Everything starts with a mail. A paragraph, a list, a vague feeling — whatever you have is enough to begin. I read every one personally and within 24h on weekdays I reply: yes I want to dig in, no this isn't a good fit, or yes but here's a question first.
No form, no funnel. A mail and a reply. The good projects always start with someone saying "I have an idea" in a real sentence — not ticking a budget box.
- A short mail with your idea
- Links / refs (optional)
- Rough timing if you have it
