Step 1: Validate Your Idea
Before writing a single line of code, confirm that people actually have the problem you're solving—and that they'll pay for a solution.
42% of startups fail because there's no market need. Validation helps you avoid building something nobody wants.
How to Validate:
- Customer Interviews: Talk to 20+ potential customers. Ask about their problems, not your solution.
- Landing Page Test: Create a simple page, drive traffic, measure signups. 10%+ conversion = strong interest.
- Pre-sales: The ultimate validation—get people to pay before you build.
The best validation is money changing hands. If people won't pay $50 for early access, they probably won't pay $50/month for the finished product.
Step 2: Define Your Target User
"Everyone" is not a target market. The more specific your target user, the easier it is to build something they love.
Answer these questions:
- Who are they? Job title, company size
- What problem do they have? Be specific
- How are they solving it now? Current alternatives
- Why is current solution inadequate? The gap you fill
Facebook started with Harvard students only. Uber started in San Francisco only. Amazon started with books only. Start narrow, then expand.
Step 3: Map the Core User Journey
What's the simplest path from "user has problem" to "problem solved"? Every step that isn't on this path is a candidate for cutting.
- Signup/Onboarding: What's the minimum info needed?
- First Value: What's the "aha moment"? Get users here fast.
- Core Action: The main thing users do repeatedly.
- Success: User's problem is solved.
If your MVP could only do one thing, what would it be? That's your core action. Everything else is secondary.
Step 4: List Features (Then Cut 80%)
This is where most founders go wrong. They add "just one more feature" until the MVP becomes a full product.
✅ Must Have (Include)
- Core value proposition feature
- User authentication (if needed)
- Basic onboarding flow
- One way to complete main task
- Mobile-responsive design
❌ Nice to Have (Cut)
- Social login options
- Advanced settings
- Multiple payment methods
- Admin dashboard
- Email notifications
"If you're not embarrassed by the first version of your product, you've launched too late."

Step 5: Choose Your Tech Stack
For MVPs, choose boring, proven technology. This isn't the time for experiments.
Also recommended: Stripe for payments, Clerk/Auth0 for auth, Vercel/Railway for hosting.

Step 6: Build the MVP
Now it's time to build. Focus on functionality over polish.
🔨 Build Yourself If...
- You're a technical founder
- You have 2-3 months to spare
- Budget is extremely limited
🤝 Hire Help If...
- You're non-technical
- Speed is critical (30 days)
- You have $5K+ budget
Step 7: Launch and Get Feedback
Your MVP is ready. Now launch and start learning from real users.
Where to Launch:
- Product Hunt: Great for B2B/B2C products
- Hacker News: Technical audience
- Reddit: Find subreddits where your users hang out
- Direct Outreach: Your first 10 users should come from direct contact
Your first 10 users are gold. Talk to every single one. Understand why they signed up, what they're trying to do, and what's blocking them.
