Phia

Phia is a personal shopping assistant that helps consumers build their closet and find the best prices instantly across the web. Co-founded by Phoebe Gates and Sophia Kianni, the product spans a mobile app and a browser extension that compares prices for a given item across new and resale marketplaces, tracking more than 700 fashion, beauty, and lifestyle brands. The public phia.com site is a consumer storefront (a brand directory plus editorial style edits) and exposes no developer API, documentation, or programmatic surface. This profile was surfaced as a portfolio company of GGV Capital and enriched from live probes of the public site.

Phia is profiled on the APIs.io network. Tagged areas include Company, Ecommerce, Shopping, Fashion, and Retail.
