| $20K MRR | Varies | Zero employees, zero advertising |
| $83K | 9 months | Single product |
Phase 1: Discovery (Weeks 1–2)
- Find a real problem by analyzing complaints in forums and social media
- Validate demand with a landing page and AI stress-testing
- Check legal risks with a trademark search
Phase 2: Build (Weeks 3–6) 4. Set up your chosen stack (use whatever you're comfortable with) 5. Use vibe coding with discipline: spec first, Plan Mode, Git commits, manual review 6. Implement security from day one 7. Ship within 30 days
Phase 3: Launch and Grow (Months 2–6) 8. Get first 10 paying customers manually 9. Build organic distribution: SEO, communities, referral/affiliate programs 10. Track MRR growth, churn, LTV:CAC—ignore vanity metrics 11. Iterate based on real usage data
Phase 4: Scale and Protect (Month 6+) 12. Delay hiring—automate first 13. Protect: trademarks, ToS, DDoS protection 14. Plan for exit: clean financials, documented processes 15. Protect your well-being—the goal is freedom
- Generic productivity tools
- "AI-powered" versions of existing categories
- Products that require more than one sentence to explain
AI-generated code has a ~45% vulnerability rate. Always:
- Review security-critical code yourself
- Use AI for UI and boilerplate only
- Keep core business logic human-verified
- Implement security from day one
- Building has become easy; distribution remains the bottleneck
- Paid ads don't work for early-stage solo SaaS ($50-100 per lead)
- The most successful founders use zero-paid advertising
- 80% of time should go to distribution at $0 MRR
| Metric | Survival | Strong | Elite |
|---|---|---|---|
| MRR Growth | >5% MoM | >10% MoM | >15% MoM |
| Churn Rate | <5%/mo | <3%/mo | <1.5%/mo |
| LTV:CAC Ratio | >1:1 | >3:1 | >5:1 |
| Payback Period | <18 months | <12 months | <6 months |
| Gross Margin | >60% | >75% | >85% |
- Starting low hurts conversions: raising from $19 to $29/mo doubled conversion rate
- People will pay more than you think—price based on value delivered
- Never compete on price
- Entry tier: $9–$29/mo (below corporate card thresholds)
This handbook is based on real stories from:
- r/SaaS, r/micro_saas, r/Solopreneur communities
- Twitter/X threads from founders like Greg Isenberg
- Real case studies: $300K failures, $83K successes, everything in between
The bottom line: At $0, your job isn't to be a developer—it's to be a salesperson who can code.
