There are several grievances early-stage founders have against startup investors, especially related to approachability & communication. Some of them are — investors never respond to emails, they can at least acknowledge founder emails, they vanish after first call or meeting, and worse, they are snobs. Of course there are other criticisms, like investors don’t know what they’re doing, they fund bad startups, they don’t respect cash or profitability, etc. — but these are topics of another post.
Coming back to the complaints on approachability & communication, the answer is that these are both right and wrong. Some investors are good at this, some are bad.
