What Platform does Epicor host their Virtual Summit On

Does anyone know what meeting software Epicor is using to host their Virtual Summit each year? I like how there is a “Lobby” and various “Rooms” where you can choose to attend sessions and even a “Virtual Trade Show” to visit certain vendor booths.

Seems like a lot for them to code for themselves. Does anyone know if they are using a particular software that is out there?
