Pre-launch · Early access for founders
Upload your pitch deck, financial model, and competitive analysis. PitchDeconstruct simulates a ruthless VC partner — finds logic gaps, unrealistic margins, and the 50 hardest questions you'll face in the room.
No credit card · Built on Claude by Anthropic
Founders discover the holes in their pitch only after a partner has already said no — or after spending thousands on advisors and accelerators.

You don't get a second first impression with a top-tier fund. Weak slides burn the intro.

Pitch coaches and accelerators cost thousands. Most founders need a ruthless review, not a program.
Deck ≠ model
TAM on slide 4 vs. unit economics on the spreadsheet — VCs notice. You often don't.
Three steps. One Stress Test report. No softballs.
Pitch deck (PDF), financial model (XLSX/CSV), and competitive analysis. Drop them in — we read slides with charts, not just text.
Claude extracts claims and numbers, critiques each section, then cross-checks the deck against your model like a skeptical GP would.
Logic gaps, unrealistic margins, deck-vs-model mismatches, and 50 ranked questions — sorted by how much they'll hurt.
Value comes from cross-checking your documents and a repeatable report format — not from asking ChatGPT to role-play a VC.
Claude reads your slides including charts and tables — so "hockey-stick" growth claims get checked against what's actually on the page.
Revenue on slide 7 vs. spreadsheet assumptions. CAC/LTV, margins, TAM sizing — flagged when they don't line up.
Deck + model + competitors in a single analysis. Haiku extracts, Sonnet critiques sections, Opus ranks the hardest questions.
JSON-schema output → consistent PDF: findings, severity, and 50 questions ranked by "how much this will hurt."
Example report fragment
MOCK · not a real company## Finding #3 — Severity: HIGH
Claim (deck, slide 6): "70% gross margin at scale"
Model (sheet UnitEcon): COGS implies ~48% GM through Year 3
Gap: No bridge explaining 22pp improvement. Hardware/SaaS mix unclear.
## Question bank (excerpt)
#4 [pain: 9/10] Your model never reaches 70% GM. Walk me through the cost curve that gets you there — or revise the slide.
#11 [pain: 7/10] Which competitors already run at your target margin, and why aren't you using their COGS as a floor?
#27 [pain: 6/10] If GM stays at 48%, does your Series A raise still clear 18 months of runway?
