Elliott Green

Elliott Green is the co-founder and CEO of Dandelion Health, a New York-based real-world data and clinical AI platform building multimodal, longitudinal datasets from a consortium of non-academic health systems. A former founding member of Oscar Health with a finance background, Green launched Dandelion in 2020 to give life science companies and AI developers unbiased, clinical-grade data - including the images, waveforms, and notes that make up most of medicine but are rarely used. The company closed a $14M Series A in 2026 and has launched a free AI validation service and a GLP-1 data library aimed at bringing precision medicine to cardiometabolic disease.
