Jay Freeman (also known as "saurik") is an American businessman and software developer. He is known for creating the Cydia application suite.

Freeman studied Computer Science and graduated from the College of Creative Studies, University of California, Santa Barbara, where he then studied for a PhD.[1][unreliable source?] He is a member of the iPhone Dev Team development community (for the iPhone OS).[2][unreliable source?]

He created the Cydia software application for Apple's iOS operating system, which runs on phones jailbroken so that they can run applications developed by third parties.
