The Genetics Podcast

This week on The Genetics Podcast, Patrick is joined by Stevie Ringel, co-founder of Nome and founder of the Kizuna Foundation. They discuss Stevie's own ultra-rare disease diagnosis and shaped his path to founding Kizuna Foundation and Nome, how Nome's AI agents help scientists navigate the operational complexity of small-batch drug development, the technical and business model advantages underpinning Nome's accuracy, and what it will take to build a sustainable funding model for ultra-rare disease.
