Offer a fixed-price concierge service that compares all-in ticket costs, checks listing and venue restrictions, supervises transfers into each attendee's account, and prepares transaction records for disputes. Begin as a manually delivered service using screen sharing, documented checklists, and marketplace support channels; later productize repeatable verification and transfer steps without attempting to replace the ticket marketplaces.

Mobile-only tickets, marketplace cross-listing, dynamic pricing, and expensive event travel have increased both transaction complexity and the cost of failure. The reviews show similar trust and support failures across multiple marketplaces rather than one isolated product defect.
