💡 PRO TIPS & EXAMPLES

Calendly started with a simple idea: scheduling meetings shouldn't be painful. Their MVP was a basic calendar integration that solved one problem exceptionally well. They didn't build team scheduling, custom branding, or analytics until they had thousands of users. Focus on one core problem first.

  • Frontend: Next.js (React) with Tailwind CSS
  • Backend: Supabase or Firebase for quick setup
  • Database: PostgreSQL (Supabase) or MongoDB
  • Authentication: Clerk or Supabase Auth
  • Payments: Stripe or Paddle
  • Hosting: Vercel or Railway
  • Email: Resend or Postmark

The biggest killer of SaaS projects is adding "just one more feature" before launch. Your MVP should solve the core problem and nothing more. Additional features should come from user requests, not your imagination.

⚠️ COMMON MISTAKES TO AVOID

1. Building in stealth mode: Get feedback early and often. Don't wait until "it's perfect."

2. Over-engineering: Use simple solutions that work. You can refactor later.

3. Ignoring pricing: Decide on pricing before you build. It affects your architecture.

4. Skipping analytics: You can't improve what you don't measure.

5. Trying to please everyone: Focus on a specific niche first.

6. Underestimating marketing: Building is only half the battle. You need users.

7. Not having a support plan: Be ready to help your first customers.

📊 KEY METRICS TO TRACK

  • Waitlist signups (goal: 100+)
  • Feedback quality (specific vs. vague)
  • Problem-solution fit score

  • Activation rate (% who complete onboarding)
  • Conversion rate (% who become paying customers)
  • Churn rate (% who cancel in first month)
  • Monthly recurring revenue (MRR)
  • Customer acquisition cost (CAC)
  • Customer lifetime value (LTV)

  • LTV:CAC ratio (aim for 3:1 or higher)
  • Activation:Conversion ratio (identify drop-off points)
  • Support tickets per user (measure product clarity)
