Two Sets of Books: Startup Founder Who Pleaded Guilty to Defrauding Investors Now Faces SEC Case

Published Oct. 15, 2026. Case statuses are current as of that date.

Startup pitch decks are built to impress: fast-rising revenue, big-name customers, a growth chart that only goes up. Federal prosecutors say one young founder's deck was impressive because it was false, and that she kept a second, honest set of books out of investors' sight.

Gökçe Güven, 26 at the time of her plea, of New York, New York, and Turkey, the founder and former CEO of New York fintech startup Kalder Inc., pleaded guilty in May 2026 to one count of securities fraud in Manhattan federal court [1]. On Oct. 2, 2026, the Securities and Exchange Commission filed a related civil case against Güven and Kalder [2].

Status note: Güven's guilty plea is confirmed by the U.S. Attorney's Office; she has not yet been sentenced. Kalder Inc. has not been criminally charged in the sources we reviewed, and the SEC's civil allegations against the company are unproven.

How the scheme worked, according to prosecutors

According to the U.S. Attorney's Office for the Southern District of New York [1]:

1. The pitch. Güven promoted Kalder as a "fintech-marketing platform" that brands could use to create and monetize customized reward programs. In April 2024 she began raising a "seed round" from dozens of venture capitalists.
2. Inflated customers. Her pitch deck claimed 26 brands were "using Kalder" and 53 were in "live freemium." Prosecutors say some of those brands had only short, heavily discounted pilot programs, and others had no agreement with Kalder at all.
3. Invented growth. The deck claimed recurring revenue had grown month over month since February 2023 and reached $1.2 million in annual recurring revenue by March 2024.
4. Two sets of books. Güven allegedly kept one accurate set of financials prepared by Kalder's outside accounting firm, and a second, inflated set that went to investors.
5. A forged contract. She also sent prospective investors a forged contract with a purported brand partner.

Prosecutors say she raised about $7 million from more than a dozen investors. U.S. Attorney Jay Clayton said Güven "defrauded more than a dozen venture capital investors through material misrepresentations about Kalder's revenue and brand partners, then lied to obtain an immigration benefit" [1].

The visa. According to prosecutors, after her student visa expired, Güven had Kalder sponsor her for an O-1A visa, which is meant for people with extraordinary ability. The application repeated the same kinds of misrepresentations and included reference letters she had digitally signed herself in executives' names without their knowledge. She received the visa in fall 2025 [1].

The SEC's civil case

The SEC alleges that from about April through at least December 2024, Kalder and Güven raised about $6.7 million through false and misleading statements, overstating revenue and counting free "demo accounts" and short-term discounted pilots as revenue-generating customers [2].

Güven agreed to a two-part (bifurcated) settlement, subject to court approval. Without admitting the allegations, she consented to a judgment that would permanently enjoin her from violating the charged provisions and impose a six-year officer-and-director bar, with disgorgement, interest and civil penalties to be set later by the court [2][3]. The SEC release does not describe any settlement by Kalder Inc.

Why ordinary investors should care

This case involved venture capital firms, but the same tactics show up in pitches to everyday investors through crowdfunding portals, private placements and "friends and family" rounds. If professional investors with due-diligence teams can be shown false numbers, so can you.

Red flags in a startup pitch

• Revenue or customer numbers you can't tie to contracts, bank statements or an outside accountant's reports.
• Lists of brand "partners" or logos without signed agreements you can check.
• Pressure to invest quickly before a round "closes."
• Reluctance to let you speak with the company's outside bookkeeper or accountant, or with named customers.

What to do

1. Ask for financials prepared or reviewed by an independent accountant, and compare them with the pitch deck.
2. Contact customers yourself to confirm they actually pay for the product.
3. Check offering filings on the SEC's EDGAR database and look up promoters on Investor.gov.
4. Report suspected securities fraud to the SEC at sec.gov/tcr.
