From Zero to Launch: A 4-Week MVP Development Timeline

Why 4 Weeks Is the MVP Sweet Spot

Most founders get MVP timelines completely wrong.

Too fast (1-2 weeks): You ship something broken that damages your reputation.
Too slow (3+ months): Competitors launch while you're still "perfecting" features nobody wants.

The sweet spot: 4 weeks gives you enough time to build something valuable but not enough time to overthink it.

After launching 50+ MVPs in exactly 28 days, here's our battle-tested timeline that turns ideas into revenue-generating products.

The 4-Week MVP Framework

Pre-Development (Week 0): Foundation Setting

Before writing a single line of code, nail these fundamentals:

Day -7 to -1: Planning Phase
- [ ] Define your core value proposition in one sentence
- [ ] Identify your primary user and their main problem
- [ ] List 15 potential features, then cut to 3 essential ones
- [ ] Choose your tech stack (we recommend Next.js + Supabase)
- [ ] Set up development environment and tools

Essential Questions:
1. What's the ONE thing your MVP must do perfectly?
2. What's the minimum viable user journey?
3. How will you measure success?

Red Flags to Avoid:
- Feature lists longer than one page
- Multiple user types in version 1
- Complex integrations that aren't core to value

Week 1: Foundation and Authentication

Goal: Build the skeleton that users can actually touch.

#### Day 1-2: Project Setup
- [ ] Initialize Next.js project with TypeScript
- [ ] Set up Supabase project and database
- [ ] Configure authentication (email/password + Google OAuth)
- [ ] Set up basic routing structure

Deliverable: Users can sign up, log in, and see a dashboard (even if empty).

#### Day 3-4: Database Schema
- [ ] Design core database tables
- [ ] Set up relationships between entities
- [ ] Implement Row Level Security policies

What to Build vs. What to Skip

Build in Week 1-4:

Essential Features Only:
- [ ] User authentication
- [ ] Core value-delivering functionality
- [ ] Basic payment processing (if revenue-generating)
- [ ] Mobile-responsive design
- [ ] Essential email notifications

Skip Until Post-Launch:

Nice-to-Have Features:
- [ ] Advanced user roles and permissions
- [ ] Complex reporting and analytics
- [ ] Social features and sharing
- [ ] Advanced integrations
- [ ] Extensive customization options
- [ ] Multiple payment methods
- [ ] Advanced mobile app features

The 70% Rule:

Ship when your MVP is 70% of your "perfect" vision. The remaining 30% should come from user feedback, not assumptions.

Common Timeline Killers (And How to Avoid Them)

Killer #1: Feature Creep

Symptom: "Just one more quick feature"
Time Cost: 2-3 weeks minimum
Solution: Lock features on day 1, no exceptions

Killer #2: Perfect Design Obsession

Symptom: Spending days tweaking colors and layouts
Time Cost: 1-2 weeks
Solution: Use a component library, not custom designs

Killer #3: Over-Engineering

Symptom: Building for 1M users when you have zero
Time Cost: 2-4 weeks
Solution: Build for 10x current scale, not 1000x

Killer #4: Integration Rabbit Holes

Symptom: "Let's add Slack integration while we're at it"
Time Cost: 1-3 weeks per integration
Solution: One integration at a time, post-launch

Killer #5: Testing Perfectionism

Symptom: 100% test coverage before launch
Time Cost: 2-3 weeks
Solution: Test core workflows manually, automate later

When 4 Weeks Isn't Enough

Some MVPs genuinely need more time. Extend the timeline if your MVP requires:

6-Week Timeline Justified For:

- Complex regulatory compliance (fintech, healthcare)
- Multiple user types with different workflows
- Heavy data processing or AI features
- Extensive third-party integrations

8-Week Timeline Justified For:

- Enterprise software with advanced security
- Multi-tenant SaaS with complex permissions
- Real-time collaboration features
- Custom algorithms or data processing

Red Flag: If you think you need 12+ weeks, you're probably not building an MVP.
