Nice insight. Reminds me of another problem: targeting.

If the target customers have already found each other, it's an easier sell. If they haven't then you have a "customer diaspora"

For instance, if I have a new game, there's plenty of organizations, institutions, and forums I can introduce my game on.

If instead, I have productivity software that helps disorganized people manage time better, there's no "disorganized users group" or "decluttering news" website to find the people ... it's a slog. Where would those people concentrate? A bar on a weekday night maybe? The most inconvenient parking spaces of an office park? I don't know.

At least to me this is a harder problem
