Validation Experiments & Hypotheses

Hypothesis Framework

Hypothesis #1: Problem Existence 🔴 Critical

We believe that solo founders and bootstrapped entrepreneurs will actively seek viability analysis tools if they are trying to validate a new product idea. We will know this is true when we see 60%+ of surveyed founders confirm this is a top-3 pain point AND 5%+ landing page signup rate.

Risk Level: 🔴 Critical (product fails if wrong)

Current Evidence: Supporting: Forum discussions, search volume, competitor traction. Contradicting: None identified. Gaps: No direct user interviews yet.

Experiment Design:

Method: Customer discovery interviews + landing page test

Sample Size: 20 interviews, 1,000 landing page visitors

Duration: 2 weeks

Cost: $500 (ads) + 20 hours (interviews)

Success Metrics:
Metric Fail Minimum Success Home Run
Problem confirmation rate <40% 40-60% 60-80% >80%
Landing page signup <2% 2-5% 5-10% >10%

Next Steps if Validated: Proceed to solution validation. Next Steps if Invalidated: Pivot to adjacent problem or exit.

Hypothesis #2: Solution Fit 🔴 Critical

We believe that founders seeking validation will use an AI-powered analysis tool instead of manual research if we deliver comprehensive, actionable reports in minutes instead of weeks. We will know this is true when we see 70%+ of prototype users rate the output as "useful" or "very useful".

Risk Level: 🔴 Critical

Current Evidence: Supporting: Initial feedback from prototypes. Contradicting: User skepticism about AI accuracy. Gaps: No formalized testing yet.

Experiment Design:

Method: Prototype testing with early adopters.

Sample Size: 10 prototype users.

Duration: 2 weeks.

Cost: $200 (incentives).

Success Metrics:
Metric Fail Minimum Success Home Run
User satisfaction rating <6/10 6-7/10 7-8/10 >8/10

Next Steps if Validated: Proceed to pricing validation. Next Steps if Invalidated: Reassess feature set.

Hypothesis #3: Willingness to Pay 🔴 Critical

We believe that bootstrapped founders will pay $49-$99 for a single viability analysis if we provide investor-grade output that saves 20+ hours of research. We will know this is true when we see 10+ pre-orders at target price point.

Risk Level: 🔴 Critical

Current Evidence: Supporting: Pricing benchmarks from competitors. Contradicting: User hesitance for upfront payments. Gaps: No pre-order testing yet.

Experiment Design:

Method: Pricing survey with pre-order option.

Sample Size: 100 target users.

Duration: 2 weeks.

Cost: $300 (survey tools).

Success Metrics:
Metric Fail Minimum Success Home Run
Pre-orders collected <5 5-10 10-20 >20

Next Steps if Validated: Finalize pricing model. Next Steps if Invalidated: Reevaluate pricing strategy.

Experiment Catalog

Experiment #1: Problem Discovery Interviews

Hypothesis Tested: #1 (Problem Existence)

Method: Semi-structured interviews with target users

Setup:

  • Recruit 20-30 founders via LinkedIn, Twitter, Reddit
  • Offer $50 gift card incentive
  • Schedule 45-60 minute video calls
  • Use interview guide (see User Research section)
  • Record and transcribe conversations

Metrics:

  • % confirming problem as top-3 pain
  • Frequency of problem occurrence
  • Current spend on alternatives (time/money)
  • Quotes indicating severity

Timeline: 2 weeks (parallel recruitment and interviews)

Cost: $1,000-$1,500 (incentives)

Success Criteria:

  • ✅ Pass: 60%+ confirm problem as significant
  • ⚠️ Re-evaluate: 40-60% confirmation
  • ❌ Fail: <40% confirmation

Owner: [Assign responsibility]

Experiment #2: Landing Page Smoke Test

Hypothesis Tested: #1 (Problem Existence) + #2 (Solution Interest)

Method: Landing page with waitlist signup

Setup:

  • Create single landing page (Carrd, Unbounce, or custom)
  • Write compelling headline and value proposition
  • Add waitlist email capture form
  • Drive traffic via Google/Facebook ads
  • Track conversions with analytics

Variants to Test:

  • Headline A: "Validate your startup idea in 24 hours"
  • Headline B: "AI replaces your $50K business consultant"
  • Headline C: "Stop building products nobody wants"

Metrics:

  • Traffic volume (target: 1,000+ visitors)
  • Signup rate by variant
  • Time on page
  • Scroll depth

Timeline: 2 weeks (1 week setup, 1 week traffic)

Cost: $500-$1,000 (ads)

Success Criteria:

  • ✅ Pass: >5% signup rate
  • ⚠️ Re-evaluate: 2-5% signup rate
  • ❌ Fail: <2% signup rate

Experiment #3: Wizard of Oz MVP

Hypothesis Tested: #2 (Solution Fit) + #3 (Willingness to Pay)

Method: Manually deliver the service using AI + human judgment

Setup:

  • Accept project specs via Google Form
  • Generate analysis using Claude/GPT with custom prompts
  • Polish and format output manually
  • Deliver via email with feedback request
  • Offer to pay after receiving output

Metrics:

  • Time to deliver (target: <24 hours)
  • User satisfaction (1-10 rating)
  • NPS score
  • % willing to pay after seeing output
  • Actual payment conversion

Timeline: 4 weeks (10-20 users)

Cost: Time only (10-20 hours of effort)

Success Criteria:

  • ✅ Pass: 8+/10 avg satisfaction, 50%+ would pay
  • ⚠️ Re-evaluate: 6-8/10 satisfaction
  • ❌ Fail: <6/10 satisfaction, <30% would pay
