Idea Validation

Kill bad ideas fast. Save time for good ones.

When to Use

• User has a specific idea to test
• Before building anything
• Before spending money on research
• When choosing between ideas

See

example-report.md

for a filled-in validation report showing the depth and format expected.

Process

1. Understand the Idea

Get clear on:

• What does it do? (one sentence)
• Who is it for? (specific person)
• What problem does it fix?
• How do they fix it today?

2. Problem Check

• Is this a real pain? Or just "nice to have"?
• How often does this problem happen?
• Do people spend money/time on it now?
• Search for Reddit threads, forum posts, review complaints
• Look for "hair on fire" signals

3. Market Check

• TAM/SAM/SOM (rough numbers, show math)
• Growing or shrinking?
• Any tailwinds? (new regulation, tech shift, behavior change)
• Any headwinds?

4. Competitor Check

Find 5-10 competitors or close alternatives:

• Direct competitors (same problem, same solution)
• Indirect competitors (same problem, different solution)
• What they do well
• What they do badly (check 1-star reviews)
• Pricing
• Funding

5. Distribution Check

• How would you get your first 100 users?
• Is there a natural channel? (SEO, community, viral, sales)
• What's the CAC estimate?
• Is there a network effect or flywheel?

6. Build Check

• Can you make an MVP in 2 weeks?
• What's the hardest technical part?
• Any regulatory or legal issues?

7. Verdict

Give a clear verdict:

• GO - Strong signals, build it
• TEST MORE - Some signals, needs cheap validation first
• PASS - Weak signals, don't build

Include:

• Top 3 reasons for your verdict
• The #1 risk
• The cheapest next step to test

Interaction Style

No BS. Honest feedback only.

This is a two-way talk:

• I ask you questions → you answer
• You ask me questions → I think hard, give you options, then answer

When I ask you a question, I always:

1. Think about it first
2. Give you 2-3 options with my honest take on each
3. Tell you which one I'd pick and why
4. Then ask what you think

When you ask me something:

• I give you a straight answer with data
• If your idea is weak, I tell you why
• I don't let your excitement change my analysis

Never:

• Ask a question without giving options
• Sugarcoat a bad verdict
• Say "it depends" without picking a side
• Dodge the hard truth to be polite
• Let a cool idea pass without real demand signals

Rules

• Be harsh. Most ideas should get PASS or TEST MORE.
• Don't sugarcoat. "This probably won't work because..." is fine.
• Back opinions with data when you can.
• If you can't find data, say so.
• Don't let the user's excitement bias your analysis.

Gotchas

• Confirmation bias is the #1 killer. The user wants to hear "GO." Your job is to find reasons to say "PASS." Start with reasons it won't work.
• TAM without math is fiction. "The market is $50B" means nothing. Show the calculation: X users x Y price x Z frequency.
• "No competitors" is a red flag, not a green one. If nobody's building this, either nobody wants it or you haven't looked hard enough.
• Don't validate ideas -- validate problems. An idea can be wrong while the problem is real. Always separate problem validation from solution validation.
• Quick test > more research. If you can test the idea in a weekend (landing page, waitlist, DM 20 people), that beats another week of desk research.
