Phia

Phia is an AI-native shopping agent co-founded by Phoebe Gates and Sophia Kianni that sits in the browser, surfaces best prices in real time, and acts as an alignment layer between shoppers and 6,200+ brand partners. It is relevant to retail AI as a platform that demonstrably improves conversion rates and reduces returns, earning it a software valuation multiple. Phia operates on a revenue-sharing model with its brand partners rather than charging advertising fees, aligning its economics with actual transactions rather than impressions. Its co-founders' public profiles have accelerated brand partnership acquisition in a market crowded with browser extension competitors, while the returns-reduction metric gives it a concrete ROI argument that most shopping discovery tools cannot quantify.
