I don't know how VC or private entities make deals with start-ups, but as far as I know, most of these deals are only about getting tokens very early in a large amount so they can dump on retail investors later down the line. At the very least, they don't openly admit that their decision-making in key areas such as token unlock, exchange listing, change in protocol, etc need permission from their early investors. That being said, you should assume the worst-case scenario and stay away from projects like that for the long term.
