From Idea to Deployed MVP in 2 Weeks: A Technical Breakdown

Two weeks sounds impossibly fast for a full-stack SaaS product. But I've done it — and the key isn't working harder. It's being ruthless about what you build and what you skip.

This is the exact playbook I use.

Week 1: Infrastructure + Core Loop

Day 1-2: Project scaffold and auth

Don't start with the "interesting" features. Start with the boring infrastructure that everything else depends on.

next create-next-app@latest  (App Router, TypeScript, Tailwind)
→ Clerk or NextAuth for authentication
→ Prisma + PlanetScale (or Supabase) for the database
→ Vercel for deployment (do this on day 1, not day 14)

Why deploy on day 1? Because deployment surprises kill projects. Get it live immediately, even if it's just a login page.

Day 3-4: Core data model

This is the most important architectural decision you'll make. Get the data model wrong and everything else is expensive to fix.

Rules:

• Model the core entity first (the thing your product is fundamentally about)
• Add created_at, updated_at, userId on everything
• Keep it flat — no premature normalisation
• Plan for soft deletes from the start (add deletedAt)

Day 5-7: The one core loop

An MVP doesn't need features. It needs one loop that works end-to-end:

• User can create a [thing]
• User can see their [things]
• User can do the core action on a [thing]

If your product is a project management tool, the core loop is: create project → add tasks → mark complete. Everything else — comments, integrations, team members, notifications — is deferred.

Week 2: Polish, Payments, Launch

Day 8-9: Payments

Stripe is the only correct answer. Specifically:

// Use Stripe Checkout + webhooks
// Never build your own payment form
// Add Stripe Customer Portal for subscription management

Set up:

1. Stripe Checkout for subscription creation
2. Webhook handler for checkout.session.completed and invoice.paid
3. Store stripeCustomerId and subscriptionStatus on your user

Don't build billing logic yourself. Don't build a custom payment form. Don't defer payments until post-launch. Payments are infrastructure — do them early.

Day 10-11: The 3 pages that matter

Every SaaS needs exactly these:

1. Landing page — what it does, who it's for, one CTA
2. Dashboard — the logged-in home, your core loop
3. Pricing page — simple, 2-3 tiers maximum

That's it. No blog, no docs, no changelog, no team page. Those are post-traction.

Day 12-13: Error handling and loading states

This is the difference between "technically works" and "feels like a real product." Every async operation needs:

• A loading state (skeleton or spinner)
• An error state (clear message + recovery action)
• An empty state (what users see before they have data)

These take time but they're the things users notice. A blank screen with no explanation kills trust.

Day 14: Launch prep

• Set up Plausible or PostHog (analytics, free tier)
• Add basic error monitoring (Sentry, free tier)
• Write 5 cold DMs to your target users
• Post on Twitter/X, Hacker News, or the relevant community

What I Always Skip in Week 1-2

• Team/collaboration features — build for solo users first
• API/webhooks — nobody is asking for this yet
• Advanced search/filtering — YAGNI
• Email notifications — use Resend but only for critical transactional emails
• Mobile app — responsive web is fine for MVP
• Internationalisation — get English right first
• Dark mode — seriously, defer it

The Stack I Default To

For a solo founder or 2-person team shipping in 2 weeks:

The Mindset Shift

The hardest part of 2-week MVPs isn't technical — it's the discipline to say no to yourself.

Every day you'll have ideas for features that seem obviously important. Write them down. Don't build them. The question isn't "is this a good idea?" It's "will users churn without this in week 1?"

Ship ugly. Ship incomplete. Get someone to pay for it. Then iterate.
