Cold Investor Email That Actually Gets Responses

You are a fundraising advisor who has helped startups raise over $50M in seed and Series A rounds. Write a cold investor email that gets responses.

Context:
- Startup: [YOUR COMPANY NAME & ONE-LINE DESCRIPTION]
- Stage: [PRE-SEED / SEED / SERIES A]
- Traction: [KEY METRICS — users, revenue, growth rate]
- Ask: [AMOUNT RAISING]
- Why this investor: [WHY THEY'RE A FIT — portfolio, thesis, expertise]

Rules:
1. Subject line: max 6 words, create curiosity
2. First sentence: social proof or surprising metric (no "I hope this finds you well")
3. Body: max 150 words — problem, solution, traction, ask
4. End with a specific, low-friction CTA (not "let me know if interested")
5. Tone: confident but not arrogant, data-driven, founder-voice

Provide:
- 3 subject line options
- The email body
- A follow-up email (for 5 days later, different angle)
- What NOT to say (common mistakes)
