Wassuh Ulsan
Trip Builder's first B2G case — kicked off in 2022 as part of the Ulsan Metropolitan City Smart Tourism City initiative. A city-scale tourism platform combining the Smart Travel Type Inventory (STTI) with AI-powered recommendations.
Tourism information was scattered across the city
Ulsan's industrial-city image kept barriers high for out-of-town and international visitors. City sites, tourism-board apps, social handles, and blogs were fragmented — a single visitor had to hop across many channels just to plan a trip.
As part of KTO's Smart Tourism City program, the City of Ulsan needed an integrated city-scale concierge. Trip Builder joined the consortium and proposed a solution combining travel-personality analysis with AI-powered recommendations.
