Phoebe Yao is the founder and CEO of Pareto.AI, building human-in-the-loop systems that capture frontier human intelligence for partners like Anthropic and Character.ai. With nine years of experience and a Human-Centered Design & Engineering degree from Stanford (plus HCI study at Oxford), she blends research rigor with product-first startup execution. Her background includes research stints at Stanford and Microsoft and a Thiel Fellowship, signaling a track record of translating academic insight into commercial AI tooling. Phoebe focuses on keeping humans relevant in automated workflows, designing interfaces and data pipelines that surface high-value human judgments for model training. Based in Palo Alto, she combines founder-level strategy with hands-on experimentation in ML-human collaboration, often working at the intersection of design, ethics, and scalable data systems. An underappreciated strength is her ability to operationalize nuanced human expertise at scale—turning qualitative judgment into structured signals for cutting-edge AI.
