Why 8 Weeks Is the Right Target for an MVP
Most agencies quote 4–6 months. Most startups want it in 2 weeks. Neither is realistic for a useful product. Here's why 8 weeks hits the sweet spot:
- Long enough to build something real users can actually use
- Short enough to test market assumptions before you've spent too much
- Forces you to cut features that don't serve the core use case
- Maintains team momentum — 6+ month timelines breed scope creep and pivots
Phase 1: Discovery (Week 1)
Scope, Spec, and User Flows
We run a structured discovery sprint: 3 hours of business requirements, 3 hours of user flow mapping, 2 hours of technical architecture, 2 hours of spec documentation. Output: a 15–25 page spec document that defines every screen, API endpoint, and user role. This is the contract that prevents scope creep.
What we produce:
- Feature list (must-have vs. nice-to-have, explicitly separated)
- User role matrix (who can do what)
- API endpoint map (every route and its parameters)
- Data model (tables, relationships, constraints)
- Third-party integration list (payments, auth, notifications)
Lesson learned: In our first 5 projects, we skipped formal spec documentation. Three of them overran by 4+ weeks because the client and we had different mental models of "what the app does." Every extra week in discovery saves two weeks in development.
Phase 2: Design (Weeks 2–3)
UI Prototype Before Any Code
Every screen in the spec gets a Figma prototype. We use a design system (either Shadcn-based or custom for premium projects) for consistency. Client signs off on the prototype before we write a single line of code. This is non-negotiable.
- Mobile-first layout for all screens
- Interactive Figma prototype (clickable flows, not static images)
- 2 rounds of revision included
- Design tokens established for colors, typography, spacing
Lesson learned: Clients often discover what they really want when they see a prototype. It's much cheaper to change a Figma file than to refactor code. We had one client change their entire dashboard layout after seeing the prototype — took 4 hours to update. Would have been 3 weeks of rework in code.
Phase 3: Build (Weeks 4–8)
Clean Code With Tests and CI/CD
Development starts with the CI/CD pipeline — before the first feature. Every commit runs ESLint, type checking, and unit tests. We demo working software every Friday. You always know exactly where your project stands.
Our development order for a typical web app:
- Week 4: Database schema, API skeleton, authentication
- Week 5: Core feature 1 (the main user action of your app)
- Week 6: Core feature 2 + integrations (payments, notifications)
- Week 7: Admin dashboard + secondary features
- Week 8: Testing, performance optimization, security review, production deployment
Our tech stack default: Next.js 15 + FastAPI + PostgreSQL + Redis. We deviate when there's a good reason (mobile: React Native; simple apps: Supabase).
Phase 4: Launch & Support (Week 9+)
Production Launch + Monitoring
Deployment to Google Cloud Run (or Vercel for frontend-heavy apps). We configure monitoring, set up alerts, and hand over the codebase with complete documentation. 3 months of post-launch support is included in every contract.
- Cloud Run deployment with auto-scaling
- Domain + SSL configuration
- Uptime monitoring + alerting
- Full code handover with README and deployment docs
- 3-month support (bug fixes, security patches, small changes)
What Makes the 8-Week Timeline Slip
In 15% of our projects, we go 1–2 weeks over. Here's what causes it:
- Slow client feedback — if design approvals take a week instead of 2 days, it cascades. We now set 48-hour SLAs for client reviews
- Changing requirements during build — any change post-spec is logged, scoped, and either deferred or quoted separately
- Third-party API surprises — payment gateways and SMS providers have rate limits, sandbox bugs, and documentation gaps. We now build 3 buffer days for integrations
- Performance issues discovered late — we now run load testing in week 7, not after launch
