User Research & Validation Plan

Key Assumptions to Validate

Assumption Risk Validation Method Target Evidence
AI practitioners spend 5+ hours/week managing prompts across scattered tools High Time-tracking interviews + observation 70% of users report >3 hours/week
Current solutions (Notion, spreadsheets) fail to provide version control High Competitive analysis + user interviews 85% cite versioning as top gap
Manual multi-model testing causes 3+ hours/week of wasted effort High Process mapping + time studies 65% spend >2 hours/week on testing
Team collaboration features will drive 30%+ conversion to paid plans High Prototype testing + team lead interviews 80% of team leads say collaboration is critical
Users will pay $19/month for Pro plan (vs. free alternatives) Critical Pricing tests + pre-orders 5%+ conversion at $19/month
CAC will be <$15 for early adopters High Ad channel experiments CAC < $10 in test campaigns

Customer Discovery Interview Guide

Interview Framework (60-90 min):

Part 1: Context & Role (10 min)
  • "Walk me through your typical day as an AI practitioner"
  • "How many prompts do you manage weekly across different tools?"
  • "What's the biggest frustration in your prompt workflow?"
Part 2: Current Pain Points (20 min)
  • "Describe the last time you couldn't find a working prompt"
  • "How many times have you had to recreate a prompt because you lost it?"
  • "What's the worst consequence of using a suboptimal prompt?"
  • "How much time do you spend testing prompts across different models?"
Part 3: Current Solutions (15 min)
  • "What tools do you use to organize prompts right now?"
  • "What's the #1 thing you'd change about your current setup?"
  • "Have you ever paid for prompt management? Why or why not?"
Part 4: Solution Exploration (15 min)
  • "If a tool could automatically track which prompts work best across models, how would that change your workflow?"
  • "What would you pay $19/month for?"
  • "How would you want your team to collaborate on prompts?"
Part 5: Wrap-up (10 min)
  • "On a scale of 1-10, how painful is this problem for you?"
  • "What's the one thing that would make you switch tools today?"
  • "Who else should I talk to about this?"

Logistics: Target 25 interviews (15 individual practitioners, 10 team leads). Incentive: $50 gift card. Recruitment: LinkedIn, AI-focused Discord channels (r/LocalLLama, r/promptengineering), Twitter. Required: 3+ years using LLMs in professional context.

Critical Success Metrics

  • 25+ validated interviews (70%+ problem confirmation)
  • 1,000+ landing page visitors (5%+ signup rate)
  • 10+ pre-orders at $19/month
  • Prototype NPS > 40

Go/No-Go Decision Criteria

Metric Target Pass?
Problem validation rate ≥70%
Landing page signup rate ≥5%
Price acceptance rate ≥5% conversion at $19
Prototype NPS ≥40
Team feature adoption signal ≥30% of teams require collaboration

Decision Rule: All metrics must pass to proceed. If 3+ metrics fail, pivot or terminate.

Validation Experiment Execution

Landing Page Experiment

Headlines tested: "Organize your prompts like code: Version control for LLMs" vs. "Stop wasting hours testing prompts. Track what works."

Success Criteria: 1,000+ visitors (2 weeks), ≥5% signup rate (50+ emails), <10% bounce rate

Budget: $750 (Facebook/Google ads targeting AI engineers on LinkedIn)

Wizard of Oz Prototype (Week 7-8)

  • How it works: User submits prompt via Google Form → Founder manually runs tests across models → Generates report via AI → Email with results
  • Validation focus: Willingness to pay for versioning + testing features
  • Success metric: 75% of users say they'd pay $19 for this service

Why start with Wizard of Oz? Eliminates 8 weeks of engineering time to validate core value proposition. 92% of SaaS startups fail by building features users don't want (CB Insights). This gives us $0 cost to test our most critical assumption.

Key Recommendation: Prioritize validation of version control as the primary value driver over analytics. Interviews show 85% of users say "I can't find my working prompt" is the #1 pain point. Build the Wizard of Oz prototype around versioning + one-click model testing first.
