Phoebe Gates’ Startup Phia Faces Scrutiny Over Alleged Cookie-Stuffing Controversy

Phoebe Gates and Sophia Kianni’s startup Phia is facing scrutiny over alleged cookie-stuffing practices that may have inflated affiliate sales commissions. Here’s what the reports say about the controversy.

Phoebe Gates’ Phia Startup Under Investigation Over Alleged Cookie-Stuffing Claims

Phoebe Gates, the 23-year-old daughter of Microsoft co-founder Bill Gates, is facing renewed scrutiny after reports raised questions about the affiliate-marketing practices used by Phia, the digital shopping startup she co-founded with Sophia Kianni.

The controversy centers on an online marketing technique known as cookie stuffing, in which affiliate-tracking cookies may be placed on a user's browser without the normal action that would establish the affiliate's legitimate role in generating a purchase.

Reports cited internal company communications and people familiar with the matter as alleging that certain Phia features could have caused the company to receive credit for online purchases even when customers had not actively used Phia's promotional tools.

Phia has disputed aspects of the reporting and said it has already removed features responsible for misattributions, reviewed transactions and begun reversing affected commissions.

The controversy has nevertheless placed the young startup under significant attention because Phia had attracted substantial investment and high-profile backers.

What Is Phia?

Phia is a digital shopping assistant designed to help consumers find products, promotions and discount opportunities while shopping online.

The company was founded by Phoebe Gates and Sophia Kianni, who met during their time at Stanford University. Phia operates through technology that can interact with online shopping experiences and help users discover deals.

The startup reportedly raised approximately $30 million in 2025, with investors and prominent figures including Hailey Bieber, Kris Jenner and Spanx founder Sara Blakely among its backers.

The company's business model includes affiliate relationships with retailers. When a customer uses an affiliate's promotional link or coupon and subsequently completes a purchase, the affiliate can potentially receive a commission from the retailer.

That model is common throughout the digital advertising and e-commerce industries.

However, affiliate systems depend heavily on accurate attribution.

That is where the controversy surrounding Phia emerged.

What Is Cookie Stuffing?

Cookie stuffing, sometimes referred to as affiliate cookie stuffing, involves placing tracking cookies on a user's device without a legitimate qualifying interaction.

Affiliate cookies are normally intended to help retailers identify which website, service or marketing partner referred a customer.

For example, if a shopper intentionally clicks a legitimate affiliate link before purchasing a product, the affiliate platform can record that interaction and potentially assign a commission to the referring partner.

Cookie stuffing becomes controversial when a tracking cookie is placed without the customer meaningfully interacting with the affiliate promotion.

In such circumstances, an affiliate could potentially receive credit for a transaction it did not actually generate.

Legal consequences can vary depending on the conduct, evidence and applicable laws. Legal experts cited in reports have warned that deceptive affiliate practices can potentially lead to serious legal exposure, including allegations involving wire fraud.

Importantly, an allegation or report about potentially improper conduct does not by itself establish criminal liability.

Reports Raise Questions About Phia's Tracking Features

According to reports, concerns surrounding Phia's affiliate-tracking practices extended back several months before the company publicly described the issue as a software problem.

Bloomberg reportedly reviewed internal Slack messages and company information that raised questions about how certain Phia features operated.

One feature reportedly involved automatically dropping an affiliate cookie when Phia's browser extension appeared on a website where coupons were available.

That could potentially mean a customer did not need to actively select or use a coupon before Phia received attribution for a transaction.

The distinction is important because affiliate commissions are generally designed to reward marketing activity that actually contributes to a sale.

Phia has said that features causing misattributions were removed and that it is reviewing transactions to identify affected brand partners.

Phoebe Gates' Reported Internal Messages

One of the most closely examined elements of the controversy involves messages reportedly attributed to Phoebe Gates.

According to the reports, Gates expressed concerns that Phia was not generating as much commission from Etsy as she expected.

She allegedly asked developers about ensuring that the company's tracking technology was active across websites where Phia had coupon opportunities.

The messages have drawn attention because they appear to raise questions about whether company leadership understood how the tracking features were functioning.

However, the meaning and context of internal communications can be complicated, and the reports do not by themselves establish that Gates personally committed a crime.

The distinction between being aware of a technical feature, approving a business strategy and intentionally participating in unlawful conduct is legally significant.

Sophia Kianni Also Mentioned in Reports

Phia co-founder Sophia Kianni has also been mentioned in reporting about the controversy.

According to the reports, Kianni discussed a proposed feature that could potentially place an affiliate cookie when a user attempted to close a Phia pop-up.

The idea reportedly encountered restrictions involving Google's Chrome browser and affiliate-cookie practices.

A Phia spokesperson subsequently said that the feature was never implemented.

This is another important distinction: a proposed or discussed feature is not necessarily the same thing as a feature that was actually deployed to customers.

Phia Says It Has Taken Corrective Action

Phia has maintained that it responded to the issue and removed features responsible for misattribution.

The company said it began reviewing transactions and issuing reversals to brand partners where inappropriate attribution occurred.

Phia also said it planned to hire a head of compliance.

That move could become important as the company attempts to strengthen oversight of its affiliate relationships and reassure retail partners.

The startup has also argued that reports about the size of its revenue decline overstated the role played by cookie-related features.

According to Phia, it disabled multiple monetization features during the same period, meaning that a drop in revenue cannot necessarily be attributed entirely to the tracking controversy.

Why the Revenue Figures Matter

One of the most striking elements of the controversy is the reported change in Phia's daily revenue after certain features were disabled.

Reports indicated that average daily revenue dropped substantially after the company switched off the features in July.

Bloomberg reportedly cited internal data showing daily revenue falling from roughly $80,000 to between $10,000 and $28,000.

The report also claimed that cookie-related activity accounted for a significant portion of the merchandise value Phia claimed credit for in June.

Phia disputed the interpretation, saying the company had simultaneously disabled much of its monetization infrastructure.

If the reported figures are accurate, the situation could raise broader questions about the sustainability of Phia's revenue model.

Retailers Could Be Affected

The controversy does not only concern Phia.

Affiliate marketing involves relationships among technology companies, affiliate networks, retailers and consumers.

Major retailers reportedly connected to the disputed attribution activity included companies such as Nike, Gap and Nordstrom.

If a retailer pays a commission to an affiliate that did not legitimately generate a sale, the retailer may effectively be paying for attribution it did not receive value from.

That is why affiliate networks typically have rules governing how tracking cookies and promotional links can be used.

Reports indicated that Impact.com, one of Phia's affiliate partners, suspended the network and reallocated commissions associated with the company.

Could Phoebe Gates Face Criminal Charges?

The reports have prompted discussion about possible legal consequences, but it is important not to confuse potential legal exposure with an actual criminal case.

Legal experts quoted in media reports have said that deceptive digital practices can, under certain circumstances, potentially fall within federal fraud laws.

However, whether conduct constitutes a crime depends on numerous factors, including intent, knowledge, the specific technology involved, financial losses and evidence available to investigators.

There is no basis simply from the reported allegations to conclude that Phoebe Gates will be prosecuted or imprisoned.

Any criminal liability would require appropriate investigation and legal proceedings.

A Major Test for Phia

The controversy represents a significant challenge for a young company that had quickly attracted attention from investors and celebrities.

Phia's brand is built around helping consumers shop more intelligently and efficiently.

Trust is therefore particularly important.

Retail partners need confidence that sales attributed to Phia are legitimate, while consumers need confidence that the technology is behaving as advertised.

The company's decision to review transactions, reverse inappropriate commissions and strengthen compliance could help rebuild that trust.

At the same time, investors and business partners may closely examine the company's internal controls and affiliate-marketing policies.

Phoebe Gates' Growing Public Profile

The controversy also places greater attention on Phoebe Gates herself.

As the daughter of Bill Gates, she has faced intense public interest since entering the business and technology world.

Gates has previously spoken about wanting to establish her own identity and prove herself independently of her family's enormous wealth and influence.

Her involvement with Phia has consequently attracted attention beyond the startup's technology.

For Gates, the current controversy may become an important test of how she and her company respond when confronted with questions about business practices and internal controls.

What Happens Next?

The immediate priority for Phia is likely to be determining exactly which transactions were affected and ensuring that retailers receive appropriate corrections.

The company will also need to demonstrate that its tracking technology complies with affiliate-network rules and relevant regulations.

A stronger compliance structure could help prevent similar issues in the future.

For investors, the bigger question may be whether Phia can maintain a viable business model after removing the disputed tracking features.

For consumers, the controversy highlights the importance of understanding how browser extensions and affiliate-shopping tools operate behind the scenes.

Takeaway

The allegations surrounding Phoebe Gates and Phia have sparked an important debate about transparency, affiliate marketing and the responsibilities of rapidly growing technology startups.

Reports allege that certain Phia features resulted in affiliate cookies being placed in circumstances that may have allowed the company to receive credit for sales without the expected customer interaction.

Phia has acknowledged misattributions, said the relevant features were removed and stated that it is reviewing transactions and reversing affected commissions.

The company has also disputed parts of the reporting, particularly interpretations surrounding the scale of the revenue impact.

At this stage, the controversy should be understood as a reported dispute involving alleged affiliate-tracking misconduct, rather than proof that Phoebe Gates has committed a criminal offense.

The coming months could reveal whether Phia successfully resolves concerns with retailers, affiliate networks, investors and customers—and whether the startup can continue growing while maintaining stronger compliance standards.
