In most circumstances, it is best for all the investment management presenters to shake the hands of all the investment board and staff of the prospective client before the finals presentation actually begins.
There are a few exceptions. For example, if the room is long and narrow and the prospective clients are all huddled together at one end and you and the team are at the other end of the table, it could be awkward at best to shake hands with everyone.
Nonetheless, the advantage of making the effort is that you will have eye contact with all the attendees and with a firm handshake, you can put a name with a face.
More importantly, the prospective client will be more likely to remember names, faces and roles at the investment firm. Such recognition could be very important during both the presentation and the post-presentation discussion among board and staff. If the board and staff can remember the names of the team members and put a face with those names, then the prospective client is more likely to remember something important that the team member said about the firm, the strategy or the process. Such recognition will differentiate the firm from the others.
However, be mindful that you may be the last firm to present, meaning the prospective client's attention might be taxed. This is why common sense and being able to assess quickly the dynamics in the room and the logistics are essential skills for the sales executive. If the room is really impossible to navigate somewhat gracefully, then introduce to the audience each member of your team with name and function within the firm.
Hopefully, your contact at the prospective client with whom you have undoubtedly met many times during the due diligence process will introduce all of the board and staff to your team with names and functions.
Also remember that you have a time limit for your presentation. The time it takes to have everyone shake hands might be eating into the discretionary time you have to make your presentation.
In short, make the effort because shaking hands is part of the basic fabric of social interaction.
