Amongst all of the younger AI startups being ruthlessly pursued by VCs today, GPTZero has already grown into profitability in its first yr and a half of life, producing tens of millions in income. Based by 24-year-old Edward Tian and 26-year-old Alex Cui, who’ve been mates since highschool, GPTZero presents a detection software that helps establish whether or not a bit of content material was AI generated.
The founders have chosen to take a $10 million “preemptive” Sequence A led by Footwork co-founder Nikhil Basu Trivedi, the workforce has completely instructed gajed. (“Preemptive” is VC-speak for when an investor nabs a deal earlier than the founders had been making an attempt to boost.)
That is fairly the coup for Basu Trivedi. GPTZero has been watched by prime VC corporations virtually since Tian launched an preliminary model as an internet app in December 2022, and 30,000 folks immediately swarmed it, crashing its Streamlit-hosted web site. (Adrien Treuille, Streamlit’s co-founder, who offered to Snowflake for $800 million, later grew to become an angel investor, Tian says.) The corporate formally launched in January 2023.
All through 2024 to this point, as its buyer base has grown, the younger founders had been fielding 4 to 5 calls from VCs per week, they stated.
GPTZero grew 500% in ARR within the final six months, the founders instructed gajed, including that its consumer base has grown from 1 million to 4 million within the final 12 months. This makes it one of many fast-growing client apps of the yr, by some measures.
The corporate has been worthwhile for the final a number of months, they stated, including that they’ve more cash within the financial institution than the overall raised within the lifetime of the corporate. To place a quantity to that: greater than $13 million between its $3.5 million seed and the brand new $10 million.
And the expansion continues. Customers and income have “greater than doubled, possibly even tripled, since January,” Basu Trivedi stated. Whereas they didn’t touch upon valuation, primarily based on a typical 20% Sequence A spherical, the deal has valued the corporate someplace across the $50 million mark pre-money. Different buyers within the spherical embrace education-focused (and women-led) Attain Capital; Jack Altman’s Alt Capital; Uncork Capital (Jeff Clavier’s fund); and Neo (Ali Partovi’s fund).
How the VC received the deal
Basu Trivedi, a Princeton alumni, received the lead on this deal by enjoying the lengthy recreation. He met Tian in 2022, earlier than GPTZero craziness, throughout an annual occasion the place a small group of Princeton college students go to Silicon Valley firms. Basu Trivedi all the time takes the group on a hike of the Stanford Dish.
Tian developed GPTZero whereas he was finding out pc science, pure language processing and journalism on the Ivy League college. Throughout internships for the BBC, and later at The New York Occasions, he wrote code that helped journalists establish AI-generated content material.
After the wild response his preliminary internet app acquired, Tian reached out to his buddy, Cui, for assist. Cui has a grasp’s in machine studying from the College of Toronto and dropped out of his doctorate program to grow to be a co-founder.
The 2 rewrote the app into its present stand-alone platform and raised the $3.5 million in seed after reaching about 1.5 million customers in its first 5 months. This got here principally from angel buyers like Tom Glocer, former CEO of Reuters; Russ Salakhutdinov, Carnegie Mellon College professor and ex-director of AI analysis at Apple (after he offered his startup, Perceptual Machines, to Apple in 2016); and Mark Thompson, CNN’s CEO and former New York Occasions CEO.
Basu Trivedi noticed how GPTZero was gaining press and spectacular angels — and heard the rumblings about it among the many VC scuttlebutt. As a seed investor who backed firms like Canva, ClassDojo and Body.io, he knew a sizzling firm when he noticed one.
He texted Tian in January 2023 to verify in. He wooed the founders together with his community and product know-how from his fast-growth firms like Canva, and with the background of his fund’s co-founder, Mike Smith, former COO of Sew Repair and Walmart.
Traders with each product and operations expertise had been what the 2 20-something founders had been “craving, particularly as Alex and I are studying tips on how to construct a giant firm,” Tian stated.
To show the purpose, shortly after they closed the spherical, Footwork organized a networking occasion with AI leaders, together with Jack Altman (brother to OpenAI’s Sam Altman, who joined the Seed A spherical), who was additionally a school classmate of Basu Trivedi, and Nvidia founder CEO Jensen Huang.
“A giant information benefit“
GPTZero is way from the one firm working to establish AI-generated content material. Others embrace AI Writing Test, Copyleaks, GPT Radar, CatchGPT and Originality.ai.
However many within the AI-detection {industry} have abysmal accuracy, researchers discover. A lot in order that OpenAI, which was pressured by AI-industry paranoia into launching its personal AI detector initially of 2023, shut the software down about seven months later in July, after it was extensively criticized for a way poorly it labored.
Apparently, when gajed’s Kyle Wiggers did his personal experiment with these instruments, all of them flunked besides GPTZero.
Naturally, GPTZero has its personal benchmarks, significantly by way of a partnership with Penn State researchers, that assist it make its case that its tech works effectively, regardless of the {industry}’s basic repute.
Cui says GPTZero is extra correct as a result of it has entry to extra information and has constructed its personal LLM fashions utilizing essentially the most superior open supply instruments, which it received’t disclose.
“Now we have a giant information benefit. Now we have tens of millions of examples of textual content that’s human versus AI,” Cui stated. “We’ve additionally mixed this with among the best-in-class fashions and deep studying. We’re really utilizing language fashions to detect language fashions.”
Whereas the startup could also be finest recognized for serving to academics detect AI-generated pupil work (in October, GPTZero landed an settlement with the American Federation of Lecturers), its buyer base has expanded. It now contains authorities procurement companies, grant-writing organizations, hiring managers, and — particularly attention-grabbing — AI coaching information labelers.
It seems, utilizing AI-generated information for AI coaching “causes mannequin collapse,” Tian says, as a result of educating a mannequin utilizing fabricated examples isn’t one of the simplest ways to get it to perform in the true world.
Naturally, the younger founders have a extra grandiose long-term imaginative and prescient. They need to create a brand new, impartial layer of the web that performs accountability, making certain that human and AI content material is correctly attributed.
To that finish, the workforce is at present engaged on AI hallucination detection. Hallucinations, the place the AI presents AI-generated fiction as if it had been reality, are the bane of the GenAI {industry}. The corporate’s first step towards addressing it is a newly out there free AI textual content copyright verify for LLM coaching datasets. It will assist them generate the coaching information for broader hallucination detection.
“We’re simply making an attempt to keep away from a world the place your entire web is AI-generated content material,” Tian stated. “An web the place all people makes use of AI doesn’t protect the chance for folks to proceed contributing inventive and authentic content material.”
