GPTZero's founders, Edward Tian and Alex Cui, initially met and decided to collaborate on the project as they have been friends since high school. When Tian launched an initial version of GPTZero as a web app in December 2022 and received a massive response, he reached out to Cui for help. Cui has a master's in machine learning from the University of Toronto and dropped out of his doctorate program to become a co-founder of GPTZero. Together, they rewrote the app into its current stand-alone platform and raised $3.5 million in seed funding.
GPTZero offers a detection tool that helps identify whether a piece of content was AI generated. Its primary function is to distinguish between human-written text and AI-generated text, using perplexity and burstiness analysis5.
The term "preemptive" in the context of the $10 million Series A funding round for GPTZero signifies that the investment was initiated by the investor, Nikhil Basu Trivedi, before the company founders were actively seeking to raise capital. This type of funding round is advantageous for investors as it allows them to secure a deal before other potential investors become aware of the opportunity, and it indicates strong confidence in the startup's potential for success. In this case, Basu Trivedi played the long game, having met the company's co-founder Edward Tian in 2022, before GPTZero's rapid growth, and maintained contact with him. As a result of this proactive approach, Basu Trivedi was able to lead the Series A round for GPTZero, which had been attracting attention from top VC firms since its launch.
