Groupon (GRPN +2%) is both moving upmarket and challenging OpenTable (OPEN -1.7%) by launching Groupon Reserve, a reservation service for high-end restraurants that promises discounts of up to 40%.10 U.S. markets are initially supported; Groupon plans to add more U.S. cities, and some international ones, by year's end. Reserved relies on a reservation engine obtained via the acquisition of Savored, and (unlike OpenTable) is focused on moving inventory at the last minute or during periods of weak demand. Groupon adds Reserve will eventually feature deals from "top beauty, product, travel and entertainment brands, as well as similar reservations capabilities for spas, salons and hotels."
