It’s a tale of the rise and fall of a Forbes 30 Under 30 honoree.
Federal prosecutors have charged Gökçe Güven, the founder and CEO of New York–based fintech startup Kalder, with multiple counts of fraud in connection with a $7 million fundraising round. The case adds to a growing list of high-profile startup founders accused of misleading investors and highlights increasing scrutiny of early-stage fundraising practices in the venture capital ecosystem.
The charges, announced by the U.S. Department of Justice, include alleged securities fraud, wire fraud, visa fraud, and aggravated identity theft. Güven, a 26-year-old Turkish national, was indicted and has not yet entered a public plea.
A growing pattern
The Forbes 30 Under 30 list, once widely viewed as a signal of entrepreneurial promise, has in recent years become associated with a number of fraud cases involving former honorees. Past alumni charged or convicted of financial crimes include former FTX CEO Sam Bankman-Fried, Frank founder Charlie Javice, AllHere Education founder Joanna Smith-Griffin, and Martin Shkreli.
Güven now joins that group, raising renewed questions about the signals investors rely on when backing young founders and the extent to which media recognition may influence fundraising outcomes.
Kalder, which was founded in 2022, markets itself as a platform that helps companies build and monetize customer rewards programs. The startup uses the tagline “Turn Your Rewards into [a] Revenue Engine” and claims to enable businesses to generate recurring income through partner affiliate sales.
High-profile clients
According to Kalder’s public-facing materials and prior media coverage, the company reported relationships with major organizations. Forbes’ profile of Güven stated that Kalder’s clients included luxury chocolatier Godiva and the International Air Transport Association, the global trade group representing most of the world’s airlines. Kalder also claimed backing from several prominent venture capital firms.
Those representations played a central role in the government’s allegations. Prosecutors say Güven relied on exaggerated or false claims about Kalder’s customer base and revenue performance to secure funding during the company’s seed round in April 2024.
Allegations of false metrics
The Justice Department alleges that Güven raised approximately $7 million from more than a dozen investors after presenting a pitch deck that contained materially false information.
According to prosecutors, the deck claimed that 26 brands were “using Kalder” and that an additional 53 brands were in “live freemium.” In reality, officials say many of those companies were only participating in heavily discounted pilot programs, while other brands “had no agreement with Kalder whatsoever—not even for free services.”
The government also alleges that Kalder’s pitch materials misrepresented the company’s financial performance. The pitch deck “falsely reported that Kalder’s recurring revenue had steadily grown month over month since February 2023 and that by March 2024, Kalder had reached $1.2 million in annual recurring revenue,” according to the DOJ.
Prosecutors further claim that Güven maintained two sets of financial records. One set allegedly contained “false and inflated numbers” and was shown to current or prospective investors, while another reflected what the government describes as the company’s true financial condition.
Visa fraud and identity theft charges
Beyond the fundraising allegations, the indictment includes charges related to Güven’s immigration status. Prosecutors allege that Güven used false statements about Kalder’s success, along with forged documents, to obtain a U.S. visa reserved for individuals of “extraordinary ability.” That visa category allows recipients to live and work in the U.S. based on exceptional professional achievements.
The inclusion of visa fraud and aggravated identity theft charges significantly raises the potential legal consequences Güven faces if convicted, as those offenses can carry mandatory sentencing enhancements under federal law.
The startup ecosystem
The case underscores the risks inherent in early-stage investing, particularly when companies are pre-revenue or operating with limited customer traction. It also reflects a broader enforcement trend in which regulators are increasingly willing to scrutinize pitch decks, internal metrics, and immigration filings tied to startup fundraising.
Legal experts have noted that maintaining multiple sets of books or overstating revenue figures can expose founders to severe criminal liability, even when such practices are rationalized internally as optimistic projections or “growth storytelling.”
The charges may also prompt venture firms to reexamine diligence practices, especially in competitive funding rounds where speed often takes precedence over verification.
If convicted on all counts, Güven could face significant prison time, financial penalties, and permanent restrictions on her ability to operate businesses in the U.S. The case is expected to proceed in federal court later this year.
