Analysis
Phia, the shopping-comparison startup co-founded by Phoebe Gates and Sophia Kianni, has raised more than $43 million and carries a valuation of roughly $185 million, according to a Fortune profile published July 11 in which Gates said she wants the company to succeed with "no ties to my privilege or my last name." The company's browser extension helps users compare prices across retailers and surface discount codes, positioned as a Google Flights-style tool for online shopping.
That framing collided directly with a separate Bloomberg investigation, reported by TechCrunch on July 10, which found Phia engaged in "cookie stuffing" -- a deceptive affiliate-marketing practice where, when a user shopped at an online retailer, even arriving independently or through a competing affiliate program like Wirecutter, Phia would silently open a background browser tab during checkout and override the existing referral code with its own, allowing it to claim commission credit on purchases it hadn't actually generated or influenced.
The practice triggered Phia's suspension from Impact.com, a leading affiliate and influencer marketing platform that many retailers and publishers rely on to track and pay legitimate referral commissions. A Phia spokesperson told Bloomberg that all necessary changes had been made to fix the issue, and Bloomberg's own follow-up verification found the behavior had since been resolved -- but the episode surfaced only after weeks of investigative reporting, not through Phia's own disclosure.
For founders building on affiliate-revenue models, the episode is a pointed reminder that growth metrics built partly on affiliate commission capture face real scrutiny once a company reaches enough scale and visibility to attract investigative journalism -- and that platform partners like Impact.com will act decisively once deceptive practices are documented. For investors, the timing is awkward: a glowing founder profile and a fraud investigation breaking within a day of each other is exactly the kind of juxtaposition that damages both the company's credibility and its next fundraising conversation.
The bear case: even with the specific cookie-stuffing behavior reportedly fixed, the episode raises broader questions about how much of Phia's historical revenue and growth metrics were inflated by commissions it didn't legitimately earn, a question early investors and any future round's diligence process will need to answer directly. What to watch next: whether Impact.com reinstates Phia's account, and whether other affiliate networks or retail partners conduct their own reviews of Phia's historical commission claims.
