Cross-Domain Patterns​

Business Models​

  • Freemium SaaS: Most developer tools, EdTech B2C
  • Open-source + Premium: Postman alternative
  • Dual-sided marketplace: Coding tests (B2C free, B2B paid)
  • Usage-based pricing: Alternative to per-seat
  • Pay-as-you-go: CodeRabbit alternative

GTM Strategies​

  • Developer tools: Open-source → Product Hunt → HN → GitHub stars
  • EdTech B2C: Free tier → viral → paid conversion
  • B2B SaaS: Start B2C, pivot to B2B once traction

Tech Stacks​

  • Common: LLMs (GPT-4, Claude), cloud infrastructure, modern web frameworks
  • DevTools: Native apps (Tauri), browser extensions, VS Code extensions
  • AI Assessment: Voice AI, code sandboxing, LLM evaluation

Solo Founder Suitability​

Best fits (⭐⭐⭐⭐⭐):

  1. Postman Alternative - Pure software, viral growth potential
  2. AI Mock Interviews - High value, clear monetization
  3. AI Subjective Grading - Fast to build, clear pain point

Good fits (⭐⭐⭐⭐): 4. AI Coding Tests - Larger scope but big market 5. One-Click GitHub Demo - Technical challenge, infrastructure costs 6. Git/Docker Tool - Smaller market, needs validation

Requires more validation (⭐⭐⭐): 7. Government Tracker - Monetization unclear 8. Fact-Checker Bot - Platform risk, moderation issues

Raw Research & Analysis​

Comprehensive Research Documents:

To Be Created:

  • Market sizing for each domain
  • Competitor deep dives
  • Technical architecture plans
  • Financial projections
  • GTM playbooks

Next Actions​

Immediate (This Week)​

  1. Choose top idea (Postman Alternative or AI Mock Interviews)
  2. User interviews (10-20 target users)
  3. Competitor analysis deep dive
  4. MVP feature prioritization
  5. Technical spike (test core technology)

Short-term (Month 1)​

  1. Build MVP
  2. Beta testing with 10 users
  3. Landing page + waitlist
  4. Pricing research

Medium-term (Months 2-3)​

  1. Public launch (Product Hunt, HN, Reddit)
  2. Gather feedback, iterate
  3. Add monetization
  4. Content marketing

Research Methodology​

How this wiki works:

  • Human responsibility: Curate sources, direct analysis, prioritize ideas
  • LLM responsibility: Cross-referencing, synthesis, maintaining consistency
  • Process: Ingest research → Update 10-15 pages → Link across domains → Track in log

When adding new research:

  1. Create raw research file in
  2. Extract into relevant startup idea pages
  3. Create competitor/market analysis pages as needed
  4. Update this index
  5. Log activity in log.md

Original Idea Sources​

All ideas sourced from:

Research Log​

See log.md for chronological activity log.

Latest activities:

  • 2026-05-02: Initial research on software-focused solo founder opportunities
  • 2026-05-02: Deep dive into AI assessment platforms
  • 2026-05-02: Created structured startup idea pages

Key Insights​

What makes a good solo founder software startup:

  1. Pure software (minimal human ops)
  2. AI amplification potential (LLMs reduce team needs)
  3. Clear willingness to pay (validated by competitors)
  4. Viral distribution channel (open-source, free tier)
  5. Fast iteration cycle (weeks to MVP, not months)
  6. Global market (not geography-constrained)

Anti-patterns to avoid:

  1. Marketplace (chicken-egg problem)
  2. Heavy sales cycle (enterprise sales)
  3. Physical fulfillment
  4. Regulatory heavy (fintech, healthcare)
  5. Hardware dependency
  6. Human operations required
