When Phoebe Gates and Sophia Kianni, co-founders of Phia, set out to build an AI startup, they focused on a domain they knew intimately: online shopping. Their shared experience as Stanford roommates navigating the complexities of e-commerce sparked the vision for a tool that could transform how consumers discover, compare, and purchase products. Phia’s founding principle was simple yet ambitious: to provide every shopper with a personal assistant in their pocket, helping them answer the pivotal question, “What should I buy?”
Emerging from a Stanford class project, Phia’s platform offers a browser extension and mobile app that enable users to compare prices across a vast inventory, including second-hand items. The integration with over 150 resale platforms allows access to an in-house database of more than 350 million products. Sophia Kianni highlights the environmental benefits of their approach: purchasing second-hand items reduces carbon footprints by approximately 80% compared to buying new, while also providing cost savings.
“There felt like there was this giant white space for, like, what should we actually buy, and why doesn’t everyone have a personal shopper in their pocket?” – Phoebe Gates, Co-Founder of Phia
Empowering Consumers with Value and Fit Intelligence
Phia’s AI advisor goes beyond price comparison by providing insights into the resale value of items. For example, it helps users understand the potential depreciation of products like fast fashion versus luxury handbags, enabling more informed purchasing decisions. Additionally, Phia is piloting a sizing feature that predicts fit based on users’ previous orders and returns, addressing a common pain point in online apparel shopping.
Building Audience Engagement Through Authenticity and Content
To grow its user base, Phia employs diverse tactics including an ambassador program, original content documenting product development, and a podcast. These efforts have driven hundreds of thousands of downloads at low acquisition costs. Phoebe Gates emphasizes the importance of transparency in connecting with users, noting that sharing the realities of startup life fosters genuine engagement.
“I think there was a bit of an ego death that we had to go through… to make content at the volume that we need to, you need to be able to just pull back the curtain.” – Phoebe Gates, Co-Founder of Phia
Founders’ Perspective and Unique Insight
While Gates acknowledges the privileges that come with her background, she emphasizes that Phia’s product is designed for everyday shoppers, not tech elites. This grounded perspective informs the startup’s user-centric approach.
