Improve your Virtual Event with Chat Messaging

Connect your attendees, hosts during virtual events as they unfold in real-time. Build real-time networking between attendees, with dedicated chat groups and more.

Chat for Online Events Platforms

Two of the biggest challenges for attendees is engagement and interaction. Since most virtual event attendees join to learn something new, they expect the platform to have reliable tools to interact with the host and other attendees. And without chat, they will drop off quickly. Real-time chat messaging is considered a necessary feature for online events to be successful.
