Ellen Rudolph
Ellen Rudolph is the Co-Founder and CEO of WellTheory, a San Francisco-based digital health company on a mission to reverse the autoimmune epidemic. A Stanford-trained product design engineer and Functional Medicine Certified Health Coach, Ellen founded WellTheory in 2022 after her own years-long battle with debilitating autoimmune symptoms drove her to create the empathetic, evidence-based care she wished she'd had. WellTheory has since raised $33.4M in total funding—including a $14M Series A led by General Catalyst in October 2025—and achieved 10x year-over-year member growth and 5x revenue growth, serving 50 million Americans navigating autoimmune conditions.
