Turnitin, LLC
The Oakland company that turned a Berkeley graduate student's peer-review tool into the dominant plagiarism checker for schools, universities and publishers worldwide. Successive private-equity owners (Warburg Pincus, then Insight Venture Partners and GTCR) built it into an assessment platform, and Advance Publications bought it in 2019 for ~$1.75bn. Its 2023 AI-writing detector made it the most visible, and most contested, referee of generative AI in student writing.
