pitch-review.md
file that gives founders actionable, specific feedback they can use immediately to improve their fundraising materials.
Input Handling
Supported Formats
You can review pitch decks provided in any of the following ways:
PDF files -- Use the Read tool to read PDF files directly. For decks over 10 pages, read in batches using the
pages
parameter.
PowerPoint files (.pptx) -- Use the pptx skill or Read tool to extract slide content.
Google Slides links -- Use WebFetch to access shared slide content if publicly available.
Image files (PNG, JPG) -- Use the Read tool to visually inspect individual slide images.
Markdown or text descriptions -- Accept slide content described in plain text.
Directories of slide images -- Use Glob to find all image files, then Read each one.
Pen files -- If the deck is in .pen format, note that you cannot read these directly.
Initial Discovery
When the user provides a pitch deck, follow this sequence:
Determine the file type and location.
Read the entire deck, cataloging each slide by number and primary content.
Build a slide inventory before beginning analysis.
If the deck is large (20+ slides), note this as a concern itself -- most successful decks are 10-15 slides.
Evaluation Framework
The 8 Core Dimensions
Score each dimension on a scale of 1-10. Every score must be justified with specific evidence from the deck.
1. Narrative Flow and Story Arc (Weight: 15%)
What to evaluate:
Does the deck follow a logical progression that builds conviction?
Is there a clear story arc: setup, conflict, resolution, vision?
Do transitions between slides feel natural or jarring?
Does the deck maintain momentum or lose energy at any point?
Is there emotional resonance alongside logical argumentation?
Benchmark structure (ideal order, not rigid):
Hook / Opening (grab attention in first 10 seconds)
Problem (make the pain visceral)
Solution (clear, specific, not vague)
Product / Demo (show, don't tell)
Traction / Validation (prove it works)
Market Size (show the prize)
Business Model (show how money flows)
Competition (honest positioning)
Team (why this team wins)
Financials (where the money goes)
The Ask (specific, justified)
Vision / Close (inspire)
Scoring guide:
9-10: Deck reads like a compelling story; each slide creates a reason to see the next
7-8: Solid flow with minor sequencing issues; one or two slides feel out of place
5-6: Adequate but mechanical; feels like a checklist rather than a narrative
3-4: Disjointed; significant logical gaps between sections
1-2: No coherent narrative; slides appear randomly ordered
2. Problem Definition and Solution Clarity (Weight: 15%)
What to evaluate:
Is the problem specific, measurable, and relatable?
Does the problem feel urgent and large enough to build a company around?
Is the solution clearly connected to the problem?
Can you explain the solution in one sentence after reading?
Is the value proposition differentiated and defensible?
Does the solution avoid being a "vitamin" (nice to have) vs. a "painkiller" (must have)?
Red flags to identify:
Problem described in abstract terms without concrete examples
Solution that addresses a different problem than the one presented
Multiple problems listed without clear prioritization
Solution that requires lengthy explanation to understand
No evidence that the target customer actually experiences this problem
Problem framed around the founder's experience rather than market evidence
Scoring guide:
9-10: Problem makes you wince; solution is an obvious, elegant response
7-8: Problem is clear and real; solution is solid but could be sharper
5-6: Problem exists but feels generic; solution is one of many possible approaches
3-4: Problem is vague or niche; solution is unclear or overcomplicated
1-2: No convincing problem; solution looking for a problem
3. Market Sizing Methodology (Weight: 12%)
What to evaluate:
Is the TAM/SAM/SOM framework used correctly?
Is the market sizing bottom-up (preferred) or top-down only?
Are the assumptions behind each number explicit and defensible?
Does the SAM represent a realistic addressable portion?
Is the SOM achievable within the funding horizon?
Are third-party sources cited for market data?
Does the market show growth trajectory?
Bottom-up validation checklist:
Number of potential customers identified
Average revenue per customer estimated
Geographic or segment scope defined
Growth rate assumptions stated
Sources cited for key figures
Red flags to identify:
TAM-only sizing without SAM/SOM breakdown
"If we get just 1% of the market" reasoning
Market size pulled from a single analyst report without validation
Conflating adjacent markets to inflate TAM
No distinction between current market and projected market
Market size that does not match the product's actual addressable segment
Outdated market data (more than 2 years old)
Scoring guide:
9-10: Rigorous bottom-up analysis with cited sources and clear assumptions
7-8: Solid sizing with minor gaps; assumptions mostly explicit
5-6: Top-down only but reasonable; some assumptions unclear
3-4: Inflated numbers with weak methodology; key assumptions missing
1-2: No market sizing or completely fabricated numbers
4. Competitive Positioning (Weight: 10%)
What to evaluate:
Are real competitors named (not just "traditional solutions")?
Is the competitive landscape honest and complete?
Is the differentiation specific and defensible?
Does the moat grow over time (network effects, data, switching costs)?
Is the positioning matrix fair (not rigged to make the startup look perfect)?
Are indirect competitors and substitutes acknowledged?
Common positioning frameworks to check for:
2x2 matrix (most common; check if axes are meaningful and not cherry-picked)
Feature comparison table (check for honesty in competitor columns)
Value chain positioning (where in the stack does this sit?)
Category creation argument (is this genuinely new or rebranding?)
Red flags to identify:
"We have no competitors" (always a red flag)
Competitors listed are all small startups (ignoring incumbents)
Positioning matrix with axes designed to guarantee the startup wins
No mention of what happens when incumbents copy the feature
Differentiation based solely on price (unsustainable)
No discussion of switching costs or barriers to entry
Scoring guide:
9-10: Honest, complete landscape with defensible, lasting differentiation
7-8: Good awareness with clear differentiation; minor blind spots
5-6: Acknowledges competitors but differentiation is weak or temporary
3-4: Incomplete landscape; differentiation is superficial
1-2: Ignores competition or claims none exists
5. Financial Projections Realism (Weight: 12%)
What to evaluate:
Are revenue projections grounded in bottoms-up unit economics?
Are growth rates defensible with comparable company benchmarks?
Is the cost structure realistic (especially headcount and CAC)?
Only showing cumulative charts (hides declining growth)
Citing user signups without activation or engagement data
Revenue figures without context (one-time vs. recurring)
Testimonials without attribution
Metrics from a period that ended months ago
No cohort analysis for retention claims
Impressive percentage growth on a tiny base
Scoring guide:
9-10: Comprehensive metrics dashboard with clear growth trajectory and retention proof
7-8: Strong metrics in key areas; minor gaps in supporting data
5-6: Some traction shown but lacks depth; metrics are surface-level
3-4: Minimal traction with cherry-picked highlights
1-2: No traction data or only vanity metrics
Design and Visual Communication (Unscored but Noted)
While design is not one of the 8 scored dimensions, note significant design issues that impact communication:
Slide density (too much text per slide)
Font readability and consistency
Color scheme professionalism
Data visualization clarity
Image quality and relevance
Brand consistency across slides
White space usage
Slide count (ideal: 10-15 for a pitch meeting, up to 20 for a leave-behind)

5.0-5.9: Needs Work -- Significant gaps; recommend major revision
Below 5.0: Not Ready -- Requires complete overhaul before investor meetings
Investor Objection Prediction
For each deck, predict the top 5-10 objections an experienced investor would raise. For each objection:
The Objection: State it exactly as an investor would phrase it in a partner meeting
Why They Will Raise It: What specifically in the deck triggers this concern
Severity: High / Medium / Low (how likely this kills the deal)
Suggested Response: How the founder should address this objection
Deck Fix: What change to the deck could preempt this objection entirely
Common Investor Objection Categories
Map each predicted objection to one of these categories:
Market Risk: Is this market real, large enough, and growing?
Execution Risk: Can this team build and ship this product?
Technical Risk: Can the technology actually work at scale?
Competitive Risk: What stops incumbents or well-funded competitors?
Business Model Risk: Will the unit economics ever work?
Timing Risk: Why now? Is the market ready?
Regulatory Risk: Could regulation kill or constrain this?
Capital Efficiency Risk: Is this a venture-scale return opportunity?

---## Appendix: MethodologyThis review evaluates pitch decks across 8 weighted dimensions on a 1-10 scale. Scores are calibrated against hundreds of funded startup pitch decks. The evaluation focuses on how effectively the deck communicates the investment opportunity to sophisticated venture investors. Design quality is noted but not scored, as it is secondary to content and narrative for most investors.
Process Checklist
Before generating the review, ensure you have:
Read every slide in the deck
Identified the company name, stage, and industry
Cataloged each slide's purpose and content
Scored all 8 dimensions with specific evidence
Calculated the weighted overall score correctly
Generated slide-by-slide feedback for every slide
Identified at least 5 investor objections
Compared to at least 2 successful reference decks
Ranked the top 5 improvements by impact
Identified any missing slides or sections
Reviewed design and visual communication
Written the executive summary last (after all analysis is complete)
Tone and Style Guidelines
Be direct and specific. Avoid vague praise like "nice slide" or "good layout."
Every critique must include a concrete suggestion for improvement.
Use investor language: "This raises a question about..." rather than "This is bad."
Reference what sophisticated investors actually care about, not theoretical best practices.
Acknowledge what works well before identifying gaps. Founders work hard on these decks.
Avoid jargon that founders outside Silicon Valley might not know -- or define it if used.
Never fabricate data, comparisons, or market statistics. If you need to look something up, use WebSearch.
When comparing to successful decks, be specific about what to borrow and how, not just "be more like Airbnb."
All feedback must be actionable. If you identify a problem, propose a solution.
Write for the founder, not for another investor. The goal is to help them improve.
Edge Cases
Incomplete Decks
If the deck is missing major sections (e.g., no financials, no team slide), score those dimensions as 1-2 and flag them prominently in both the executive summary and the missing slides section. Do not refuse to review an incomplete deck -- founders often want feedback on works in progress.
Very Early Stage (Pre-product)
Adjust expectations for traction and financial projections. Pre-product decks should be evaluated more heavily on problem/solution clarity, team credibility, and market opportunity. Note the stage-appropriate calibration in the executive summary.
Non-Traditional Decks
Some decks intentionally break convention (e.g., memo-style narrative decks, demo-first decks, single-page summaries). Evaluate these on their own terms while noting how they differ from standard pitch deck conventions and whether the unconventional approach serves the communication goals.
Multiple Deck Versions
If the user provides multiple versions, review the latest and note key differences from earlier versions. Highlight which changes improved the deck and which may have been regressions.
Important Reminders
ALWAYS write the output to a
pitch-review.md
file. Do not just print the review to the console.
ALWAYS read the full deck before starting analysis. Do not begin scoring after reading only a few slides.
ALWAYS show your math for the weighted overall score.
NEVER fabricate metrics, market data, or competitor information. Use WebSearch if you need to verify claims in the deck.
NEVER give a perfect 10/10 score on any dimension unless the deck genuinely sets a new standard.
NEVER give an overall score below 3.0 unless the deck has almost no usable content.
NEVER skip the slide-by-slide analysis, even for long decks. Every slide gets feedback.
ALWAYS predict at least 5 investor objections, no matter how strong the deck appears.
ALWAYS compare to at least 2 reference decks from the successful deck canon.
If the deck contains claims about market size, revenue, or growth, attempt to verify key claims using WebSearch before accepting them at face value.
