A useful SaaS product starts with a specific problem. Work through validation, scope, pricing, and launch before adding features nobody has asked for.
Phase 1: Validate Before You Build (Week 1–2)
Before writing a single line of code, validate your idea:
Validation Checklist:
- Search demand: Are people Googling for this solution?
- Competition: Who else solves this? What’s their weakness?
- Willingness to pay: Would 10 people pay for this?
- Your expertise: Can you actually build and maintain this?
Quick validation methods:
- Create a landing page and run $50 in Google Ads
- Post your concept on Reddit / relevant communities
- Talk to 10 potential customers directly
- Research competitor reviews for unmet needs
Phase 2: Choose Your Stack (Week 2–3)
| Decision | My Recommendation | Why |
|---|---|---|
| Backend | Django | Batteries included, Python ecosystem |
| Frontend | Tailwind CSS + HTMX | Productive, no JS framework needed |
| Database | PostgreSQL | Reliable, feature-rich, scalable |
| Auth | Django built-in | Secure, battle-tested |
| Payments | Stripe | Best developer experience |
| Hosting | Hetzner + Docker | Cost-effective, full control |
| CI/CD | GitHub Actions | Free for private repos |
| Resend or SendGrid | Transactional + marketing |
Phase 3: Build the MVP (Week 3–8)
MVP features (build ONLY these):
- User registration and login
- The ONE core feature that solves the problem
- Payment integration (Stripe)
- Basic settings/profile page
- Simple landing page that explains the product
What NOT to build in v1:
- Admin dashboard (Django Admin handles this)
- Social features
- Mobile app
- Complex analytics
- Custom email templates (use a service)
Phase 4: Launch & Get First Users (Week 8–10)
Launch channels:
- Product Hunt: Great for initial visibility
- Hacker News (Show HN): Developer audience
- Reddit: Find relevant subreddits
- Twitter/X: Build in public
- Blog posts: SEO for long-term traffic
Realistic Costs
| Item | DIY Cost | Outsourced Cost |
|---|---|---|
| Domain | $12/year | $12/year |
| Hosting (VPS) | $5–$20/month | $5–$20/month |
| SSL | Free (Let’s Encrypt) | Free |
| Email service | $0–$20/month | $0–$20/month |
| Payment processing | 2.9% + $0.30 per transaction | Same |
| Development | Your time | $2,500–$25,000 |
| Total first year | ~$300 + your time | $3,000–$26,000 |
Lessons from Building 3 SaaS Products
- Launch ugly, iterate fast — Perfection kills products
- Talk to users weekly — They know what they need
- Focus on SEO from day 1 — Free traffic compounds
- Charge from the start — Free users give bad feedback
- Keep the stack simple — Django + PostgreSQL handles 95% of use cases
