The company says its decision to go this route was driven by customer activity. Dining is a top spending category among cardholders and the number one request through the Platinum Concierge service - a premium perk that’s like having an assistant work for you to research travel, find gifts or make dinner reservations, for example.

Resy fits in with Amex’s larger goal of providing services to cardholders that can help connect them to unique experiences, as its platform can be used to acquire reservations even at newer, hipper and hard to get into restaurants.
