Phoebe Gates, the 23-year-old daughter of Bill Gates and Melinda French Gates, has found her shopping startup, Phia, at the center of a major controversy involving alleged commission fraud. Co-founded by Gates and Sophia Kianni, Phia operates as an application and browser extension that compares prices, identifies discounts, second-hand items, and applies coupons on retail products. The platform has attracted prominent celebrity backers—including Hailey Bieber, Kris Jenner, and others—and raised millions in funding, recently valued at approximately 185 million dollars according to a report by Bloomberg.
Phoebe Gates Startup Phia Faces Scrutiny Over Alleged Cookie Stuffing
The enterprise, which Gates previously described as an effort to build an independent career and establish success detached from her family’s name and privilege, is now facing intense public and legal scrutiny. According to investigative reports, Phia allegedly engaged in a digital marketing practice known as cookie stuffing to falsely claim commissions on online retail sales it did not actually generate.
Understanding the Allegations of Cookie Stuffing and Internal Slack Messages
In digital retail, affiliate marketing systems use tracking cookies to recognize which intermediary link, app, or platform successfully directed a consumer to a purchase, allowing the retailer to pay a legitimate commission. Cookie stuffing involves secretly placing or substituting these tracking tags into a user’s browser without a valid user interaction, referral click, or promotion use. This causes the system to take credit and collect a payout for a transaction it never helped secure.
Internal Slack messages surfaced in reports indicating that leadership was aware of the practice. According to El Periodico, internal communications showed Phoebe Gates inquiring in December 2025 whether automated cookie placement was active across coupon sites to maximize monetization. Co-founder Sophia Kianni also reportedly expressed support for maintaining automated cookie drops, even when users attempted to close pop-up windows. Investigations alleged that this mechanism accounted for approximately 51 percent of the value of sales attributed to Phia during June.
Company Response, Financial Impact, and Operational Changes
Following the public exposure of the practice, Phia took immediate corrective actions. The company deactivated the questioned functions on July 7, initiated a thorough review of registered transactions, promised to reverse payments and return commissions to affected brands, and announced the hiring of a compliance officer to ensure such issues do not recur. Additionally, affiliate network Impact.com temporarily suspended Phia.

The operational adjustments and the suspension of monetization pathways led to a sharp drop in financial metrics. Daily revenues for the startup plummeted from approximately 80,000 dollars down to a range between 10,000 and 28,000 dollars.
Legal Context and Potential Penalties Under Federal Law
Legal specialists examining the case have noted that cookie stuffing operations can potentially be prosecuted as federal wire fraud under United States law, which carries maximum statutory penalties of up to 20 years in prison, alongside potential fines and financial restitution. Legal experts emphasized that prosecutors would bear the burden of proving intent to defraud and the use of electronic communications to execute the scheme.

As of late August 2026, no formal public criminal charges or indictments had been filed against Phoebe Gates, Sophia Kianni, or the company itself. Observers note that while potential exposure includes serious criminal liability, matters can also involve civil claims and financial settlements.
