Everything starts with a mail. A paragraph, a list, or just a rough idea. Whatever you've got is enough to start. I read every one myself and reply within 24h on weekdays: yes I'd like to dig in, no it's not the right fit, or yes but I've got a question first.
No forms, no funnel. Just a mail and a reply. The best projects usually start with someone telling me their idea in a normal sentence.
- A short mail with your idea
- Links / refs (optional)
- Rough timing if you have it
