The gap between "idea" and "first paying customer" is where most solo founders fail — not from lack of effort but from lack of a structured, day-by-day system. A tool that compresses that gap from months to 14 days with templates already customized to their specific idea removes the activation barrier that kills most ventures before they start. The market evolves faster than any fixed playbook. The prompts and templates that worked in 2024 may not work in 2026.
Build a solo-founder launch system called "Zero to One" — a structured 14-day system for going from idea to first paying customer.
Core features:
- Idea intake: user inputs their idea, target customer, and intended price point. [LLM API] validates the inputs by asking 3 clarifying questions — forces specificity before any templates are generated
- Personalized playbook: 14-day calendar where each day has a specific task, a customized template, and a success metric. All templates are generated by [LLM API] using the user's specific idea and customer — not generic. Day 1: problem validation script. Day 3: landing page copy. Day 5: outreach email. Day 7: customer interview guide. Day 10: sales conversation framework. Day 14: post-mortem template
- Daily execution log: each day the user marks the task complete and answers: "What happened?" and "What's the specific blocker if incomplete?" — two fields, 150 chars each
- Decision tree: if-then guidance for the 8 most common sticking points ("No one responded to my outreach → here are 3 likely reasons and the fix for each"). Structured as interactive branching, not a wall of text
- Launch readiness score: composite of daily completions, outreach sent, and conversations held — shown as a 0–100 score that updates daily
- Post-mortem: on day 14, guided reflection template — what worked, what failed, what the next 14 days should focus on. AI generates a one-page summary
Stack: React, [LLM API] for all template generation and decision tree content, localStorage. High-energy design — daily progress always front and center.
