About Us

The iParadigms team is a group of dedicated professionals that includes award-winning teachers, graphic designers, computer scientists, and business professionals working together to stop the spread of internet plagiarism and promote new technologies in education. Our offices are located in the San Francisco Bay area.

iParadigms, the company behind Turnitin, got its start in 1996, when a group of researchers at UC Berkeley created a series of computer programs to monitor the recycling of research papers in their large undergraduate classes.

Encouraged by a high level of interest from their peers, the researchers teamed with a group of teachers, mathematicians, and computer scientists to form Plagiarism.org, the world's first internet-based plagiarism detection service.

By late 1998, Plagiarism.org had become the center of international media attention. The small organization was featured in several major media venues, including Good Morning America, World News Tonight, and the New York Times. In the ten years since, Plagiarism.org has continued to grow and evolve, and is now recognized around the world as Turnitin and iThenticate, the internet's most widely used and trusted resources for preventing the spread of internet plagiarism.
