Passage is a Detroit-based event ticketing and payments platform for small and mid-sized events and attractions. Its all-in-one 'mobile box office' handles online and at-the-door sales of tickets, merchandise, concessions, and season passes, plus mobile check-in, reserved seating charts, waivers, and virtual queues. The company charges no setup fee, monthly subscription, or long-term contract, earning instead a low per-transaction service fee that organizers can pass on to ticket buyers. Founded in 2014, Passage has sold over 8 million tickets and serves customers in all 50 US states as well as Canada and Australia.
