Phia, a Shopping Plugin Co-Founded by Bill Gates’ Daughter, Accused of Faking Affiliate Sales

Phia, a browser extension that uses AI to help users find the best deals on products they want to buy, has been accused of faking affiliate sales by attaching its affiliate code to sales it didn’t actually drive. This tactic, known as cookie stuffing, is a form of affiliate marketing abuse that allows Phia to claim referrals through fake clicks and take credit for sales that other publishers should have gotten the commission for.

The allegations against Phia come from investigations by researcher Ben Edelman, Bloomberg, and Capital One Shopping, which all reportedly found instances of the browser extension claiming referrals through fake clicks. According to Edelman’s research, Phia’s ‘affiliate link invisibly loaded into a second tab’ on iOS after visiting a merchant’s website, allowing it to claim credit for sales it didn’t actually drive.

Phia, which was co-founded by Phoebe Gates, Bill Gates’ daughter, and Sophia Kianni, has blamed the issues highlighted in the investigations on a bug. In a statement to Bloomberg, a spokesperson for the company said, ‘Within the last 24 hours, we were made aware that in a recent release our codebase was causing misattributions from a subset of users. As soon as we were notified, our team worked overnight to identify, mitigate, and has since resolved the issue.’

The feature that enabled all of this rolled out in December 2025, Edelman and Bloomberg both reported. This is not the first time that Phia has been accused of affiliate marketing abuse. In the past, the company has faced criticism for its aggressive affiliate marketing tactics, which some have described as ‘deceptive’ and ‘unfair’.

Cookie stuffing is a form of affiliate marketing abuse that involves attaching an affiliate code to a sale that the affiliate did not actually drive. This allows the affiliate to claim credit for the sale and earn a commission, even though they did not actually contribute to the sale. Cookie stuffing is a serious issue in the affiliate marketing industry, as it can lead to a loss of trust and revenue for publishers and merchants.

Phia’s use of cookie stuffing is a serious issue that raises questions about the company’s business practices and its commitment to transparency and fairness. The company’s response to the allegations, blaming a bug and claiming that it has since resolved the issue, may not be enough to restore trust in the company.

In light of these allegations, it is worth considering the potential consequences of Phia’s actions. If the company is found to have engaged in affiliate marketing abuse, it could face serious consequences, including fines, penalties, and damage to its reputation.

The Phia controversy highlights the need for greater transparency and accountability in the affiliate marketing industry. Publishers and merchants need to be aware of the potential risks of affiliate marketing abuse and take steps to protect themselves. This includes being cautious when working with affiliates, monitoring their activity closely, and taking action if they suspect that an affiliate is engaging in abusive practices.

Ultimately, the Phia controversy serves as a reminder of the importance of transparency and fairness in business. Companies need to prioritize these values in order to build trust with their customers and maintain a positive reputation.
