"[2] 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.

[7] In October 2015, Paribus announced that it had raised $2.1 million in seed funding, following its participation in the Y Combinator summer program and Startup Battlefield at TechCrunch Disrupt NY.

[11] Paribus connected to a user's email account to scan messages for receipts from e-commerce retailers.

[20] At its launch, the service worked with 18 major retailers, including Amazon.com, Best Buy, Walmart, Target, Macy's and Newegg.
