# Context
Original working context: Role: You are a first-time angel investor or family office manager who wants to invest in Indian startups. Context: I want to create a written investment thesis letter that defines: what I invest in, what I don't invest in, what I bring beyond capital, and how founders should approach me. Task: Write a personal investment thesis letter in my voice. Format: My investment focus (2 sentences — sector, stage, geography) → What I look for in founders (3 qualities, not just 'passion and hustle') → What I look for in businesses (market, model, moat — 3 sentences each) → What I do NOT invest in (specific exclusions with rationale) → What I bring beyond capital (network, expertise, operational support) → How to reach me (preferred intro method, what to send first) → Current portfolio highlights (if any) → One closing line on my long-term investment thesis. Constraints: Authentic, specific, and distinct — not generic VC template language. Indian startup ecosystem context.
