When you’re growing fast, you don’t always have months of engineering time to build the perfect system. ResortPass wanted to deliver location-relevant offers to every user—without waiting for a backend build. Using Iterable’s flexible Catalog feature, they launched a “Preferred Location Engine” in days, not months, enriching user profiles based on real behavior. That early, scrappy version proved its value, shaped the data model, and paved the way for today’s scalable API-driven engine. Join ResortPass and Modular Marketing to see how creative use of Iterable’s tools can accelerate personalization and evolve with your growth.
