Phia, the shopping startup co-founded by Phoebe Gates and Sophia Kianni, is facing scrutiny after a Bloomberg investigation alleged the company benefited from a digital marketing practice known as “cookie stuffing.” The report said the practice helped Phia receive commissions or sales credit for purchases it may not have directly generated.
Cookie stuffing generally refers to placing affiliate tracking cookies on a user’s device without a clear, qualifying referral action. In affiliate marketing, retailers often pay publishers, apps or influencers when they send a shopper to a store and that shopper completes a purchase. Tracking cookies are used to identify which partner deserves credit. When cookies are placed improperly, an affiliate can be credited for a sale even if the consumer arrived at the retailer through another path.
The allegations place Phia in a broader debate over how shopping tools, browser extensions and deal-finding services earn money online. Many such products operate on affiliate revenue, collecting a fee when users click through to merchants or complete purchases. That model is common, but it depends on accurate attribution and clear rules about when a commission is earned.
What the allegations mean
According to the Bloomberg report, Phia’s technology was able to secure affiliate credit in circumstances where the startup did not necessarily influence the shopper’s decision or route them to the retailer in a meaningful way. That distinction matters because affiliate programs are designed to reward partners that deliver traffic, customers or measurable value to merchants.
If affiliate credit is assigned incorrectly, other marketing partners may lose commissions, retailers may pay for sales they would have received anyway, and consumers may have little visibility into how their browsing activity is being tracked. The issue also raises questions about disclosure, consent and the technical design of shopping products that run in the background while users browse.
Phia has attracted attention in part because of its founders. Gates, the daughter of Microsoft co-founder Bill Gates, and Kianni, a climate activist and entrepreneur, launched the company with a focus on helping shoppers compare prices and make more informed purchasing decisions. The company’s profile has made the allegations more visible in the technology and retail sectors.
Affiliate marketing under pressure
The controversy comes as regulators, retailers and affiliate networks pay closer attention to online tracking practices. Companies that rely on cookies and browser-based tools have faced increasing pressure to explain how data is collected and how commissions are attributed. Retailers also have an incentive to police affiliate programs because inaccurate tracking can increase marketing costs without producing new customers.
The report does not mean Phia has been found liable for wrongdoing. Allegations involving cookie stuffing often turn on technical details, contract terms and the rules set by affiliate networks or merchants. Still, the scrutiny could create reputational and business challenges for the startup if retail partners or affiliate platforms review its practices.
For consumers, the case is a reminder that free shopping tools often generate revenue through referral payments. Those commissions can support useful services, but they also make transparency important. Users may want to review browser permissions, privacy settings and disclosures from apps that assist with online purchases.
