Build-DNA

Turn who you are → into what to build → into how to sell it.

A Claude skill that generates personalized business ideas and complete go-to-market plans — based on your unique background, skills, resources, and network. Not another SaaS idea generator. A full thinking partner that starts with you and ends with a 72-hour action plan.

Why Build-DNA Exists

Most idea generators give you the same 10 ideas as everyone else.

Build-DNA is different. It starts by learning who you are — your skills, your network, your unfair advantages, where you've lived, what you obsess over, who you know. Then it generates ideas that only you could build. Then it tells you exactly how to sell them.

The result: business ideas matched to your DNA, not a generic market map.

Who It's For

• Vibe coders and builders who want to ship something real, not just practice projects
• Hackathon participants who need a strong concept in 24 hours
• First-time founders who have energy but no clear direction
• Serial entrepreneurs who want to brainstorm new opportunities fast
• Freelancers and consultants who want to productize their skills
• Anyone who's ever said "I want to start something but I don't know what"

What You Get

Build-DNA runs three phases:

Phase 1 — DNA Scan

Adaptive intake: Claude asks you questions about your skills, interests, network, location, resources, and motivations. Depth adapts to your situation — a hackathon builder gets 4 questions, a first-time founder gets a full profile session.

Phase 2 — Idea Generation

5–10 personalized business ideas across every category: software, physical products, e-commerce, content businesses, cross-border arbitrage, hardware+software, services, creator economy, and more. Each idea is tied to your specific unfair advantages.

Phase 3 — Build Brief

For your chosen idea(s), a complete build document:

1. Clarity Statement — what it is, for whom, why it works
2. Opportunity Map — 6-dimension analysis (pain, urgency, WTP, distribution, competition, difficulty)
3. Founder Fit Score — honest assessment of personal fit and risks
4. Business Model Options — 2–3 ways to make money, with pricing logic
5. Marketing & Sales Plan — first 100 customers, channels, positioning, launch sequence
6. Cofounder & Team Profile — what you're missing, who to find, alternatives
7. Founder Skill Development Plan — what to learn, how fast, specific resources
8. Next 72 Hours — 9 concrete actions to take starting now

How to Use

Build-DNA activates automatically when you describe what you're trying to do. Just start talking:

I want to start a business but I don't know what to build.

I'm at a hackathon. I need a solid idea in the next hour.

I've been a nurse for 8 years. I want to build something using what I know.

Help me find an idea I can start this weekend with $500.

I keep seeing this product in Japan that doesn't exist in Europe. How do I build a business around it?

Or trigger directly:

/build-dna I'm a 25-year-old graphic designer with 2k Instagram followers and $2k saved.

Philosophy

• Personal beats generic. Every output should feel like it was written for you, not copy-pasted from a startup blog.
• All business types are valid. A Korean stationery import business is as legitimate as a SaaS. A newsletter is as real as an app.
• Distribution deserves product-level rigor. Where your first 100 customers come from is a product decision, not a marketing afterthought.
• Honest over hype. Real risks, real timelines, real kill criteria. You deserve better than false confidence.
• Action over analysis. Every session ends with something you can do today.
