Will be hard to pre sell tickets on this platform then convert to a venue’s ticket. Most of them have exclusive ticketing deals that won’t allow this or severely limit % that can be sold. That’s why the focus is on “perks”
I think one way to get around this would be to show the venues the money has already been made. This includes the price of tickets. If there are ticketing deals involved, it could be something like a straight cash exchange: We have 100 people who gave money for entry. Here's x amount money for 100 tickets.
Open to any suggestions you might have!
