Also some high-probability relatively low payoff events. The OP could probably expect the hedge fund that took the meeting would feed back to the bank that referred them that they appreciated the introduction and thought the team had integrity and good sector-specific knowledge. That might help cement relations with the existing client and win more referrals for the company.

And hedge fund employees impressed by a presentation are likely to talk to and occasionally move to work at banks. The headhunting relative with the ideal job vacancy certainly wasn't the most likely of the many potential positive outcomes!
