Paribus is an American company and creator of the price tracking app of the same name, which syncs with a users email account to scan for receipts and negotiates with online companies to refund the difference if there is a price drop shortly after a purchase. Paribus was founded in 2014 by Eric Glyman and Karim Atiyeh. The company is based in Brooklyn, New York. The name is derived from the Latin phrase ceteris paribus, meaning "all others things being equal." Glyman built Paribus to simplify the process of receiving a refund following a price drop, which can be complicated to track and often go unclaimed. He and fellow Harvard University alumnus Atiyeh conceived of the idea and started working on the concept in the summer of 2013. After launching in beta in September 2014, the app launched publicly at TechCrunch Disrupt New York on May 5, 2015. Paribus released its iOS app on August 6, 2015, and its Android app on April 28, 2016.
