Act as a challenger-brand strategist. Help {{my_company}} position against {{larger_competitor}} in the market for {{product_category}}. Our advantages, as we see them: {{our_advantages}}. Stress-test those advantages: which ones customers actually care about, which the competitor could copy quickly, and which we can prove. Look for segments or use cases the leader underserves because of its size, pricing, or focus. Keep every comparison factual and verifiable, with no disparagement and nothing that could mislead buyers. Return: 1. The leader's strengths we should not fight head-on 2. Underserved segments and why the leader neglects them 3. Three positioning options, each with a one-line statement, target segment, proof needed, and main risk 4. The recommended option and a homepage headline for it 5. A short answer to the question customers will ask: why not just choose the market leader 6. Evidence to gather next
