Validation Experiments & Hypotheses

Hypothesis #1: Problem Existence 🔴 Critical

We believe that AI engineers and prompt engineers

Will actively seek prompt management tools

If we provide a system to organize, version, test, and share prompts efficiently

We will know this is true when we see 60%+ of surveyed users confirm this as a top-3 need AND 5%+ landing page signup rate

Risk Level: 🔴 Critical (product fails if wrong)

Current Evidence: Forum discussions, search volume, competitor traction

Gaps: No direct user interviews yet

Pivot Triggers & Contingency Plans

Trigger #1: Problem Doesn't Exist

Signal: <40% of users confirm problem

Action: Interview users about their actual top problems, identify adjacent pain points

Pivot Options: Different problem in same audience, same problem in different audience

Trigger #2: Solution Doesn't Resonate

Signal: <50% satisfaction with prototype

Action: Deep-dive on what's missing, what's confusing, what's not valuable

Pivot Options: Simplify scope, change format, add human touch

Trigger #3: Won't Pay Enough

Signal: Acceptable price is <50% of target

Action: Find higher-value use case, different segment, or reduce costs

Pivot Options: Freemium with upsell, enterprise pivot, cost optimization

Trigger #4: Can't Acquire Efficiently

Signal: CAC >3x target in all channel tests

Action: Test organic/viral channels, reconsider pricing model

Pivot Options: Product-led growth, community-first, partnership distribution
