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
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)
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 usersEvery 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
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"
Week 5: Iterate
- Based on feedback:
- AI responses improved
- Content structure adjusted
- Dashboard usability improved
Week 6: Launch
- Went live with:
- Working product
- 5 beta users already using it
- Payments integrated (Stripe)
- First paying users within 48 hours
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)
3. Iterative = Faster Learning
- Traditional approach:
- 3 months building
- Then testing
- Then rebuilding everything
- Our approach:
- 2 weeks building
- Testing
- Iterating
- Testing
- Iterating
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"
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
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
The Most Important Lesson
