MVP Launcher

Framework for rapid MVP validation and launch using proven startup methodologies from Y Combinator, lean startup, and first-principles thinking.

Core Workflow

1. Problem-Solution Validation

Ask the forcing questions:

  • What specific problem are you solving? (Not a solution in disguise)
  • Who has this problem urgently enough to pay?
  • How are they solving it now? (Current alternatives = market validation)
  • Why will they switch to your solution?

Output: One-sentence value proposition that passes the "mom test"

2. Market Sizing (Быстрая оценка)

Use scripts/market_sizer.py for TAM/SAM/SOM calculation:

python scripts/market_sizer.py --total-market 1000000 --addressable-percent 10 --obtainable-percent 5

Reality checks:

  • TAM > $1B = maybe real market
  • SAM > $100M = venture-scale potential
  • SOM (first year) = be honest, usually <1% of SAM

3. MVP Scope Definition

Принцип: Smallest thing that proves value hypothesis

Use assets/mvp_canvas.md template to define:

  • Core value proposition (1 sentence)
  • Primary user action (1 action)
  • Success metric (1 number)
  • Time to first value (<5 minutes ideal)

Anti-pattern: "But we also need..." → NO. Ship, measure, iterate.

4. Monetization Strategy

See references/monetization-models.md for quick selection guide.

Key decisions:

  • Pricing model: subscription / usage-based / transaction / freemium
  • Price point: value-based (not cost-plus)
  • Payment psychology: annual discounts, tiered pricing, anchor pricing

Forcing function: If they won't pay $X for this, the problem isn't urgent enough.

5. Unit Economics

Use scripts/unit_economics.py for rapid calculation:

python scripts/unit_economics.py --ltv 1200 --cac 400 --churn-rate 5

Minimum viability:

  • LTV:CAC ratio ≥ 3:1
  • CAC payback ≤ 12 months
  • Monthly churn ≤ 5% (for SaaS)

If numbers don't work at scale, pivot or kill the idea.

6. Build & Launch Strategy

Week 1-2: Core feature + payment Week 3: First 10 paying customers (manual sales, no automation yet) Week 4: Measure, learn, decide: iterate / pivot / kill

Tech principles:

  • No-code/low-code first (n8n, Airtable, Webflow)
  • Manual processes behind automated facade
  • Don't build what you can integrate
  • PostgreSQL + Python API = enough for 100k users

7. Metrics Framework

See references/metrics-framework.md for stage-specific KPIs.

MVP stage - track only:

  • Activation rate (signup → first value)
  • Retention (D1, D7, D30)
  • Revenue per user
  • NPS or qualitative feedback

Ignore: total users, page views, social followers (vanity metrics)

8. Go-to-Market

Before product-market fit:

  • Do things that don't scale (Paul Graham)
  • Talk to users every day
  • Manual sales → learn messaging
  • Early adopters ≠ mainstream market

Channel testing sequence:

  1. Direct outreach (LinkedIn, email, communities)
  2. Content/SEO (if long sales cycle)
  3. Paid ads (only after LTV:CAC proven)
  4. Partnerships/integrations

Decision Points

When to iterate:

  • Users sign up but don't activate → onboarding problem
  • Users try once then churn → not enough value
  • Good engagement, won't pay → wrong audience or positioning

When to pivot:

  • No organic growth after 3 months of trying
  • LTV:CAC fundamentally broken
  • Users love it, but market too small

When to kill:

  • No one cares (not even early adopters)
  • You've stopped believing in it
  • Better opportunity identified

Reference Materials

Load as needed:

  • Monetization models: See references/monetization-models.md
  • Metrics frameworks: See references/metrics-framework.md
  • YC startup playbook: See references/yc-playbook.md

Templates

  • MVP Canvas: assets/mvp_canvas.md - One-page planning template
  • Unit economics sheet: Generate via scripts
  • Weekly progress template: In assets/

Anti-Patterns to Avoid

  • Building for 6 months before talking to users
  • Perfecting features instead of testing core hypothesis
  • Raising money before product-market fit
  • Hiring before proving the model works
  • Optimizing conversion before understanding why users stay
  • "If we build it, they will come"
