Empyr powers online-to-offline (O2O) marketing programs for some of the world’s largest websites and apps. The company is redefining O2O performance marketing by combining the power of card-linked technology and customer loyalty in its groundbreaking CPR™ (Cost Per Revenue) platform. Empyr enables brands to advertise offers online such as 10% cash back and pay only for in-store sales. CPR takes the guesswork out of calculating advertising ROI with 100% attribution from an online ad to an in-store sale and incremental lift analysis. Direct integrations with all three leading credit card associations make it possible for online consumers to redeem offers at offline merchants such as restaurants and retail stores, in a frictionless way, simply by paying with a debit or credit card. Empyr’s growing network of partners currently includes Yelp, LivingSocial, Coupons.com, Swagbucks and over 1,500 other websites and apps.
