Kill Your Idea Before You Build It
Idea Validation System
Most idea-validation tools are cheerleaders: you describe your idea, a chatbot tells you it is brilliant, and you feel validated without learning anything. This pack does the opposite — every prompt casts Claude as a skeptical analyst whose job is to find the reason your idea dies, not to flatter you. Every number it cannot stand behind is labelled a guess with the math shown, so you never mistake a made-up figure for a fact. It runs on the frameworks real founders use — bottoms-up market sizing, the Mom Test, the Riskiest Assumption Test, Van Westendorp pricing — and it is tuned for a price-sensitive India and Brazil reality where 'build the app' is usually the wrong first move. A green light here means your idea survived an honest attack, not that a bot told you what you wanted to hear.
What you'll be able to do
Stress-test your idea before you spend a rupee: a bottoms-up market size, a real competitor map, a customer-interview guide, the cheapest test that could kill it, a value-based price, and a pitch — every one run by a skeptical analyst, not a cheerleader.

What's inside
- 01Claude Cowork
Size Your Market Honestly
Run this first. Give it your idea, who pays, and the price — it builds a bottoms-up estimate as an equation where every number is labelled a fact, an assumption, or a guess, then cross-checks it top-down.
Example · Input
A ₹99/month tiffin-tracking app for working parents in Pune.
Example · Output
A bottoms-up equation (reachable customers × annual value), TAM / SAM / SOM, a top-down cross-check with reconciliation, low/base/high scenarios, and the 2–3 assumptions to go verify.

Map Your Real Competition
Use this to see who you are actually up against — including the do-nothing option founders forget. Paste your idea and any rivals you know; it fills a four-bucket table and marks anything it cannot verify.
Example · Input
An app that helps home bakers in São Paulo take custom cake orders.
Example · Output
A table bucketed into Direct / Indirect / Substitute / Status-quo with price and weakness per rival, a two-sided switch test, and a verdict on whether you are differentiated or a me-too.

Interview Customers Without Lying To Yourself
Use this before you build anything. Tell it your idea and who the customer is; it writes a Mom Test interview guide with zero leading questions, so 5–10 conversations give you truth, not compliments.
Example · Input
I want to help small kirana shops track udhaar (customer credit) on their phone.
Example · Output
8–12 past-oriented questions, a 'never ask these' list with why each generates lies, a don't-pitch rule, and signal-reading guidance that counts only time or money already spent.

Find The Cheapest Test That Could Kill It
Use this to avoid building the wrong thing. Give it your idea and your time and budget; it names the one assumption that sinks everything and designs a near-free, no-code test with a kill criterion set in advance.
Example · Input
A subscription box of regional snacks for NRIs, ₹1,500/month.
Example · Output
Assumptions ranked by risk, a falsifiable hypothesis with a pass/fail threshold, a recommended MVP type (landing page / Concierge / Wizard-of-Oz), a short IN list, a long OUT list, and a 1–2 week plan costing near zero.

Price It On Value, Not Guesswork
Use this when you do not know what to charge. Give it the value to the customer and what alternatives cost; it prices from value, hands you the four Van Westendorp questions to ask real prospects, and reality-checks for a price-sensitive market.
Example · Input
A WhatsApp bot that answers legal FAQs for gig workers in India.
Example · Output
Value-first math, the exact four Van Westendorp price questions, a recommended range in ₹ with anchoring guidance, a metro-vs-tier-2 reality check, a 'why free is dangerous' note, and a WTP test plan.

Decide If You Should Even Raise
Run this last, after the other five. Paste their outputs; it first tells you honestly whether to raise or bootstrap, and only if yes drafts a deck narrative from your real evidence — pre-mortem included.
Example · Input
Pre-seed idea + my market-size, competitor, and pricing outputs; I think I need ₹40 lakh.
Example · Output
A 'should you raise?' verdict first, then a slide-by-slide outline (Problem to Ask) filled with your real numbers, an Ask framed as milestones and runway, and a 'weakest part of your pitch' pre-mortem.
