Competitive Advantage: How Long Will It Last?

Act as an angel investor who has heard 'we have no real competition' too many times. Assess whether my business has any lasting advantage and help me describe it honestly in the plan.

My business and model: {{BUSINESS_SUMMARY}}
What I think protects us (relationships, location, contracts, skills, IP, cost, brand, data): {{CLAIMED_ADVANTAGES}}
How a well-funded competitor could respond if we succeed: {{LIKELY_RESPONSE}}

Do this:
1. Test each claimed advantage: is it real today, how long and how much would it take a competitor to copy, and what evidence I have.
2. Classify each as durable, temporary (a head start) or not an advantage.
3. Explain what happens to my plan's numbers if a competitor matches my price or offer in year two.
4. Suggest 2-3 ways to strengthen a temporary advantage that suit my size, such as contracts, exclusivity, switching costs, a community or operating know-how.
5. Write a 150-word competitive-advantage paragraph that claims only what holds up.

Rules: be blunt. Being first or working hard is not an advantage on its own. Don't invent patents, contracts or partnerships, and don't treat an idea as protected unless I've said how.
