How I helped a founder launch in 6 weeks (and what you can learn from it)

The Story

January 2025. A founder calls me. He has seed funding, an idea, and 6 weeks to prove it works. His question: "Can you build this?"

6 weeks later: Live product, 50+ users, first payments coming in.

This is how we did it, and what other founders can learn from it.

The Situation

The founder: Sarah (28), healthtech startup The idea: AI-powered coaching app for PMDD patients Budget: €35k Deadline: 6 weeks (investor pitch) Goal: Validate if the concept works before requesting more funding

The problem: Traditional agencies said "3-4 months minimum". Sarah had 6 weeks.

Why This Works For Founders

1. Founders Have Urgency

    Sarah had no time for:
  • 3 months discovery phase
  • Endless meetings
  • Perfect design for day 1
    She had time for:
  • MVP that works
  • Testing with real users
  • Iterating based on feedback
This is exactly what founders need. Not perfect, but working.

2. MVP Thinking = Speed

    We focused on:
  • ✅ Core functionality (coaching content + AI chat)
  • ✅ User accounts (so they can test)
  • ✅ Payments (so they can validate)
  • ❌ Premium features (later)
  • ❌ Complex analytics (later)
  • ❌ Perfect design (later)
80% features, 100% working. This is MVP thinking.

3. Iterative Work = Faster Learning

Week 1-2: Build core features Week 3: Test with 5 beta users Week 4: Process feedback Week 5: Iterate Week 6: Launch with first paying users

Every week we learned something new. Every week we improved.

Our Approach

Week 1: Discovery + Start Building

Day 1-2: Conversation about goals, features, and what's really important Day 3-4: Design sketches (Figma) Day 5-7: Start building (Next.js + Supabase)

Important: We didn't wait until everything was perfect. We started building.

Week 2-3: Core Features

    What we built:
  • User authentication (Supabase Auth)
  • Content management (coaching modules)
  • AI chat (OpenAI API)
  • Basic dashboard
    What we DIDN'T build:
  • Complex analytics
  • Premium features
  • Perfect UI/UX
Focus: Working product, not perfect product.

Week 4: Beta Testing

    5 beta users tested the product. We collected feedback:
  • "AI chat works well"
  • "Content is clear"
  • "Dashboard is simple but effective"
Most important feedback: "I would pay for this if it works."

Week 5: Iterate

    Based on feedback:
  • AI responses improved
  • Content structure adjusted
  • Dashboard usability improved
No big changes. Small improvements that make the difference.

Week 6: Launch

    Went live with:
  • Working product
  • 5 beta users already using it
  • Payments integrated (Stripe)
  • First paying users within 48 hours
Result: 50+ users in first week, first payments, successful investor pitch.

What Other Founders Can Learn

1. Speed > Perfection

For founders: You don't have time for perfect. You have time for working.

    Focus on:
  • Core features that add value
  • Testing with real users
  • Iterating based on feedback
    Not on:
  • Perfect design
  • All features
  • Complex systems

2. MVP = Minimum Viable Product

Viable = it works Minimum = only what's needed
    Sarah's MVP:
  • ✅ AI chat that works
  • ✅ Content that adds value
  • ✅ Payments that work
  • ❌ Premium features (later)
  • ❌ Complex analytics (later)
This is enough to validate.

3. Iterative = Faster Learning

    Traditional approach:
  • 3 months building
  • Then testing
  • Then rebuilding everything
    Our approach:
  • 2 weeks building
  • Testing
  • Iterating
  • Testing
  • Iterating
Every iteration teaches you something new.

4. Founders Have Different Needs

    Traditional agencies think:
  • "We need to make everything perfect"
  • "We need to cover all edge cases"
  • "We need to build complex systems"
    Founders think:
  • "I need to validate quickly"
  • "I need to test with real users"
  • "I need to prove it works"
This is why speed matters for founders.

The Numbers

    Timeline: 6 weeks Budget: €35k Features: Core MVP Result:
  • 50+ users in first week
  • First payments within 48 hours
  • Successful investor pitch
  • Product-market fit proven
ROI: Within 2 months she had enough users to continue.

What If You Want This Too?

    For founders with:
  • Seed/angel funding
  • 6-12 week deadline
  • Product idea that needs testing
    This is what we do:
  • Week 1: Discovery + start building
  • Week 2-4: Build core features
  • Week 5: Beta testing
  • Week 6: Launch
Budget: €15k-€50k (depending on scope) Timeline: 4-12 weeks Focus: Working product, not perfect product

The Most Important Lesson

For founders: Speed is more important than perfection.

For agencies: Founders have different needs than corporate clients.

For everyone: MVP thinking = faster learning, faster validation, faster growth.
