Why don't you share some basic info about the business, your previous experience etc, instead keeping it a secret and expecting that someone will just contact a brand new account without any info whatsoever?
It might be because:
1) He truly dreams about opening a big business but he has no idea how opening a big business works.
and/or
2) He does not care about the quality of investors since no reasonable person would feel attracted to an OP like that (even in my case, although I don't like to systematically think the worst about strangers, I'm aware that this way of being carries a risk so I always force myself to make informed decisions).
Not like I had much money to invest :-(This kind of posts are very frequent in this subsection, but I'm still not sure what is the main reason to do that in most cases
because as I said, for reasonable people, no information no decision, apart from the decision to opt out.
