In principal, no. You have autonomy over which investors you allow to interact with the startups you’ve scouted. If, for whatever reason, you do not want an investor to interact with a startup you’ve scouted, you’re under no obligation to provide said investor with access.
However, for our Beta, we are limiting this autonomy and have opted to facilitate deck and intros automatically as and when an investors requests so.
Only investors who are following your dealflow or whom you have shared a particular deal with can request deck or intros. And you still have complete control over who can follow your dealflow, and can delete a follower anytime you see fit.
