Validate pitch deck

You must: (1) PROBLEM. cite specific evidence: user interviews (count, key quotes where THEY raise the pain), quantified existing spend on workarounds, frequency of pain occurrence. "We believe" is not evidence. "23 of 30 interviewees spend $200+/month on workarounds" IS evidence, (2) MARKET. TAM/SAM/SOM with named sources, year, and methodology. Bottom-up preferred (customer count × ACV). Top-down acceptable if sourced (Gartner, IDC, Statista), (3) MODEL. revenue mechanic, specific pricing, and unit economics: CAC by channel, LTV adjusted for gross margin, LTV/CAC ≥ 3x, payback ≤ 12 months, gross margin ≥ 65%, (4) TRACTION. retention-based metrics: MRR/ARR, NRR, paid conversion, cohort retention. Downloads, signups, and waitlist are NOT traction, (5) ASK. exact amount, allocation by category (%), milestones with measurable targets, runway in months, and the metric milestone that unlocks next round. If rejected, the deck has an investor-visible weakness. Fix before presenting. Structured reflection capability for pitch deck validation. forces evidence-backed problem validation, rigorous market sizing with named sources, unit economics verification, traction beyond vanity metrics, and specific fundraising asks with milestone-linked runway before any investor-facing deck ships. Catches Problem Fabrication (building a solution for a problem the founder experiences but the market does not. "We built an AI that auto-categorizes Slack messages." Founder's evidence: "I have 47 channels and can never find anything." Reality check: 23 customer discovery interviews revealed 0 people who would pay for this. Why? Heavy Slack users already use channels-as-categories. Light users have 5-8 channels. The "problem" exists for the founder but not at market scale. Evidence required: 30+ user interviews where the INTERVIEWEE raises the pain unprompted (The Mom Test: never ask "would you use this?". ask "walk me through the last time this happened"), quantified existing spend on workarounds ($X/month on Notion/bookmarks/manual search), and frequency data (how often does the pain occur? Daily = urgent. Monthly = nice-to-have)), Market Fantasy (claiming a TAM without sourcing or methodology. "The global communication capabilities market is $45B." This number is real (Gartner 2024). But it includes: enterprise telephony ($12B), video conferencing ($8B), unified communications ($15B), and team messaging ($4B). A Slack message categorizer competes in team messaging productivity ($4B). Of that, the segment who would adopt a third-party Slack add-on (not built by Salesforce) in companies with 50-500 employees is approximately $120M (SAM). Achievable in 18 months with current go-to-market: $2M (SOM). "$45B market" vs. "$2M obtainable in 18 months". investors fund the latter), Unit Economics Absent (showing revenue without proving the business can be profitable. "We have $50K MRR!" Investors ask: CAC? "$1,200 blended." LTV? "$3,600 at 24-month median lifetime." LTV/CAC ratio: 3.0x. Sounds healthy. But: gross margin is 35% (heavy infrastructure costs. GPU compute for AI features). LTV adjusted for gross margin: $3,600 × 0.35 = $1,260. Adjusted LTV/CAC: 1.05x. The business DESTROYS value with every customer acquired. Gross margin below 60% for SaaS is a structural problem. not a growth problem. Raising money accelerates losses, not profits), Vanity Traction (presenting engagement metrics that do not predict revenue. "100,000 downloads! 50,000 signups! 10,000 DAU!" Investors ask: "What percentage converts to paid?" "2%." "What is Day-30 retention?" "8%." 100,000 downloads × 2% conversion × 8% retention = 160 retained paying users. At $10/month: $1,600 MRR. That is the real traction. not 100,000 downloads. Traction metrics that matter: MRR/ARR, net revenue retention (NRR > 100% = expansion revenue), paid conversion rate, cohort retention (Day 1, 7, 30), and payback period. Downloads, signups, waitlist size, and "strong interest" are vanity metrics. they measure curiosity, not commitment), and Vague Ask (requesting capital without specifying allocation, milestones, or runway. "We are raising $2M to scale." Scale what? How? Over what period? Investor-grade ask: "$2M Seed. 18-month runway at $111K/month burn rate. Allocation: 55% engineering (3 senior hires + infrastructure), 25% sales (1 AE + SDR + CRM tooling), 15% marketing (content + paid acquisition at target CAC $800), 5% operations (legal, accounting, office). Milestones: Month 6. product-market fit signal (NPS > 40, Day-30 retention > 25%). Month 12. $30K MRR. Month 18. $80K MRR, position for Series A at 3x revenue multiple = $2.88M ARR."
