Idea Validation

Overview

Kill bad ideas fast, confirm good ones cheaply. Walk through every phase in order. Each phase has a kill-check — if the idea fails, document why and stop before wasting further time.

Step 1: Problem Definition

Everything starts here. A vague problem = a vague business.

Answer these four questions precisely:

1. Who — The exact person. Not "small businesses." Something like "freelance graphic designers juggling 3-8 client projects at once."
2. What — The specific painful moment. "They spend 4+ hours/week manually exporting deliverables and coordinating revision feedback via email chains."
3. Why it hurts — The real cost: time lost, revenue lost, stress, missed deadlines, damaged relationships. Quantify where possible.
4. What they do now — Their current workaround. This IS your real competition — not just competitor apps, but the status quo itself.

Kill check: Cannot answer all four concretely → problem is not well-defined. Do more discovery first.

Step 2: Demand Signal Gathering

Prove real people care. Do not rely on assumptions or polite friends.

Check 3+ of these signal sources:

Signal	Where	Positive Signal
Search volume	Google Trends, Ubersuggest free	Stable or growing volume on core problem keywords
Forum pain	Reddit, HN, Slack/Discord	Threads with 10+ comments describing this exact pain
Existing tool gaps	G2, App Store reviews	Tools solving adjacent problems with reviews citing the gap you'd fill
Job postings	LinkedIn, Indeed	Roles that exist only because this problem is expensive to solve manually
Social venting	Twitter/X search, LinkedIn	People publicly complaining about this unprompted

Kill check: Fewer than 3 positive signals → problem may not be painful enough. Pivot or kill.

Step 3: Solution Fit Check

Pressure-test whether your proposed solution actually solves the problem well enough to build a business on.

1. 10x rule: Is your solution 10x better (not 10%) than the current workaround in speed, cost, ease, or quality? Marginally better won't make people switch.
2. Workflow change audit: Map exactly what the user must change in their current routine. High friction = low adoption.
3. Solo-build feasibility: Can a working MVP be built by one person in weeks-to-a-few-months? If it needs a 10-person engineering team, that's a different company.
4. Unfair advantage: Why you specifically? Skills, industry access, data, network, credibility — something competitors can't easily replicate.

Kill check: Fail the 10x rule or have zero unfair advantage → move on.

Step 4: Customer Discovery (Talk to Humans)

10-15 conversations with real potential customers. Non-negotiable. No amount of desk research replaces this.

Finding people:

• Post in 2-3 relevant communities asking for 15-min feedback chats.
• DM matching personas on LinkedIn or Twitter.
• Offer a small incentive if needed (gift card, free future access).

Conversation flow (15-20 min):

1. CONTEXT (2 min)
   "Tell me about your work. Walk me through a typical week
    around [problem area]."
   → Listen only. Do NOT pitch or explain your idea.

2. PAIN EXPLORATION (5 min)
   "What's the most frustrating part of [workflow]?"
   "How often does that come up?"
   "What have you already tried to fix it?"
   "What's still missing?"
   → Ask "why" and "what happens when" repeatedly. Dig.

3. OUTCOME PROBING (3 min)
   "If a tool could [describe the outcome, not your feature set],
    how would that change things?"
   "What would that be worth — in time, money, stress?"
   → Let them quantify. Never suggest a number first.

4. WILLINGNESS TO PAY (2 min)
   "Would you pay for something like that? What range feels fair?"
   → Discount stated numbers by ~50% when planning.

5. WARM REFERRAL (1 min)
   "Know anyone else who hits this same wall? Mind if I reach out?"

Track across all conversations:

• % who described the problem without prompting (pain signal)
• % currently spending real money or time on workarounds (revenue signal)
• % with clear willingness to pay (demand signal)
• Features multiple people independently requested (product signal)
• Assumptions you held that conversations proved wrong (kill features early)

Kill check: Fewer than 60% confirm pain + willingness to pay → rework or kill.

Step 5: Riskiest Assumption Test (RAT)

One assumption, if wrong, kills everything. Find it. Test it in under 2 weeks and $200.

Common riskiest assumptions and cheap tests:

Assumption	Minimum Test	Pass Threshold
People will pay	Landing page + "pre-order" button. Drive 200 targeted visitors.	3-5% convert to payment/deposit
CAC is affordable	Run $100 targeted ad campaign. Measure cost-per-lead.	CPL < 20% of planned customer lifetime value
People will change workflow	Offer a manual version of the service to 5 people for free. See if they actually use it.	3+ out of 5 use it consistently
I can build it solo	Build the single hardest technical feature as a prototype first.	Working prototype in ≤ 2 weeks

Process:

1. State the assumption.
2. Define what "confirmed" looks like (a concrete, measurable number).
3. Design the cheapest possible test.
4. Set a hard deadline (max 2 weeks).
5. Run it. Record results with zero spin.

Kill check: RAT fails → idea in current form is not viable. Pivot the solution, the customer, or the model — or kill entirely.

Step 6: Go / No-Go Scorecard

Dimension	Score (1-5)	Weight
Problem severity & clarity	__	20%
Demand evidence gathered	__	15%
Customer discovery confirmation	__	20%
Solution fit (10x + feasibility)	__	15%
RAT result	__	20%
Your unfair advantage	__	10%

Weighted score = Σ (score × weight)

• 4.0–5.0 → GO. Move to MVP planning + business model canvas.
• 3.0–3.9 → CONDITIONAL GO. Resolve the weakest dimension with one more test round first.
• < 3.0 → NO-GO. Kill or fundamentally pivot. Write down lessons.

Idea Validation Mistakes to Avoid

• Not documenting findings in one place — insights scattered across notes, emails, and chats become useless. Keep one running "Idea Validation" doc from day one.
• Letting validation drag on indefinitely. Time-box the entire process to 2-3 weeks max. Validation paralysis is as fatal as skipping it entirely.
• Testing one idea in isolation. Run 2-3 ideas in parallel when possible — the comparison sharpens judgment and reveals which assumptions you're making about all of them.
• Confusing polite interest with real demand. Friends and colleagues will say nice things. Pay-or-commit signals from strangers are the only ones that count.
• Skipping the kill checks. Each phase has a kill check for a reason. Ignoring a failed check and pressing forward wastes weeks or months on a dead-end idea.
