The Forbes 30 Under 30 list is supposed to identify up-and-comers, but for a notable few fintech honorees, it has identified something else entirely: future federal inmates.
The charges against these former honorees (Forbes has retracted honors in multiple cases due to criminal allegations) range from fabricated revenue figures to forged bank documents, synthetic customer data and misappropriated deposits.
The lesson in these cases is not that fintech is fraud but that hypergrowth narratives and prestigious endorsements are not substitutes for due diligence and risk frameworks.
Forbes acknowledged in 2023 that a small fraction of its more than 10,000 honorees had "turned out to be duds, or far worse," and conceded that while some bad actors were screened out, "others slipped through."
The publication defended its selection process by noting the list is inherently "future-facing," adding that "not even Warren Buffett can predict with 100 percent accuracy."
Here are the seven fintech founders who went from Forbes 30 Under 30 to federal court:
Gökçe Güven — 2025
Most recently, federal prosecutors charged Gökçe Güven, the founder and CEO of rewards fintech Kalder, with securities fraud, wire fraud, visa fraud and aggravated identity theft.
Güven had recently earned a spot on the 2025 Forbes "30 Under 30" list for marketing and advertising.
Last week, federal prosecutors filed an additional aggravated identity theft charge against Güven for allegedly forging a corporate partnership contract to deceive seed-stage investors.
The founder "added the name and falsified the signature" of an executive from a global technology corporation on a fake contract that claimed the brand would pay Kalder $2,500 a month, according to a March 10 superseding indictment from the U.S. District Court for the Southern District of New York.
This latest charge comes on top of previous allegations made by prosecutors in January that Güven scammed seed-round investors out of $7 million by maintaining two sets of books and misrepresenting her company's revenue and client base.
She falsely claimed Kalder generated $1.2 million in annual recurring revenue when it actually brought in only $60,000, according to a January press release from the Department of Justice.
"Güven built her seed round on fake revenue, inflated brand partnerships, and fabricated documents," according to U.S. Attorney Jay Clayton.
Furthermore, authorities allege Güven forged letters of support from business executives to fraudulently obtain an O-1A visa, an immigration status reserved for individuals demonstrating extraordinary abilities.
Nader Al-Naji — 2019
In July 2024, the Securities and Exchange Commission and federal prosecutors charged Al-Naji, a member of the 2019 Forbes 30 Under 30 class, with orchestrating a fraudulent crypto asset scheme.
Al-Naji raised more than $257 million through the unregistered offering of BTCLT, the native token for his social media platform, BitClout. He then falsely assured investors that the proceeds would not be used to compensate himself or other employees.
Instead, Al-Naji diverted over $7 million of those investor funds to pay for personal expenditures, including a Beverly Hills mansion rental and extravagant cash gifts to his wife and mother.
Furthermore, Al-Naji attempted to evade regulatory scrutiny by operating under the pseudonym "Diamondhands" to create the false illusion that the project was decentralized and had no identifiable issuer.
Nate Paul — 2016
In June 2023, federal prosecutors indicted commercial real estate investor Nate Paul, a member of the 2016 Forbes 30 Under 30 list, on eight counts of making false statements to financial institutions.
Paul pleaded guilty to one count of making a false statement to a financial institution in January 2025.
Paul engaged in a scheme to secure approximately $172 million in loans by submitting fake financial records to lenders in Texas, New York, Connecticut and Ireland.
In several instances, Paul provided a counterfeit document that falsely showed he had millions of dollars in a bank account that actually contained less than $13,000, according to a June 2023 indictment.
He also drastically underreported his liabilities and overreported his available cash to influence the lenders' actions, according to the indictment.
Charlie Javice — 2019
In April 2023, authorities arrested Charlie Javice, a member of the 2019 Forbes 30 Under 30 Finance class, for orchestrating a scheme to fraudulently induce JPMorganChase into acquiring her student loan assistance startup, Frank, for $175 million.
A federal judge sentenced Javice to 85 months in prison in September 2025 following a jury trial conviction for conspiracy, wire fraud, bank fraud and securities fraud.
Javice falsely claimed to the bank that Frank had 4.25 million users when it actually had fewer than 300,000. When JPMorganChase asked to verify the user base, Javice hired an outside data scientist to manufacture a synthetic dataset of fake users, according to an April 2023 complaint.
After the acquisition closed, Javice and a co-conspirator purchased data for millions of college students on the open market for $105,000 to cover up the deception, according to a September 2025 press release from the Department of Justice.
Jamie Dimon, JPMorganChase's CEO, last year referred to the bank's 2021 acquisition of Frank as a "
Do Kwon — 2019
In December 2025, a federal judge sentenced Do Kwon, a member of the 2019 Forbes 30 Under 30 Finance and Venture Capital list in Asia, to 15 years in prison for his role in a massive fraud scheme involving his cryptocurrency company, Terraform Labs.
Kwon, whom prosecutors charged with wire fraud and conspiracy to commit securities and commodities fraud, lied to investors about the stability of his company's digital currency, TerraUSD.
He claimed a computer algorithm automatically maintained the coin's one-to-one value with the U.S. dollar. In reality, Kwon secretly used a high-frequency trading firm to artificially prop up the asset's value during a market downturn in May 2021, according to a 2023 superseding indictment.
The scheme ultimately collapsed in May 2022, resulting in "over $40 billion in investor losses," according to the indictment. In addition to the prison term, the judge ordered Kwon to forfeit over $19 million in illegal proceeds.
Caroline Ellison — 2022
In December 2022, Caroline Ellison — a member of the 2022 Forbes 30 Under 30 Finance class and the former co-CEO of Alameda Research — pleaded guilty to seven charges, including wire fraud, securities fraud and commodities fraud.
Ellison, acting at the direction of FTX founder Sam Bankman-Fried, misappropriated billions of dollars in FTX customer deposits to cover massive losses and fund high-risk investments at Alameda.
She also manipulated the price of FTT, an FTX-issued token, to artificially inflate the value of Alameda's collateral, according to a December 2022 press release from the Securities and Exchange Commission.
Furthermore, Ellison knowingly submitted misleading balance sheets to lenders to conceal the firm's extreme risk, according to her September 2024 sentencing memorandum.
Following the collapse of FTX, Ellison cooperated with the government and became a star witness at Bankman-Fried's criminal trial, providing "damning testimony" against him, according to Forbes's 2023 article on bad 30 Under 30 picks.
Sam Bankman-Fried — 2021
Last, but certainly not least: In December 2022, federal prosecutors indicted FTX founder Sam Bankman-Fried — a member of the 2021 Forbes 30 Under 30 Finance class — for his role in a massive financial scheme.
A jury later convicted the former executive of seven counts of fraud and conspiracy, stemming from charges that included wire fraud, commodities fraud, securities fraud, money laundering and campaign finance violations.
Bankman-Fried systematically stole billions of dollars in customer deposits from his cryptocurrency exchange, transferring the assets to his privately controlled trading firm, Alameda Research.
He used the misappropriated funds to cover trading losses, make illiquid venture investments, purchase luxury real estate and enrich himself.
To further his business interests, Bankman-Fried also engaged in corrupt practices, including directing a $40 million cryptocurrency bribe to Chinese government officials to unfreeze over $1 billion in trading assets.
Additionally, the founder orchestrated an illegal campaign finance scheme, funneling tens of millions of dollars to both Democrats and Republicans in an effort to influence cryptocurrency regulation in Washington, D.C.
