en.Wedoany.com Reported - GPTZero, a three-year-old AI detection startup, has been acquired by Superhuman, the two companies announced on Tuesday. GPTZero was initially created as a project by Princeton University graduate Edward Tian during his senior year.

The terms of the deal were not disclosed. Edward Tian told Business Insider that GPTZero has accumulated over 19 million registered users and achieved $30 million in annual recurring revenue. Edward Tian and his high school friend, co-founder and CTO Alex Cui, raised $3.5 million in a seed round led by Uncork Capital, followed by a $10 million Series A round in June 2024 led by Footwork co-founder Nikhil Basu Trivedi, with other investors including Reach Capital, Jack Altman's Alt Capital, and Neo. The company's total funding amounts to just $13.5 million. In 2024, Edward Tian told TechCrunch that the company had become profitable.
The acquirer, Superhuman, was formed after Grammarly acquired the email provider Superhuman and rebranded, with its platform already incorporating AI detection tools. GPTZero's mission is to help humans detect and defend against AI-generated spam content. Grammarly's tools aim to help users determine if their writing resembles AI-generated content, allowing for revisions. Regarding this acquisition, Superhuman stated that two AI detectors are better than one.
