One simple and intuitive tool for starting a conversation between participants and exhibitors/sponsors could be a chat or messaging feature within the event platform. This feature could be easily accessible from the sponsor or exhibitor page, as well as from the matchmaking engine.
With this chat feature, participants could send a message directly to the exhibitor or sponsor they are interested in. The exhibitor/sponsor could then respond in real-time, allowing for a quick and easy exchange of information and communication.
Additionally, if the event organizer allows it, exhibitors/sponsors could also request meetings with participants. The participant would then have the option to accept or decline the meeting request, making it easy for both parties to schedule a time to connect.
Overall, a chat or messaging feature within the event platform can be a powerful tool for facilitating communication and connection between participants and exhibitors/sponsors.
