Bill Gates' Daughter's Phia Accused of Cookie Stuffing Fraud
Phoebe Gates, daughter of Bill Gates, has been accused of using the e-commerce plugin Phia to inject its own channel codes during user checkouts, allowing it to claim commissions from merchants even when purchases were not made through Phia.
A Bloomberg investigation revealed that the Phia browser extension opens a background tab during the checkout process, overriding other affiliate referral codes.
Independent tests and competitor validations found that this behavior led Phia to claim commissions on sales it did not actually facilitate.
The company responded that this was a coding issue that has been fixed, but subsequent reports indicate that relevant personnel may have been aware of the issue earlier.
Similar cookie stuffing practices have previously been prosecuted as telecom fraud in eBay promotions, with involved parties receiving prison sentences.
In the market, disputes over affiliate attribution are driving merchants and platforms to strengthen scrutiny, benefiting legitimate promoters from reinforced rules, while tools accused of violations face account suspensions and declining revenues.

Phoebe Gates and her partners founded Phia in 2025, raising over $40 million, positioning it as an AI shopping assistant that monetizes through affiliate commissions, but its extension features have been accused of deviating from user-initiated choices.
In terms of capital pathways, the product attracts users with discount discovery but captures commissions for sales not driven through backend attribution, shifting resources from genuine traffic to technical overrides, motivated by rapid revenue scaling.
Similar cases include the class action lawsuit against PayPal's Honey for cookie stuffing and early eBay affiliate fraud cases; Phia is currently in its startup phase facing compliance and reputational challenges.
The structural judgment indicates a transfer of pricing power: affiliate attribution rules are circumvented by technical means, utilizing browser extension permissions to rewrite referral codes, thus redistributing commission flows.
