a story that builds, slides that do not look like they were made at 2am.
What you do not buy is a different business. No agency turns thin traction into strong traction, and a beautiful deck with an unconvincing market can perform worse, because the emptiness is now obvious rather than hidden behind clutter. Mind the incentive too: a firm whose product is a redesign tends to diagnose a design problem. Ask any paid reviewer to name the one thing they would not change. If everything needs work, the assessment is a quote.
Free reviews from platforms
Several companies give a deck review away, and they are worth using. SaaStr runs a free AI deck analyzer. Slidebean, whose paid business is deck design, offers free analysis. OpenVC, SeedBlink and Evalyze each provide a free review of some form. Running two or three costs an evening.
Read them for what they are. A free review is the top of somebody's funnel, which is not a criticism, just the reason it exists. Depth varies, some are closer to a checklist than an assessment, and none will be harsher than the product they are selling allows. Where they earn their keep is agreement: when three unrelated tools flag your traction slide, that is not a coincidence.
AI review tools
The cheapest pass you will ever run, and genuinely good at mechanical failures: a missing ask, projections presented as traction, a product described before its problem, an unsupported market number, a claim with no source. Those are the errors that get a deck declined without a conversation, and exactly the errors a polite human skims past.
The limits are not marginal. An AI read does not know whether your 2 percent conversion is excellent or dismal for your category, has no idea what a specific partner is currently obsessed with, cannot see your delivery in the room, and will never make an introduction. It is also uniformly confident, which is the dangerous part: it sounds identical whether it is right or guessing. First pass, not last word.
03 · The checklist
What a competent reviewer checks, and why each one matters.
Run this yourself before you spend anyone else's attention. Every item is something a reader decides in seconds and rarely says out loud.
- 01Does the deck hook in the first 7 seconds. The reader decides whether to keep going before they have parsed anything. Slide one says what you do, for whom, and why now, in a sentence a stranger could repeat. A logo on a gradient buys nothing.
- 02Is the problem stated before the product. A product introduced before its problem forces the reader to reverse engineer why it should exist, and most will stop rather than do that work. Problem first is not a convention, it is the order in which belief gets built.
- 03Is traction evidence, not projection. A chart that starts in the future is a forecast, and experienced readers discount forecasts to near zero. Six months of real numbers beats a five year curve every time.
- 04Is the ask explicit, with the milestones it buys. A number alone is not an ask. The reader wants to know how long the money lasts, what it is spent on, and which milestone it reaches, because that turns a request into a plan they can argue with.
- 05Is the market number built bottom up. A top down figure lifted from an analyst report signals you have never counted your actual customers. Customers multiplied by realistic price is a smaller number and a far more credible one.
- 06Is the competition named honestly. "No direct competitors" reads as either you did not look or there is no market, and both are fatal. Naming real alternatives, including the spreadsheet people use today, is a strength.
- 07Does the team slide explain why this team. Nobody is reading resumes. They want the unfair reason that you specifically will get this done, and a list of former employers is not that reason.
- 08Can a stranger repeat your one liner after one read. Decks get forwarded to a partner who was not on the call, so your sentence has to survive being retold by someone with no stake in it. If it cannot, the forward dies in the inbox.
- 09Is every number dated. An undated metric invites the worst available assumption, which is that it is old and no longer true. A date costs nothing and removes an objection you would otherwise face live.
- 10Does each slide carry one idea. When a slide argues three things, a skimming reader retains none. The headline should be the claim and the body should be the evidence for that claim only.
04 · The filter
How to tell useful feedback from confident noise.
Confusion is data. Prescription is opinion.
Exactly one type of comment is always valid: "I did not understand this." A reader cannot be wrong about their own experience of your document. The confusion happened, so it is a defect in your deck regardless of whether you think the slide was clear.
"I would have done it differently" is a different animal. It might be excellent advice, but the evidence behind it is one person's preference. Convert every prescription back into the symptom that produced it. When someone says "put the team slide third", ask what made them say that. Sometimes the answer is that they doubted you could build it, which is a real finding about your credibility. Sometimes the answer is that they saw a deck last week where the team slide came third, which is nothing.
Taste dressed as principle
Much deck advice arrives with the tone of a rule and the substance of a habit. Never more than ten slides. Never full sentences. Always end on the ask. Each is a convention some funds like and others do not notice.
The test is one question: what failure does this rule prevent? "Keep it short because partners skim on a phone between meetings" names a failure mode, so it is a principle you can weigh against your situation. "Ten slides is the standard" names nothing, so it is taste. Taste is not worthless, and a reviewer with good taste is worth hearing, but know which currency you are being paid in.
Weight the reader by proximity to the decision
Advice from someone who has never raised is not automatically bad. Customers are the best judges of whether your problem is real, designers of whether a slide reads. But on what makes an investor take a second meeting, the only people with evidence have been in that room.
One question sorts it out without rudeness: when did you last pass on a deck, and what made you pass? Someone with real reps answers immediately and specifically. Someone recycling advice gives you a general theory of decks. Neither answer disqualifies them, but it tells you how much weight the next twenty minutes deserve.
Know what each reviewer is paid to see
Every bias here is honest. An agency sees a design problem, a finance person sees a model problem, a founder who solved distribution the hard way sees distribution in your deck too, an investor who passed offers the reason least likely to start an argument, and an AI tool is built to produce findings so it will produce some. None of that makes the feedback false. It means you should predict the diagnosis before you read it, and treat what you did not predict as the interesting part.
05 · Contradictions
When two people tell you the opposite, and when to stop.
Contradictory feedback is not a sign that feedback is useless. It is a sign that you are mixing layers. Sort every comment into one of three: comprehension (did they understand the facts), structure (order, emphasis, what leads) and taste (wording, design, length).
Contradictions at the comprehension layer are the most valuable thing in your inbox. If one reader thinks you sell to enterprises and another thinks you sell to consumers, both readings are available in your deck, which means the deck is ambiguous. That is not a disagreement between them, it is a defect in you, and it is usually fixable in one sentence.
Contradictions at the structure layer usually mean the readers have different jobs: a former operator wants the product earlier, an investor wants the market earlier. Pick the reader you are actually sending to and follow that one. Contradictions at the taste layer are noise. Choose either option and never reopen it.
Then apply the rule that beats all of the above: count stumbles, not opinions. Where readers got stuck is far more reliable than what they recommended, because diagnoses conflict constantly while locations converge. If three of five readers slow down on the same slide, that slide is broken even when all three explain it differently and every explanation is wrong.
When to stop. Stop when a full round of readers produces no new severe issue, when two consecutive readers stumble in different places (background noise rather than a pattern), and when the remaining comments are all taste.
Then stop on principle regardless, because the deck is not the product. It exists to get a meeting, not to close the round, so the bar is "no obvious reason to say no" rather than perfection. You will rewrite it anyway once the first five meetings tell you which question actually gets asked, and one more week of polish almost always costs more than one more no.
06 · Worked examples
Three slide fixes, before and after.
The company below is invented and so are its numbers. These are illustrations of a shape of fix, not results from any real deck.
| Slide | Before | After |
|---|---|---|
| Problem | "Invoice reconciliation is broken. The accounts payable market is worth 400 billion dollars and is ripe for disruption." | "A 40 person distributor reconciles about 900 invoices a month by hand. Two people, four days, every month. That is roughly 96 hours of finance time spent on copying numbers." |
| Traction | A curve labelled ARR climbing to 12 million dollars by 2029, with the current point too small to read. | Six bars, one per month of actual revenue, each labelled. Under them, one line: three of the last five pilots converted to paid at an average of 1,400 dollars a month. |
| The ask | "Raising 2 million dollars seed." | "Raising 2 million dollars for 18 months. Takes us from 40k to 150k in ARR, funds three engineers and one salesperson, and reaches the 1 million run rate our Series A targets expect." |
Why the problem fix works
The before version asks the reader to accept an abstraction and a number they cannot verify. The after version describes something they can picture, and quantifies the pain in the customer's own units rather than in market size. The 400 billion figure did not disappear because it was too big. It disappeared because it was doing no work.
Why the traction fix works
The before version is a forecast wearing the clothes of traction, and experienced readers recognise the costume instantly. It also hides the only real information on the slide, which is where you are today. The after version is smaller and more convincing, because six months of actual revenue is evidence and 2029 is a wish. The conversion line turns the numbers into a rate, and a rate is something the reader can project forward themselves, which is a far stronger position than projecting it for them.
Why the ask fix works
The before version leaves the reader guessing whether the amount is sensible, and the guess is usually unflattering. The after version states duration, spend and milestone, which converts the ask into a plan. The second effect is easy to miss: it changes what the reader argues about. They stop wondering whether you have thought about this and start debating whether 150k in ARR is enough for a Series A, which is a conversation you can prepare for.
07 · Where this tool fits
What PitchScan does, stated plainly.
PitchScan is an AI review tool, so everything in the AI section above applies to it, limits included. Here is exactly what it does, so you can place it against the alternatives yourself.
The free scan is one pass in which three condensed partner archetypes evaluate your deck together: The Value Investor (unit economics, business model, defensibility, downside risk), The Growth Partner (market size, timing, traction, momentum, category potential) and The Risk Realist (competition, execution risk, team gaps, regulatory exposure, weak claims). That is 14 named checks. You get a score out of 100, a letter grade, a one line verdict and the top 3 findings. No signup, no card, under 2 minutes, up to 5 scans per day per IP address.
The paid report is 5 dollars, once. Between 7 and 10 personas are selected for your specific deck from a bank of 11, each one reads the deck independently in its own model call, and a meta analysis then reconciles what they said. The design choice worth knowing about is that the personas are not averaged into one voice before you see them: they are allowed to disagree, and the reconciliation step is where the disagreement gets resolved rather than smoothed away in advance.
Whether that is more useful to you than an hour with a founder who has raised in your category, we genuinely cannot tell you. Different failure modes: the tool never gets tired and never softens anything, and it also does not know your market. Most founders should use both, in that order, because the cheap pass should come first.
On your file: the uploaded PDF is deleted immediately after being read. The extracted text is kept for 7 days so that a purchase can be attached to a scan, then purged automatically. It is never used to train models and never shared.
Run a free scan on the homepage if you want the mechanical pass out of the way before you spend a human's attention. If you would rather work through the checklist above by hand first, that is the better order anyway.
08 · FAQ
Questions founders ask about deck feedback.
Where can I get free pitch deck feedback?
Founder communities like r/startups, the mentors attached to any programme you are in, and other founders one stage ahead of you all cost nothing. Several products also give a free review: SaaStr, Slidebean, OpenVC, SeedBlink, Evalyze and PitchScan each offer one. A free review is usually the top of someone's funnel, which is fine as long as you read it knowing that.
How much does a paid pitch deck review cost?
It ranges widely. Independent consultants often quote a few hundred dollars for a written review of a deck you already have, while agencies that rewrite the narrative and redesign every slide are commonly in the low thousands. AI reviews sit at the other end, from free to a few dollars. Price tracks how much human time is involved, not how right the advice turns out to be.
How do I know if the feedback I got is any good?
Separate confusion from preference. When a reader says they did not understand something, they are always right about their own experience, and that is a defect in your deck. When a reader says they would have done it differently, ask what failure that change prevents. If they can name the failure, it is a principle worth weighing. If the answer is that this is simply how decks are done, it is taste.
What should I do when two reviewers give me opposite advice?
Sort every comment into three layers: comprehension, structure and taste. A contradiction in the comprehension layer means your deck is ambiguous, so fix the ambiguity. A contradiction in the taste layer is noise, so pick one option and move on. Then count where readers stumbled rather than what they recommended, because the location of the confusion is far more reliable than anyone's diagnosis of it.
How many rounds of feedback are enough before I send the deck?
Stop when two consecutive readers stumble in different places, when a full round produces no new severe issue, and when the comments you have left are all taste. A deck is not a final exam. You will revise it again after your first five meetings, and one more week of polish usually costs you more than one more no.
