Investor decks are designed to persuade. Every chart is chosen, every comp is flattering, every projection is hedged. So I stopped reading decks like documents and started running them through a pipeline. Drop the PDF into the model. Have it extract every quantitative and forward-looking claim, slide by slide. Classify each as fact, projection, opinion, or omission. Then score against six recurring red flags: cherry-picked windows, adjusted-metric inflation, flattering comp sets, top-down TAM math, hidden dilution, soft hedge language. The output is a matrix, not a verdict. Each row maps a claim to the primary source that settles it: the 10-K reconciliation, the proxy cap table, the earnings call Q&A. The model builds the matrix. You run the verification. The most dangerous slide is still the one with no number on it. Human judges. AI builds. Comment MATRIX and I will send you the full prompt as a PDF. Educational only. Not investment advice.

WHY A DECK IS NOT EVIDENCE
A pitch deck is a sales document. Every chart is chosen, every cohort is curved, every comp is flattering. The job is not to read it. The job is to interrogate it.
- The common mistake: treating a clean slide as a clean fact.
- The failure mode: you anchor on the narrative and skip the filing.
- The discipline: convert claims into questions, then route each question to a primary source.
- Human judges. AI builds. The model extracts and structures. You decide what holds up.
Why it matters: persuasion lives in framing and omission. A matrix forces every claim into the open where it can be checked or killed.
THE WORKFLOW IN 5 STEPS
Run the same pipeline on every deck so your scrutiny is consistent, not mood-dependent.
| Step | Action | What you get |
|---|---|---|
| 1 Ingest | Drop the PDF into the model. Ask it to list every quantitative and forward-looking claim. | A clean claim inventory, slide by slide |
| 2 Classify | Tag each claim: fact, projection, opinion, or omission. | Separates verifiable from unverifiable |
| 3 Score | Apply the red-flag rules below to each claim. | A severity rating per line |
| 4 Route | Map each claim to a primary source to confirm or refute. | A verification checklist, not a vibe |
| 5 Memo | Export the matrix into your IC note as the open-questions section. | An audit trail of what you checked |
Tip: do not let the model conclude. It builds the matrix. You run the verification and write the judgment.
THE RED-FLAG MATRIX
Six recurring patterns in polished decks. Each row is a prompt you can paste, plus the source that settles it.
| Red flag | What to ask the deck | Where to verify |
|---|---|---|
| Cherry-picked window | Why does the chart start in this year? Show the full history. | 10-K trend tables, prior filings |
| Adjusted metric inflation | Reconcile adjusted EBITDA to GAAP. What was added back? | 10-K, 10-Q reconciliation footnotes |
| Flattering comp set | Who is excluded from the comps and why? | Peer 10-Ks, sector screen, multiples |
| TAM math | Is this top-down market size or bottom-up demand? | Customer counts, unit economics, churn |
| Hidden dilution | Show fully diluted share count with SBC and converts. | Cap table, proxy, options footnote |
| Soft hedge language | What would have to be true for this projection to break? | Earnings call Q&A, guidance history |
Heads up: the most dangerous slide is the one with no number on it. Omission is a claim too.
SEVERITY SCORING
Not every flag kills a thesis. Rank them so the matrix drives action instead of noise.
| Level | Meaning | What it does to your work |
|---|---|---|
| Critical | Claim is central to the thesis and unverifiable from primary sources. | Pause. Do not size until resolved. |
| Material | Real gap between deck framing and the filing. | Adjust the model. Document the delta. |
| Watch | Minor framing spin, low thesis impact. | Note it. Track at next earnings. |
| Clear | Claim ties cleanly to a primary source. | Mark verified. Move on. |
Why it matters: a Critical flag is a position-sizing input, not a footnote. Size to what you can verify, not to what you were shown.
STARTER PROMPT
Paste this with the deck attached. Edit the brackets for your mandate.
- Role: You are a buy-side analyst reviewing this investor deck for [company].
- Task: Extract every quantitative and forward-looking claim, slide by slide.
- Classify each as fact, projection, opinion, or omission.
- For each, apply these red flags: cherry-picked window, adjusted metric, comp set, TAM math, dilution, soft language.
- Output a table: Claim | Slide | Type | Red flag | Severity | Primary source to check.
- Do not draw a conclusion. List only what I need to verify. No buy, sell, or hold language.
Key: the constraint 'do not conclude' is load-bearing. It keeps the model in the builder seat and you in the judge seat.
GUARDRAILS
- The model hallucinates citations. Open every filing yourself before trusting a number.
- A deck PDF can omit the appendix. Confirm you have the full document, not the roadshow teaser.
- Matrix completeness is not thesis quality. A clean matrix on a bad business is still a bad business.
- Educational workflow only. This produces questions to research, never a recommendation to act.
Heads up: the matrix tells you what to check. It does not tell you what to buy.

Visual design notes
- Canvas 1080x1350, warm paper bg #fbfaf6. Near-black ink #191919 for text and borders, ONE teal accent #15d6d6. Coral #d97757 reserved only for the title accent word and severity Critical chip.
- Header centered: H1 in Sergio Trendy uppercase, two lines with break after 'INVESTOR DECK TO'. Emphasize 'RED-FLAG' in teal, rest in ink. Teal subtitle banner bar directly below the title spanning full content width.
- Hero element: 'THE RED-FLAG MATRIX' is the visual anchor. Render it as a heavy 3-column table with first column (red flag name) on beige #f5f2ea background, bold. All internal grid lines 1.5px solid ink, outer card border 3px ink with a 5px teal hard shadow.
- Section labels as black bars with white uppercase Montserrat 900 text, teal 3px bottom border, with 8px breathing room before the table beneath.
- Severity Scoring table uses small status chips in the Level cell: Critical = coral, Material = ink, Watch = teal-pale, Clear = teal. Keep chips as the only place coral appears in body.
- Starter Prompt section styled as a dark terminal-style card: #191919 bg, white monospace-leaning text, teal prompt markers, teal hard shadow. This breaks up the table density with one dark block.
- Alternating density: the 5-step and matrix tables are dense; follow each with a single 'Why it matters' note line in teal-pale callout for breathing room. main gap 20-24px, padding 18-20px 32px 20px.
- All content left-aligned inside cards. Vertical-align middle on every table cell. No gray text anywhere: ink on light, white on dark.
Production checklist
- ☐Design the 6-section one-pager in the WSP template at 1080x1350 with paper bg, ink text, single teal accent; coral only on title word and Critical chip.
- ☐Build the four tables: 5-step workflow (3 col), red-flag matrix hero (3 col), severity scoring (3 col with status chips), plus the bulleted starter prompt as a dark terminal card.
- ☐Apply table rules: beige first column, 1.5px ink internal grid, 3px ink outer border, teal hard shadow on hero; vertical-align middle; no gray text.
- ☐Add header (two-line Sergio Trendy title + teal subtitle banner) and footer (Follow Dave Wang · Wall Street Prompt · COMMENT & REPOST with avatar).
- ☐Verify at 100% zoom that all six sections and the footer fit inside 1350px with no overflow; check section-to-section gap follows the 20-24px scale.
- ☐Export PNG 1080x1350 at 2x via html-to-image (toDataURL path) and PDF via jsPDF for DM delivery; name files YYYY.MM.DD_From Investor Deck to Red-Flag Matrix.
