If you need some level of human interaction in order for your event to be successful, but know that many of your attendees will be unable to attend in person, a hybrid event is an extremely useful solution. If you’re unsure, a pre-event survey can be helpful.
Obviously, if more than 90% of your audience sways one way or the other, there’s no need for a hybrid model. However, if the time and cost of travel is a deterrent for a percentage of your audience, or some attendees have health and safety concerns, or the venue has capacity limitations, a hybrid event is an extremely useful solution.
