Millions of train, bus, flight, and concert tickets go unused every year. Tresta is a trust-based marketplace that connects people who have unused tickets with those who need them. No payments on platform. No markup. Just free matchmaking. Post a ticket, post a wanted request, connect, and arrange the exchange directly. Launched for Sweden (SJ, Västtrafik) and India (IRCTC, RedBus) — expanding worldwide. Ticket swapping done right.
