Currently, the Forbes 30 Under 30 list has become more than a little infamous because of the number of entrants who keep getting accused of cheating. Notable alumni include FTX founder Sam Bankman-FriedFrank CEO Charlie Javice, Joanna Smith-Griffinfounder of AI startup AllHere Education, and “pharma bro” Martin Shkreli, among others. Now, another member of the list has been hit with federal charges.

Gökçe Güven, a 26-year-old Turkish national and the founder and CEO of the fintech startup callIS charged last week with alleged securities fraud, wire fraud, visa fraud, and aggravated identity theft.

The New York-based fintech startup – which uses the “Turn Your Rewards into (a) Revenue Engine” tagline – says it will help companies create and monetize individual rewards programs. The company was founded in 2022, and offers participating companies the opportunity to earn continuous revenue streams through affiliate marketing, Axios previously reported.

Güven was featured in the Forbes 30 Under 30 list last year. The magazine writing notes that Güven’s clients include chocolate major Godiva and the International Air Transport Association, the trade organization that represents most of the world’s airlines. Kalder also admits to enjoying backing the several well-known VC firms.

The US Department of Justice says that, at the time of Kalder round seed in April of 2024, Güven managed to raise $7 million from more than a dozen investors after presenting a pitch deck full of false information.

According to the government, Kalder’s pitch deck claims there are 26 brands “using Kalder” and another 53 brands “live freemium.” However, officials say that, in fact, Kalder, in many cases, only offers heavily discounted pilot programs to most companies. The other brands “have no agreement with Kalder whatsoever—not even for free services,” officials said in a press release announcing the accusation. The pitch deck also “falsely reported that Kalder’s recurring revenue has grown steadily every month since February 2023 and that as of March 2024, Kalder reached $1.2 million in annual recurring revenue.”

The government also accused Güven of keeping two separate sets of financial books. One of the sets included “false and inflated figures,” and was presented to investors or potential investors to hide the “true financial condition of the company,” the government claimed. The DOJ also alleged that Güven used lies about Kalder as well as forged documents to obtain a visa category reserved for individuals with “exceptional abilities,” which would have allowed him to live and work in the United States.

TechCrunch reached Güven through his personal website. The CEO said he would share a statement about the charges on Tuesday.
